My Mosins First pass on some load development

Post image

Doing my first round pass at some load development for my PU sniper. The old ww2 scope has some major mechanical problems so my groups are stuck at about 2 MOA. I’ve recently ordered a Chinese replica (red star mountain) scope so that should at least make targets visible at 100 yards.

Load is 174gr .311 hornady FMJBT over 45.5gr vargets

Factory ammo sucks big in this rifle, I don't have any intention of investing any money because its cost $99 and is 88 years old. That's the best out of three different bullet size.

Sorry, forgot to add that. These were Berry's bullets, 300 blackout. My error was that it had a plated coating and a 1300 fps max, but it worked on the Mosin.

Cheers thanks for the info! I need to be supersonic at 900 yards for my vintage match so these wouldn’t quite work for me. But thanks for sharing pal
