Mine is a 26” bbl. Which factory ammo was using the 105?
Eagle Eye Precision. Frigging expensive. However it shot great. I did have to seat the bullets .005 in because it threw (4) consecutive 4+1 groups during my expedited barrel break-in...afterwards it printed (3) consecutive 5-shot groups between .390 and .438.
I bought it during the dry-up of 6 GT components...which just happened to coincide with my trying a 6 GT.
