I had my .30 06 Weatherby out last weekend. It was the first time I fired this rifle in maybe 35 years. I bought it at the Weatherby plant in South Gate, California, back when they used to let you in the warehouse to select the wood you wanted.
Fancy walnut and deep, deep bluing. I think I paid something around $300 for this rifle, new, in the 1980s. I’ll never sell it.
When I first shot this rifle in the mid-1980s, it didn’t group very well with my favorite .30 06 load (a 130-grain Hornady jacketed softpoint bullet and a max load of IMR 4320). That was the load I used in my Ruger No. 1 chasing jackrabbits in west Texas. Other things intervened to capture my attention, and I never got around to finding a load for this rifle.
Fast forward several decades, and for this outing I grabbed what was available in the ammo locker: A box of 168-grain Speer jacketed hollow point boat tail bullets (my Garand load), another box with Remington 180-grain jacketed soft point bullets (which are unfortunately no longer available), and a third box with 150-grain Hornady jacketed soft point bullets and 48.0 grains of IMR 4320 (which is also no longer available). What I learned on this most recent outing is that my Weatherby really likes the 180-grain Remington bullets and 48.0 grains of IMR 4064. It did acceptably well (for hunting purposes) with the other two loads, but that 180-grain Remington bullet and IMR 4064 is what answers the mail for me. It’s one of the places where accuracy lives in this rifle.
Before I left the house, I ran an oiled patch down the bore because as I said above the rifle hadn’t been shot in literally decades. When I first set up on the range, the rifle was throwing shots all over the place for the first few rounds. Then, either I or the rifle (or both of us) settled down and the Weatherby started grouping. Most of the other groups were in the 1.2-inch to 2.1-inch range (which is good enough for hunting deer and pigs), but the rifle really liked that 180-grain load. I’m talking sub-minute-of-angle. I couldn’t do this with every group, but it tells me the rifle will do its job (if I do mine).
When assessing a hunting rifle’s accuracy, I typically shoot 3-shot groups at 100 yards off the bench. Some folks like to shoot 5-shot groups, but it’s pretty hard to get the animals to sit still for 5 shots.Two shots through the same hole, and one a half inch away. I wish I could do this every time. The rifle is way more accurate than I am.
I was pleased with how the rifle performed, and I’ll probably start bringing it to the range more often.
A 12X, fixed-power Leupold scope with target knob adjustments and a sunshade. This is a nice setup.
I originally set up the 12X Leupold scope and this rifle for shooting in the standing position, so the scope sits high on the rifle. When I bought the rifle, I thought I would shoot metallic silhouette with it, but I never did. With the scope as high as it is, it was awkward shooting from the bench. That probably had something to do with the other groups opening up a bit, but I’m not complaining.
I wish Remington still sold bullets separately, but hey, life goes on. I have two boxes of the Remington bullets left, and when they’re gone, they’re gone. I also have a couple of boxes of Speer 180-grain jacketed bullets, and when I’ve run through my stash of Remington 180 bullets, I’ll try the Speers next. Speer still makes those. There are a few other loads I’m going to try, too. I’ll keep you posted.
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 M1 Garand on the bench at the West End Gun Club.
A couple of weeks ago I wrote about new bullets I had purchased for the Garand. They are Speer 168-grain Target Match bullets, and they’re designed to go head-to-head with the benchmark bullet in this arena, the Sierra 168-grain jacketed boat tail hollow point bullet. As you will recall, I talked to the Speer engineer and he recommended bumping the IMR 4064 propellant charge up from what I had tried previously and seating the bullets out a little further.
Speer 168-grain jacketed hollow point boat tail bullets.
I only had 20 Speer bullets left from the box of 100 I initially purchased and Phillips, my local dealer, didn’t have any more. I also had a couple of boxes of 178-grain Hornady AMAX bullets in my stash and my Hornady reloading manual had a Garand-specific load for these, so I loaded some of them for testing in the Garand as well. You can’t just use any .30 06 load for the Garand; the loads have to be specific for the Garand. If you go outside of what’s recommended for these rifles, you can damage the rifle.
Reloaded .30 06 ammunition with Hornady’s 178 grain AMAX bullets. I was concerned about the plastic tips hitting the feed ramp, but I need not have been. These bullets performed well.
It was windy out at the West End Gun Club this past weekend, so I don’t know if my results were the result of the load, or the wind, my shooting abilities, or all of the above. Take my results as an indication of what might work, not the ultimate authoritative conclusion on either bullet’s inherent accuracy. And as regards my propellant charges, work from your own manual. You will want to develop your own loads, starting at the bottom of the range and working up.
My testing for this session was limited. I had two loads for each bullet (both the Hornady and the Speer bullets), and all were with IMR 4064 propellant. I did all of my testing from the bench at 100 yards.
For the 178-grain Hornady AMAX bullets, I used 45.0 and 46.4 grains of IMR 4064, and a cartridge overall length of 3.240 inches. This load came right out of the Hornady reloading manual. For the 168-grain Speer bullets bullets, I used 47.0 and 48.0 grains of IMR 4064, and a cartridge overall length of 3.295 inches (as recommended by Speer). All loads were with Remington brass and CCI 200 primers. I trimmed the brass to 2.500 inches. This was the 6th firing of these cases in the Garand with these cases.
I reloaded and fired a total of 40 rounds for this test. I reload for the Garand in multiples of eight cartridges (because that’s what the en bloc clip holds), and like I said above, I only had 20 of the Speer bullets left. So bear with me (this is going to get a little complicated). I had one clip of eight rounds with the 168-grain Speers at 47.0 grains of IMR 4064, and one clip of eight rounds with the 168-grain Speers at 48.0 grains of IMR 4064. Then I did another clip of eight with the 178-grain Hornady bullets at 45.0 grains of IMR 4064, and a fourth clip of eight with the 178-grain Hornady bullets at 46.4 grains of IMR 4064. That left four of the Speer 168-grain bullets, so I loaded those four with 47.0 grains of IMR 4064, and then I loaded another four rounds with the Hornady 178-grain bullets and 45.0 grains of IMR 4064. Yep, you read that right. That en bloc clip had two different loads in it.
I had a concern that the plastic tips on the Hornady 178-grain AMAX bullets might be damaged sliding up the Garand’s feed ramp, but that didn’t occur. At the seating depth Hornady recommended, the bullets are pointed into the chamber and the tips never touched the feed ramp.
None of the 40 cartridges exhibited any pressure signs. There were no flattened primers, no excessive muzzle blast, no case ruptures, no extraction issues, or anything of that nature. Everything fed and ejected normally.
I fired the mixed clip of Hornady and Speer bullets first, and surprisingly, it was my best group of the day (it was also the only group I fired where there was a lull in the wind that morning). The first four shots were with the Hornady bullets, and of these, only one was just outside the bullseye (it might have been the first round fired from the cold, oiled barrel). All the remaining seven rounds shot into a pretty tight group, with six of the seven in the 10 ring. The bottom line based on this one group to me was that either load (the 178-grain Hornady load at 45.0 grains of 4064, and the 168-grain Speer load at 47.0 grains of 4064) were awesome, and both shot to the same point of impact.
The next group up was the 168-grain Speers with 47.0 grains of IMR 4064. I couldn’t duplicate my prior results as shown in the above photo. Six shots were in the black, two were out, and of these two, one was down in the 6 ring. It could have been the wind, or it could have been me. Most likely it was me (the wind wasn’t blowing down).
Then I fired the clip of eight with the Speer 168-grain bullets and 48.0 grains of IMR 4064. Five shots were in the black and three were outside, with one low at 7:00 in the 6 ring again.
It was on to the Hornady 178-grain bullets, first at 45.0 grains of IMR 4064. Five shots were in the black, one was in the 8 ring at 9:00, one was in the 7 ring at 10:00, and again, I had one shot go low in the 6 ring at 7:00. The group was biased to the left. That was probably the wind.
And finally, I shot the Hornady 178-grain bullets at 46.4 grains of IMR 4064. 6 were in the black, 1 was in the 8 ring at 9:00, and yet again, 1 was in the 6 ring at 7:00. These were a little more tightly clustered favoring the left side of the bullseye, consistent with the wind pushing the shots to one side (the wind at the West End Gun Club always blows northeast to southwest, pushing the shots to the left).
The bottom line is that any of loads could be good, but that first clip of mixed bullets was (for a guy at my low talent level) phenomenal. The wind no doubt distorted my results (along with my lack of consistency shooting the Garand). I have 180 of the Hornady bullets left, and I’m going to load them at 45.0 grains of IMR 4064. I’ll buy more of the 168 gr Speer bullets because they did well, too, and I’ll load them at 47.0 grains. I’m just not that good to say with certainty which load is best; the variability in group size you see here is probably more me than anything else.
The Speer bullets are the least expensive of the three brands I’ve tried in the Garand at $25/100. Next up are the Hornady AMAX bullets at $32/100. The Sierra 168-grain MatchKing bullets (not tested yesterday, as I had used all of them previously) are the most expensive at $37/100. If there’s a difference in performance between the bullets, I’m not good enough to see it. I have 180 of the Hornady bullets left, and I’m going to load them at 45.0 grains of IMR 4064 later today. I’ll buy more of the 168-grain Speer bullets because they did well, too, and I’ll load them with 47.0 grains of IMR 4064.
So which bullet works best in the Garand? Any of these are better than I am, and for a guy like me, evaluating accuracy at 100 yards with iron sights is subjective at best (my old eyes ain’t what they used to be). But I’m having fun, and I love shooting my Garand.
