That is some good shooting. I'm glad the primer issue is solved, or at least seems to be. I only shoot 110 to 130 gr with a 250 gr bullet . I don't shoot that with a 300 gr . Although with my GPH I have to shoot 110 with 425 conical for accuracy,
Even with 90 you should be able to turn that into a 200 + yard gun
The 45 should get a chance next , right? I'm looking forward to seeing what it does , especially with the dead center 260 gr.
Great shooting
