Folks, I have a Mosin Nagant 91-30 and a Mosin Nagant M-44. I want to develop a load that will work well with either gun.
Ihave slugged the barrels, but am not sure exactly what diamater I ended up with. The slugs were not completely uniformly round, and at the widest spot came in around .3095-.311.
It appears as though the 91-30 has a longer throat than does the M-44, but I settled on a Cartridge Overall Length of between 2.959 and 2.972 inches.
Is it safe to try and use .311 diameter bullets? I have heard that as small as .308 usually work well in these rifles, but I'd like to develop some hunting loads using the .311 diameter bullets.
My ideal load ( I haven't shot nor chronographed this load yet) would be 48 grains of IMR 4064 behind a .311 150 grain Speer #2217 Spitzer bullet.
I hope to try some of these out this weekend, starting at 44 grains and working up to 48, in .5 grain increments.
Does anyone have any other advice regarding load development for this round?
Thanks in advance!
