So I thought, well, I know what I am charging it with and I do have a thrower, and fast scales... And it's all trimmed and sized... And a year ago I purchased heaps of 7.62x54R surplus ammo... Some of which I didn't feel safe with, so I pulled those and had the projectiles sitting here waiting...
So this is kind of the definition of plinking rounds
150gr surplus projectiles (more like 148, yes I did weigh them, yes, I am that pedantic), charged with 39gr of AR2208. Should be fun.
I load my 174gr with 43gr, both combination should be around 2400fps, so I even know what to expect. Kinda` cool.
