Does anybody have a good load for 7.62x54R ??

what gun are you using and what bullets do you plan to use? i'll check up on some loads in our Hornady manual
Mosin Nagant M1938 Carabine( not rifle )

I'm going to give you load data for the 150gr, 165gr, and 168gr bullets. if you want loads for lighter or heavier bullets, drop a line.
The book's (hornady) slightly old, copy right 1980 so there maybe newer info that i'm not privy to.
Thank you Curtis.
...The usual rule of thumb is to calculate velocity loss at about 50 feet per second with the loss of each inch of barrel. However, this may not be entirely true when using the fastest powders.
If loading a carbine-length barrel, the usual practice is to refer to published data, then select the fastest listed powders and build from there. One way of confirming that a powder is too slow, if in the middle-range for burning speed, is to note whether it has an unusually noticable flash. Extra-slow powders do not necessarily have much flash, and the faster powders will have a limited flash depending on a lot of factors. That flash amounts to wasted powder....
Another comment: the 7.62x54Rmm has a case-shape and capacity closely similar to the 7.62x51mm NATO cartridge. It is reasonable to refer to data for that or the .308 Winchester, in shorter barrels, for a rough guide to approximate performances. However, the cartridges are NOT the same, and in any question, the data for the original cartridge must rule. Safety first.
In closing: several years ago, I chronographed the same reloads in the Russian Model 91 rifle, the Model 91/30, and their carbine. The loss in velocity dropped from .30-06 performance to ordinary .30-30 performance. Again, about 50 fps per inch of barrel-loss........

I like the Sierra .311" dia 180 gr SPT bullets the best in my 91/30.
I have also used the Remington 180 gr bullets.
I can neck size the 7.62x54R cases by not resizing all the way. This is
Reloaded with neck sized cases, CCI 200, 2.843" OAL, and IMR4895 powder
I reloaded again:
I like Lapua brass much better than S&B. The S&B Boxer brass has two
The factory loaded ammo:
I have been getting the rifle on the paper with surplus ammo from
48.2gr. XMR 4350
41.5gr. IMR 4895
S&B case, REM primer, 180gr. Sierra (.311). Shoots great in an M39 and 91/30.
Suggest you slug your barrel to make sure which bullet to use .308 or .311. I've got a Chicom carbine that prefers .308 165 gr Horn BTSP and a Finnish one that is better with .311 Sierra.
I'm working up some loads for my M-44 that slugs at .316". I'm loading up some Speer 180 gr. RN with 42.5 grains of IMR4895, CCI 200 primers in once-fired Prvi Partizan brass. I'm hoping that the longer, slightly larger, flat-based bullets will stabilize better in the larger bore. I'm going to pick up some Hornady 150 gr. .312" PSP bullet at the gun shop this week for another recipe.
