Picked up a McGowen 8" Twist pre-fit used--have no Idea of the round count. The chamber seems on the "Large" side as my Wilson dies will size without a GREAT deal of effort to remove fired cases.

It seems to want to shoot 70 Gr Sierra's BUT nothing in the 75-95 Gr Range well at all. The 70"s shoot well with N-135 and the 105 A-Max with H-4895. with BR 4's -unfortunately I all but out of them. I have 7 1/2-400,450 and Wolf Magnum's

Any suggestions for powder/bullet-primer combinations for the 75-95 Varget did not work with any of the bullets I tried of those who have the Mc Gowen bbl.

Thanx,
Jim
