I have the exact rifle, best I ever got it to shoot was with a 55 gr. v-max and a max charge of H-380, it did 1 1/4" at 250 yards, but it does need trigger work, working on finding someone to do it in my rural area. However I did once take 9 out of 10 crows at 380 yards.

If your going through hell, keep on going, don't look back, If your scared don't show it.
You might get out b'fore the devil even knows your there.
