I found this site with some different loads for 7.62X54R ammunition.
I will most likely be shooting a Mosin-Nagant M44

Are these rounds too powerful for the M44?

Hornady SP 123 grain bullet
.310" bullet diameter
2.654" overall cartridge length
BL-C2 Powder
55.6 Charge
CCI 250 primer
3323 muzzle velocity
3017 muzzle energy

I think you're ok. For my M44 I've gone up to 56.0 grains of BL-C(2) under a 125JSP bullet and OAL of 2.715" (to match cannulure in bullet) without problems or pressure signs. This using 0.311" bullets. I worked up from a starting load down around in the upper 40s if I recall correctly. Winchester and Federal LR primers.

Caveats- have you slugged your bore to verify you can use 0.310 or 0.311" bullets? Should be ok but IIRC you want to make sure you don't somehow maybe have a Finn Mosin that's 0.308" Don't know if there are any Finn M44s but that's one thing good to do.
 
Thanks for the input. Mine is a Russian make. I already Slugged it and it will accept the .310". Many sites say the barrels vary from .310 to .314 for bullet fit and they were aiming for .310" with the design. Guess I got a good gun? Groupings will tell the tale.
 
I don't know about the powder you've asked about, but just doing a quick eyeball of Hornady's data for that bullet it looks to me like you're going to be about 200 fps faster than any of their "max" loads. It's possible that the powder gives you that but I think i'd probably back off of that load as a starting point. FWIW.

Have a good one,
