I have a custom rifle and trouble getting a good group, I check the twist seem to be 1:10.5. What Im reading the slower twist may have to go to lighter weight.If I do the greefell cal. need a bullet length around 1.4, Im I reading this right. Thanks
I need some advice with my grouping accuracy . I have 140ab with rl22 and 168vld with h1000 they both shoot 3/4 groups at 100yd but at 200-300 they spread 21/2 at 200 and 6inch at 300, any suggestion.
