I have a Mini-30 and load my own ammo. I have been able to develop a low-velocity (subsonic) load using 190 grain bullets, which I found to be very accurate at 50 yards, but they won’t stabilize out to 100. What I wanted was something to shoot armadillos in the yard at my farm place at night without disturbing the neighbors. It’s interesting that a round like this, at 1100 ft/second, retains nearly all its muzzle velocity almost out to 100 yards with the high ballistic coefficient of the 190 grain spitzer bullet.
Is the accuracy your getting from your Mini30 meeting your expectations? I’ve heard that accuracy can be lousy with these guns is why I asked. I have an SKS and an AK so I really don’t need another 7.62x39mm gun, but would have considered one if the timing was right.
