Cheap Russian ammo defeats the purpose of cheap Russian ammo.
That stuff had very poor quality control. In fact, a friend who had terrible precision with his Mosin pulled his ammo down and couldn't find a bullet or charge that weighed the same as another.
The exceptions to the milsurp ammo rule are 7n1 (near impossible to find now, and expensive) and Czech silver-tipped.
The rest, groups can be shrunk by at least 25% with handcrafted ammo. My Mosin is a working rifle and, as such, I require precision from it. I owe it to critters I dispatch.
This is the genesis for the mods I've developed and/or researched from the Finns, and the reason I only handload for the Mosin anymore.
