Gun is inherited and very special, as such load development started. Walnut stock OEM.
I've been having really bad groups hand loads with IMR-4350, 4064 and 4320. Bullets Nosler 150 BTH, Hornady 139 SP Int and all four of the Hornady 162's. Barrel is 1:9.5 twist and 22". Going to try Varget next I guess. Still could be a hardware issue. Plan on ripping it apart to see what's going on. Also switch to a one piece scope mount/ring or extended tactical base. Scope is a Vortex tactical 1" 4-12X40 I believe which also could be bad. Anyway had trouble getting on paper at 100 yards, went to 50 yards and get 2"- 4+" groups. It has a short box so I lightly Lee Factory crimp at the cannelur. Still didn't mater when I worked on the jump either. Hornady brass and Win.
Ideas on a load, maybe I'm in the wrong realm to start with. Thanks!
