Finally found a load with 77 tmks that this shaw barrel likes. Xbr, tac and cfe all shot terrible, varget was better but slow. Finally got a pound of Lever a week ago, that seems to be the ticket! 25 grains at 2.375 OAL, 2730 fps. 10 rounds into 1 3/8”.
Eight inch gong at 375 yards. Prone with ammo can and bag front rest, bino harness in the rear. It’s amazing what you can do with these 5x microprisms!
