  Bullet construction can/will make a difference - all copper bullets are longer.

  Type of action has zero bearing. A longer barrel (24") might get you just enough extra velocity to move up one bullet weight in a 1/8 but it's not enough to make heavier bullets work in a 1/12.

  I shoot 77 grain OTMs out of a 8 twist 18 inch SPR with great accuracy.

  77g bullets should shoot great. They do in my 1/8 AR.
