When I first saw Mosin-Nagant military surplus rifles for sale in a Big 5 sporting goods store years ago, I dismissed them as junk. Wow, was that ever a mistake. I’ve previously written about being smitten with these Russian rifles, and my appreciation for them continues unabated. Back in the day, you could pick them up for $79. That was after the Soviet Union collapsed and the Russians were sending Mosins over here by the boatload to raise cash. Then, during the Obama administration, the flow of these rifles to the US stopped. Today, a Mosin will set you back $300 or more (and it’s mostly more). I recognized the inherent quality and probable appreciation after shooting the first one I bought. I knew Mosin prices would climb and I picked up several. My two favorites are the ones you see in the photo above.
I use the first Mosin I ever bought (the one on top in the above photo) for shooting jacketed bullets. It has a bore that looks like a sewer pipe, but it is accurate. Here’s a recent 100-yard target.
There are 20 shots on this 100-yard target. The two that went low? Chalk it up to operator error.
I don’t use surplus 7.62x54R ammo in my Mosin-Nagant rifles. Surplus ammo used to be cheap and readily available, but not anymore. Even when surplus ammo was around, I didn’t use it because the primers were corrosive. I shoot only my reloads in the Mosins. Just about any 150-grain, .312 diameter jacketed bullet works well with 43.7 grains of IMR 4320 propellant. That powder is no longer available, but I have a stash. When I use it up, I’ll probably switch to Varget or IMR 4064 (both powders are said to work well in the 7.62x54R cartridge).
My Mosin-Nagant jacketed bullet load. It’s very accurate.
The other rifle Mosin you see above (the one on the bottom) is a beautiful hex receiver with a bore that appears to be brand new. When I fired it with jacketed bullets, it grouped very well, but it also shot very high with the rear sight in its lowest setting. I thought I would have to find a taller front sight, but I tried a few cast bullets and to my surprise, the rifle shot to point of aim at 50 yards. When I tried my cast bullet load at 100 yards, it was a scosh low. I went up one click on the rear sight and it was perfect.
My first 5 shots at 100 yards went low, wo I went up one click and put nearly all the rest in the 10-ring. Cast bullets can be very accurate.
My cast load for the Mosin is a 200-grain bullet sized to 0.313 inches over 18.0 grains of SR 4759. Like the IMR 4320 propellant mentioned above, SR 4759 is a discontinued powder, and like my situation with IMR 4320, I also have a stash of SR 4759. When I run out of it, there are other powders that work well with cast bullets. I’m looking forward to developing a new load with them. The load you see here sets a high bar, but I’m sure I can find a load that will match it.
I hadn’t shot cast bullets in my Mosin in a while. It didn’t matter; the rifle still shoots this load superbly well.
With both the Mosin-Nagant rifles you see above, I’ve refinished the stocks with several coats of TruOil (I sanded the stocks as little as possible to preserve the original cartouches). I’ve also glass bedded the actions and cleaned up the triggers. Both rifles are fun to shoot and both are superbly accurate.

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.

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.

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 macro shot of the Hursman 180 grain bullet. The case was crimped with a 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.
