A Colt Visit

The city of Hartford in Connecticut is Mecca if you are a Colt fan (as in Colt firearms), and I sure am a Colt fan.   I grew up seeing Colt .45 sixguns in western movies when I was a kid and I got my first Colt (a .45 ACP 1911 Government Model) when I finished college (and I’ve never not owned at least one Colt since then).  I have no tattoos, but if I were going to get one it would be the Colt logo.

My Colt 1911 has been sending lead downrange for 50 years.

I made a friend in the Colt company when reviving the MacManus award.   I had to be in Hartford recently for a symposium and I told my Colt buddy I’d buy him a beer.  He suggested a tour of the Colt factory.  That was an opportunity I could not let pass.

The original Colt plant (the one built by Sam Colt) is a National Historic Site.  Time did not permit visiting it, but I could see the blue dome above the old plant from my hotel window.

The original Colt manufacturing facility on the banks of the Connecticut River. I didn’t get to it, but the next time I’m in Hartford I will.

The modern Colt factory is a few miles from downtown Hartford.  It’s what you see in the big photo up top, and it’s where I had the plant tour described in this blog.  The bad news is that photography is prohibited inside the plant (as a manufacturer of military rifles for the US and other countries, Colt can’t have photos of their production processes finding their way to the bad guys).  The good news is that I entered the inner sanctum.  I saw how the M4s, the M16s , the 1911s, the Single Action Armys, the Pythons, and all the other cool stuff are made.  As a manufacturing guy and gun guy with a defense industry background, it was one of the best days of my life.

More good news is that I could take pictures inside the famed Colt Custom Shop.  The Custom Shop is a small group of world class artists who assemble what are arguably the most desirable guns in the world.  Think engraved, gold inlaid, extremely expensive works of the gunmaker’s art.   Guns that are delivered to US presidents, wealthy collectors, and…well, you get the idea.  There’s a two-year waiting list for a Custom Shop Colt firearm, and when delivered, the ticket can exceed the cost of a new car.  On the secondary market, some have been known to exceed the cost of a new home.

Colt Custom Shop handguns, the stuff of dreams.
You can still purchase a brand new Colt 1903 through the Custom Shop. This one is exquisite. I owned one in the 1970s I bought it for $75 and sold for $200 a few months later, thinking I had done well.  Ah, the mistakes we make.

Colt’s Custom Shop is producing a series of Single Action Army revolvers for the legendary Texas Rangers.  The Texas Rangers are the oldest law enforcement organization in America.
Colt has a process for making a new gun look aged.  It’s been applied to this Custom Shop Single Action Army.

This was my second visit to Hartford.  When I wrote The Gatling Gun nearly 30 years ago, I contacted Colt to ask if I could visit their archives (the original Gatling guns were built by Colt).   Colt referred me to the Connecticut State Library and Museum.  I went there and I was met by a Connecticut State Trooper who asked me a few questions, took my fingerprints, and ran a background check.   Satisfied I wasn’t a terrorist or a  KGB agent, he issued a laminated permit designating me an official Connecticut state historian.  That gave me access to the archives in a secure area of the Museum.  Poking around in there made for a fun day, and I used materials from those archives when I wrote The Gatling Gun.

My visit to the Colt archives three decades ago was impressive.  I handled hand-written documents signed by Dr. Gatling and Samuel Colt.  It was a great day and a lifelong memory.   My recent visit to Colt factory and the Custom Shop (as described in this blog) made for an even better day.   A Colt tattoo….maybe that’s not a bad idea.

1903 Springfield Cast and Jacketed Loads

This is an update on my latest 1903 Springfield load development work.

I purchased this rifle about three years ago assuming the headspace was correct, but it wasn’t.  That’s a risk associated with old military rifles.  Rifle parts are often mixed through the years, and when doing so with the bolt and the barreled action, it’s easy to induce an excess headspace condition.  That’s what I encountered on my rifle, so I had the Civilian Marksmanship Program (CMP) in Anniston, Alabama install a new 1903 barrel and rechamber the rifle.  Live and learn, I guess.  Always check the headspace when purchasing a milsurp rifle.

As it was returned to me from the CMP the rifle shot to the right and jacketed bullets shot way too high (at least I thought it shot way too high, but I was wrong…more on that in a bit).  I  noticed that the front sight was biased to the left (which made the rifle shoot to the right).  I drifted the front sight in its base (it’s a dovetail fitting).  The front sight takes a retaining screw that secures it to the barrel mount, and on my rifle that screw was missing.  It might have shipped that way from the CMP or it might have fallen out.

When the Springfield was returned to me from the CMP, the front sight was biased to the left, as you see here.  I didn’t notice it at first.
A replacement front sight screw.

I wrote to the CMP regarding the missing front sight screw, but I haven’t heard from them and I found a replacement front sight screw on the Sarco website.  I haven’t installed it yet (that will come later).  I drifted the front sight in its dovetail to the right, and that brought the point of impact closer to the point of aim.

Before I get into the reloading specifics, I should explain a bit about the rear sight.  The rear sight on the 1903 Springfield rifle is a complicated device.  It’s called the M1905 rear sight, and it is designed and calibrated for standard military ball ammo (back in the day when the Army used .30 06 ball ammo).   The sight is a ladder type rear sight and it has four aiming methods.  One is the battlesight zero (it’s with the ladder down); the other three are with the ladder up which allows adjusting for various distances.  In the big photo at the top of this blog, you see the rear sight with the ladder up.  In the photo below, you see the rear sight with the ladder down.

The M1905 rear sight assembly on the 1903 Springfield rifle. The sight ladder is in the down, or battlesight zero position. Wow, there’s a lot going on there.

This first aiming method is through the battlesight zero notch with the ladder down. Battlesight zero means the bullet will coincide with the point of aim at 547 yards.  The thought is that if you hold center of mass on a man-sized target at any distance up to 547 yards, you’ll hit the target.  At 100 yards the rifle will shoot way high with the ladder down using the battlesight zero, which is what I experienced.  I did not understand this was a normal occurrence when using the battlesight zero rear sight notch.

The 1903 Springfield’s rear sight in the raised position.  Note that the sides of the rear sight force the crossbar to the left as distance to the target increases.  That’s a built-in feature to compensate for bullet drift to the right at longer distances.  Clever people, those Army engineers were.  This rifle is over 100 years old.

The other three aiming methods all involve shooting with the ladder up (as you see in the above photo).   You can adjust for various ranges from 100 yards out to 2800 yards (which is roughly a mile and a half) by loosening the crossbar lock screw and sliding the crossbar up or down to various indicated ranges on the ladder.  One sighing method uses the crossbar upper notch.  You simply slide the crossbar up or down so that the top of the notch aligns with the estimated distance to the target (in yards) on the ladder’s distance graduations.  Another sighting method uses the crossbar lower notch.  In this case, you slide the crossbar up or down so that the top of this lower notch aligns with the estimated distance to the target.  The last sighting method involves using the crossbar aperture. There’s a horizonal scribe line across the plate containing this aperture, and when using the aperture, you align that scribe line with the estimated distance to the target.  The aperture allows zeroing the rifle for ranges as close at 100 yards, which is where I do most of my shooting.

All the above is calibrated for standard military .30 06 ball ammo.  If you’re shooting cast bullet ammo, or jacketed ammo with bullet weights or velocities other than standard ball ammo, you have to zero your rifle for your specific load.

There’s one other bit of coolness incorporated into the design of this rear sight.  The sight ladder is designed so that as you raise the crossbar, the sighting notches and aperture move to the left.  That’s to compensate for the bullet’s natural drift to the right as distances increase.

It’s all very clever, but in my opinion the Army made it too complicated. The rear sight was probably designed by an engineer who never had to carry or use a rifle in the field or train recruits to do so.  I think most of the guys I served with in the Army would have a hard time remembering all this (I’m an engineer and I struggled to understand it).  Apparently the Army agreed:  They simplified the rear sight on the later 1903A3 rifle.  The 1903A3 rear sight is much better for an infantry rifle.

That’s enough background on the 1903 Springfield sights.  Let’s get to the reloading variables and which loads the Springfield likes.  I prepped several, and I also grabbed some of the ammo I had previously loaded for the M1 Garand.

Four bullets used in this testing. From left to right: The Hursman 173-grain cast bullet, the Montana 210-grain cast bullet, the Winchester 150 grain jacketed soft point bullet, and the jacketed Speer 168-grain Match bullet.
The Hursman cast bullet loaded in a .30 06 cartridge.

I first fired at a 5o-yard silhouette target to see where the bullets were hitting (there’s lots of real estate on that target).  With the ladder down, the point of impact was to the right and low using the 17.0-grain Trail Boss and 173-grain Hursman bullet load.  With the ladder up, it moved left a little and printed higher using the higher rear sight notch.  For that 0.793 group up top, I used the bottom edge of the upper left box as the aimpoint.  For the other two groups, it was the bottom of the orange bullseye.

An initial target shot with cast bullets and Trail Boss powder. There’s a lot of real estate on this target, so I could see where the rifle was shooting.

I shot groups at 50 yards with several different loads using combinations of the bullets shown above and SR 4759, Trail Boss, 5744, and IMR 4064 propellants, all at 50 yards, and all with neck-sized-only .30 06 brass.  Then I returned a week later and fired groups with the 150-grain jacketed Winchester bullets (again at 50 yards).

After shooting the above groups, I had 20 rounds left with the Trail Boss,  Hursman bullet, and SR 4759 load.  I shot two of them at a clump of dirt at about 80 yards and hit it (I think) both times.   Then I put a 100-yard small bore rifle target up at 100 yards and shot at it with the 173-grain cast bullet SR 4759 load (8 rounds were crimped, and 10 rounds were not).  To my surprise, all 18 rounds were on the paper and 14 of the 18 were in the black.  It’s not that great a 100-yard group, but it shows potential.  All this was with the ladder down using  the battlesight zero sighting approach, so with cast bullets this rifle (at least with the SR 4759 load) is pretty much in the ballpark.

Cast bullets at 100 yards using the battlesight zero rear sight.

For the jacketed loads, I used the 150-grain Winchester jacketed soft point bullet (I bought a bunch of these a few years ago when somebody had them on sale) and 48.0 grains of IMR 4064.  This is the accuracy load in the Lyman reloading manual with a 150-grain jacketed bullet, and I know from prior development work it is superbly accurate in my Model 70.  It is also a minimum load, which is nice given the 1903’s steel buttplate.  The 1903 did well at 50 yards with the Winchester bullets, so I posted another silhouette target at 100 yards.  I fired three rounds and it was rough shooting at that target.  Using the aperture, I literally could not see the orange bullseye at 100 yards when I focused on the front sight.  The orange bullseye disappeared until I shifted my focus to the target.  I’d acquire the bullseye, then rapidly shift my focus to the front sight and squeeze the trigger.  I did that three times, literally firing blind, and managed to get a 3.050-inch 3-shot group.

The 150-grain jacketed Winchester bullet load at 100 yards. I couldn’t keep the orange bullseye visible using the aperture at 100 yards.

I figured it was time to quit while I was ahead.  I didn’t have any more black bullseye targets with me.  I knew I would be able to see those focusing on the 1903’s front post while sighting with the aperture.  But with the orange bullseyes (like you see in the target above), I might as well have been shooting at night.  I returned to the range a few days later and shot at 100 yards with the jacketed 150-grain Winchester bullets (with the 48.0-grain IMR 4064 load), the 210-grain cast Montana bullets (with the 17.0-grain Trail Boss load), and the 168-grain Speer match bullets (with a 48.0 grain IMR 4064 load).

Using the rear sight aperture, I shot the target below at 100 yards with the 150-grain Winchester jacketed bullet and 48.0 grains of IMR 4064.  I was pleased with the results and I quit after 3 shots (I didn’t want to screw up the group).

Three shots into an inch and three quarters at 100 yards. The load was 48.0 grains of IMR 4064 and the Winchester 150-grain jacketed soft point bullet.  Old eyes and an even older rifle sometimes do great things.  My rifle was manufactured in 1918; I was born in 1951.

I then shot at another 100-yard target with the 210-grain Montana cast bullet (these were loaded with 17.0 grains of Trail Boss).  I used the rear sight’s lower notch for this target.  Hmm, what do you know…the elevation was about perfect without moving anything on the rear sight.

Another 100 yard target, this time with the Montana 210-grain cast bullet and 17.0 grains of Trail Boss. I used the rear sight notch immediately above the aperture without making any adjustments. This is a real sweetheart load with minimal muzzle blast, almost no recoil, and no leading. The cast bullets are not as accurate at 100 yards as are the jacketed bullets, but they are still pretty good.

Finally, I fired eight rounds originally loaded for the Garand (I reload for the Garand in multiples of eight, as that’s what a clip holds), returning again to the rear sight aperture. This load used the 168-grain Speer jacketed boattail hollowpoint bullet and 48.0 grains of IMR 4064 propellant.  The Speer bullets are almost identical to the Sierra match bullet, but the Speer’s ogive is slighly different and it has less bearing area in the barrel.  I called the wizards at Speer about that and they recommended going to a heavier charge than would be used with the comparable Sierra bullet (they specifically recommended 48.0 grains of IMR 4064 for the Garand).  That load was a little warm in the 1903 (the recoil was significantly more than the 150-grain Winchester bullet and the primers had slight flattening).  But it was reasonably accurate.

Eight rounds of .30 06 ammo loaded for the Garand, using the 1903 rear sight aperture, at 100 yards. The astute blogophile will note there appears to be only seven holes; the hole just outside the 10-ring had two bullets pass through it.

My observations and conclusions from the above are:

    • The 1903 Springfield rear sight is needlessly complex for an infantry rifle.  You may feel differently.  Hey, go start your own blog.
    • With my cast bullet loads, there was no leading.   My cast bullets had gas checks (the little copper cup on the bullet base), which helps to prevent leading.
    • The Lyman cast bullet book showed a minimal 5744 load to be the accuracy load for the 210-grain Montana cast bullet.  I did not find that to be the case.
    • Both the Hursman 173-grain and the Montana 210-grain cast bullets were extremely accurate with 17.0 grains of Trail Boss, at least at 50 yards.
    • The Winchester 150-grain jacketed bullet accuracy load, per the Lyman manual, was with 48.0 grains of IMR 4064.  I found this to be a very accurate load.  I didn’t do a lot of work developing a jacketed bullet load.  I’m going to stick with this one for this rifle.
    • Orange bullseyes and aperture rear sights don’t work with my old eyes at 100 yards.  They are okay at 50 yards, but not 100 yards.
    • Both of the jacketed bullet loads I tried (the Speer Garand load and the Lyman 150-grain accuracy load) are accurate.  Without adjusting the rear sight from the 150-grain jacketed bullet setting, the Garand load shoots a little high and to the right, but the group size would fit into the bullseye if the sights were adjusted.
    • The cast bullets are not as accurate as the jacketed bullets at 100 yards.  The cast bullets are comparabily accurate to jacketed bullets at 50 yards, but not at 100.

With regard to shooting both cast and jacketed bullets in the same rifle, I got lucky:  As complicated as that 1903 Springfield rear sight is, I found that one rear sight position shoots to the same point of impact at 100 yards for both my cast bullet accuracy load and my jacketed bullet accuracy load.  Yep, you read that right.  With the rear sight crossbar secured as you see in the photo below, I can use the aperture (denoted by the right arrow) with the 150-grain jacketed bullet load.  Or, I can use the lower crossbar notch (denoted by the left arrow) with the 210-grain cast bullet, 17.0 grains of Trail Boss load.  Both will shoot to the same point of impact at 100 yards.  A friend asked if I tuned the loads to do this.  I wish I could say I had that kind of load development expertise.  Nope, I just got lucky.

One size fits all (sort of). With the 1903’s rear sight in the raised position, I use the notch denoted by the arrow on the left for my cast bullet accuracy load at 100 yards. I use the aperature denoted by the arrow on the right for the 150-grain jacketed bullet load at 100 yards. I don’t need to move the rear sight cross bar up or down.  Sometimes you just get lucky.

One final note that’s sure to set the Internet on fire:  I know this is heresy.  As much as I like my 1903, I think the 91/30 Mosin Nagant is a better rifle. My Mosin groups better at 1oo yards.  But that’s a story for another blog.

The CMP Custom Gunshop, a 1903 Springfield, and Cast Bullets

This is an interesting story and it’s one of the very few times in my life I was hosed on a firearm purchase.  The rifle is a 1903 Springfield I bought a few years ago and didn’t shoot much.  The times I shot it previously I had experimented with cast bullets and it shot okay, but not great.  Then I tried it with jacketed bullets (loads at much higher pressures), and what do you know, I had a headspace issue.  I could see it in the primers that had partially backed out of the brass after firing, and on one round, I split a case circumferentially just ahead of the base (indicating with near certainty an excess head space issue).  I borrowed good buddy Greg’s 30 06 head space gages, and the bolt closed on both the no go and the field service gages.  That’s a no no.

The 1903 Springfield rear sight. The 1903A3 went to a much less expensive stamped steel rear aperture sight.

My first thought was to have the existing barrel set back and rechambered, but that didn’t work.  The 1903 Springfield has a barrel collar that holds a very sophisticated rear sight and positions the upper handguard.  When we set the barrel back, the rear sight integrity was greatly weakened and the front handguard had excess play.  Nope, I needed a new barrel.

I checked around and came to the conclusion that the best place to get this kind of work done is the Civilian Marksmanship Program (CMP) Custom Gunshop.  This is a quasi-government arsenal and these folks are the experts.   I priced having a new barrel and rear sight collar installed on my 1903, cutting a new 30 06 chamber with the correct headspace, and having the entire gun re-Parkerized.  The work was surprisingly reasonable.  I had to wait my turn in line, but that’s okay.  I had other guns I could shoot.

With a re-Parkerized finish and a new barrel, my 1903 looks great.
Very cool. The 1903 “scant” stock, complete with cartouche.

When the rifle was returned to me, it was stunning.  It literally looked like a brand new 1903.  A quick trip to the range followed, and I tried some jacketed bullet factory level reloads.  I loaded and fed from the magazine, as the 1903 is a controlled round feed and it’s best in these guns to let the cartridge rim ride up and find its position behind the extractor.

A 30 06 cartridge in the 1903’s magazine.

I shot a few targets with copper jacketed bullets and found that the rifle shot about a 8 inches high and slightly to the right.  The rear sight would take care of the right bias, and I figured the high impacts were okay.  Some military rifles of this era are designed with a 300-yard battlesight zero, which means they shoot to point of aim at 300 yards at the lowest sight setting (everything in between is high, with the idea being that if you hold center-of-mass on a human size target, you’ll have a hit out to 400 or 500 yards).

High and slightly to the right with factory-level reloads. My point of aim was 6:00 on the orange bullseye.

I could buy a taller front sight blade to lower the point of impact, but that wasn’t the way I wanted to go.  Nope, my plan was to shoot cast bullets in this rifle.  My guess was that if the rifle shot 8 inches high at 50 yards with jacketed bullets, cast bullets would be right where I wanted them to be.

Loading my first batch of 1903 cast bullet test ammo was easy.  Years ago I was on a reloading tear, and I had loaded a bunch of plated 110-grain round nose bullets with 14.0 grains of Unique.  I knew those loads were terrible in other 30 06 rifles (the lead under the copper plating is dead soft and it tears off, resulting in terrible accuracy).  Hey, no problem.  I pulled the plated bullets, left the 14.0 grains of Unique in the cartridges, flared the case mouths, and seated different cast bullets.  One was the 180-grain cast Hursman bullets with gas checks (these worked well in the .300 Weatherby), the other was the 210-grain Montana bullets I picked up from good buddy Paul (these are also gas checked bullets).  After seating the cast bullets, I crimped the brass with my Lee factory crimp die.

30 06 reloads with cast bullets. That’s the Montana bullet on the upper cartridge, and the Hursman bullet in the lower cartridge.  If you look closely, you can see that the case mouth has been crimped by the Lee factory crimp die.

A similar photo of the Montana bullet. It’s cast with a Lyman mold. The Montana bullet’s rounded nose fed better from the 1903 magazine.

I only loaded 20 rounds (10 each with the two different cast bullets), as this was to be a “quick look” evaluation.

A morning at the range on an overcast day, a beautiful 1903 Springfield rifle, and .30 06 ammo loaded with cast bullets. Life doesn’t get much better.

Both loads shot reasonably well.   I’m not going into the upholstery business with either of these loads (they are not tack drivers), but they are good enough.  I was particularly pleased with the 210-grain Montana bullets.  The Hursman bullets had proved to be the preferred load in the .300 Weatherby; the Springfield showed a decided preference for the Montana bullets.

I shot at 50 yards with both loads; future testing will be with the Montana bullet at 100 yards.

The Hursman bullet load at 50 yards. The load was 14.0 grains of Unique; it may be that the Hursman bullets will group better with other propellants.
The Montana bullet at 50 yards on the left-most bullseye (the other bullseyes were shot with a Mosin-Nagnt rifle, covered in another blog). I found a sweet spot with that 14.0-grain Unique load and the Montana bullet.

Unique is not the best powder out there for loading cast bullets in rifle cartridges.  In the past, I’ve shot much better groups in other rifles with IMR 4227, 5744, SR 4759, and Trail Boss.  Those evaluations in the 1903 are coming up.  For now, I know I’ve got a good load with Unique and the Montana bullets.

One of the big takeaways for me in this adventure is that when you buy a milsurp rifle, always check the headspace to make sure that it is within specification.   It’s pretty common for these rifles to have gone through arsenal rebuilds and to have been cobbled together from parts bins, and when that occurs, if the chamber isn’t matched to the bolt you can have an excess headspace problem.   That’s a bad situation, as it can be dangerous to the shooter and anyone nearby.

You can find headspace gages on Amazon and elsewhere.  If you’re going to buy a military surplus rifle, checking the headspace should be part of the drill.
