By Joe Berk<\/h6>\n

Here’s a quick look at what I’ve found to be three Mosin-Nagant accuracy loads shot off the bench at 100 yards using the rifles’ standard open sights.\u00a0 I didn’t try to get too sophisticated for this quick comparison; I simply shot a 10-shot group with each load.\u00a0 All were at 100 yards.\u00a0 I used the NRA 25-yard handgun target because it’s what I had on hand (the bullseye on that target is slightly smaller than the 100-yard NRA rifle bullseye target, and it gave a decent aiming point).\u00a0 You’ll see the targets below.<\/p>\n

\"\"
My jacketed bullet Mosin. It’s one of my favorite rifles.<\/figcaption><\/figure>\n

My first two loads were with a rifle I use strictly for jacketed bullets.\u00a0 It’s my Tula 1940 round-top receiver.\u00a0 All you purists and keyboard commandos look away; this rifle is not for you.\u00a0 I refinished the stock with TruOil, I glass-bedded the action, and I reworked the trigger.\u00a0 As I’ve explained in earlier blogs, this rifle has a very rough bore, but the rifle remains blissfully ignorant of that fact and it shoots well.<\/p>\n

\"\"
My Mosin reserved exclusively for cast bullets. It’s another favorite.<\/figcaption><\/figure>\n

I shot the cast bullet load in a Mosin-Nagant rifle I use for cast bullets.\u00a0 It’s a 1928 Ivshevsk hex receiver with a relatively clean (i.e., unpitted) bore.\u00a0 When I first shot this rifle with jacketed bullets, I found that it shot a foot or more above the point of aim at 100 yards with the rear sight in its lowest setting.\u00a0 I could have compensated for that by finding a taller front sight, but I decided instead to use the rifle with cast bullets.\u00a0 It shoots cast bullets within the rear sight’s adjustment range.<\/p>\n

The Ammo<\/strong><\/p>\n

I shot 7.62x54R Russian reloaded ammo for this article.\u00a0 \u00a0Two of the loads used jacketed bullets; the third used cast bullets.<\/p>\n

\"\"
Three Mosin loads. From left to right, it’s the Hornady 150-grain polymer tipped bullet, the PPU 150-grain jacketed softpoint boat tail bullet, and the 200-grain cast bullet. The cast bullet is Lyman’s 314299 bullet sized to .313.<\/figcaption><\/figure>\n

The jacketed loads were identical other than the bullet and cartridge length:\u00a0 For one load, I used Hornady’s 150-grain polymer-tipped jacketed bullet; in the other, I used Privi Partizan’s 150-grain jacketed softpoint boattail bullet.\u00a0 I didn’t crimp either load, and I didn’t attempt to find the best seating depth.\u00a0 \u00a0The seating depths I used, though, worked well.\u00a0 Both loads used a charge of 43.7 grains of IMR 4320 propellant.<\/p>\n

\"\"
A bag of PPU 150-grain bullets. When these go on sale, I tend to stock up.<\/figcaption><\/figure>\n

The cast load used a 200-grain cast lead bullet with a gas check.\u00a0 I didn’t crimp the cast bullets, either, although I did use the Lee factory crimp die to remove the case mouth flare that prevented bullet shaving when the bullet was seated.\u00a0 This load used 18.0 grains of SR 4759 propellant.<\/p>\n

The astute reader and reloader will notice that several of the components I used for these loads are no longer available.\u00a0 The Hornady polymer-tipped 150-grain .312 bullets went out of production some time ago, as did the IMR 4320 and SR 4859 powders.\u00a0 It’s annoying, because when I get a load that works, I’d like to be able to load it again.\u00a0 I’ve got a good stash of IMR 4320 and that will probably last me the rest of my life (it’s a powder that works well for .30 06 and several other cartridges).\u00a0 I’ve also got a good stash of SR 4759.\u00a0 That’s been a favored “go to” powder for cast bullet loads and reduced .458 Win Mag loads, and I’m working through it at a pretty good clip.\u00a0 Trail Boss and 5744 are two powders frequently mentioned as also being good for reduced loads and cast bullets, so at some point I’ll have to start developing loads with those powders. I’m probably good for the next two or three years with my SR 4759 stash.<\/p>\n

The Results<\/strong><\/p>\n

To cut to the chase, here are the loads and the results:<\/p>\n

\"\"<\/p>\n

The Hornady polymer-tipped bullet was the clear winner:<\/p>\n

\"\"
Not too bad, I think. 10 shots with the Hornady bullets at 100 yards. I’ve shot tighter groups. I’ve shot worse groups, too.<\/figcaption><\/figure>\n

The Hornady polymer-tipped bullet put all 10 shots into a 3 1\/2-inch group at 100 yards, which is not too bad with iron sights and geezer eyes.\u00a0 That’s almost a 10-ring-sized group (the 10 ring on these targets is 3 1\/4 inches in diameter).\u00a0 I’ll call it close enough for government work.<\/p>\n

The PPU bullets are still available, although you don’t come across them very often.\u00a0 Sometimes the big online reloading shops (MidwayUSA,\u00a0 Midsouth, Natchez Shooting Supply, Powder Valley, etc.) have them on sale, and when that happens, I’ll stock up.\u00a0 Here are two PPU-bullet, 10-shot, 100-yard targets:<\/p>\n

\"\"
A 10-shot, 100-yard group with the PPU bullets.<\/figcaption><\/figure>\n
\"\"
I shot another 10-shot group with the PPU bullets because I forgot to chronograph the first 10 shots. Nobody’s perfect.<\/figcaption><\/figure>\n

Interestingly, the velocities of the two jacketed bullets (Hornady and PPU) were about the same.\u00a0 The Hornady bullet had a much larger velocity spread, but it turned in the tighter group.<\/p>\n

And finally, here’s the 10-shot, 100-yard target I shot with cast bullets:<\/p>\n

\"\"
A 10-shot, 100-yard group with cast bullets. These are much easier to shoot. Less noise, less recoil, and lots of fun.<\/figcaption><\/figure>\n

I was pleased with the cast bullet target, too.\u00a0 I wouldn’t ordinarily expect a cast bullet to group as well as a jacketed bullet, but these hung right in there.<\/p>\n

So there you have it:\u00a0 Three loads that return acceptable accuracy in a Mosin-Nagant.<\/p>\n
