I don't fire corrosive/surplus ammo outta my MNs. Nothing wrong with it (as long as you clean/scrub them out same day you shoot it) but I think you can't realize the full potential of them "Russian Mules" unless you use factory or make your own reloads. Not trying to be a snob and someday may change my mind, but for now I'll shoot the "Good Stuff".
Does anyone besides me reload for their MNs on here?
I tried some 174 grain privi partizan BTHPs at the TX Shoot the other day. I used 41.5 grains of Varget powder, which is a low end on the data scale load which runs from 39.6 to 46.2 grains. It proved to be a good medium/mild load with not so much thump as full loads, easier on me and the old guns. I was using H-4895 powder.
I didn't get to do any real accuracy testing, but just fired some the other day. I think I have a starting point for further evaluation.
I use .311 diameter bullets (same as for for the .303 British) because the Russian made rifles run from .311-.314, the Finnish made ones being closer to diameter (7.62) and those who reload for them use .308 diameter bullets with good success.
Old forum member "Pirate" has a nice collection of MNs, but I haven't seen him here yet since the crash.
