Do you think a 7" twist is too much for 55 grain bullets?
Many years ago, I had a Mini-14 with a 1:7 twist barrel. I was hand loading varmint loads mostly with 50 grain bullets designed to "explode" on impact. These shot extremely well in my bolt gun, but when I tried them in the Mini I wasn't even on target. I moved the targets In until I finally figured out that the bullets were disintegrating in flight. I can only think that these super lightly constructed bullets couldn't handle the high RPMs of th 1:7 barrel.
55 FMJ or factory soft point ammo never gave me any problems.
