RE: Mini-14 in 6.8SPC or Mini-30
That is a russian round,Bullet weights are around 100 to 150 grains..
Muzzle velocitys run about 2650 fps down to around 1800 fps depending
on your choice of bullet..If you get one,stay away from some of the older
ammo..They used steel cases and they will stick in the chamber..
Bullet dia. can be anywhere from ..308 to .312 is some of the older rilfes..
