Hi All,
Curious on your thoughts about my problem. First, the particulars: trying to develop a load that is accurate out to about 400 yards in my newly built AR....17" Lilja match barrel, 1:8 twist. The problem is this: I was trying to develop a load based around the 60 gr. Nosler Ballistic Tip Varmint bullet. Found two powders that shoot 1/2 MOA or better at 100 yard, but when I get out to 300 things go to hell.....the spread is well over 10". My thought is that it ain't the powder, because I've found two that bring the same results/problem, so in my mind is has to be the bullet/barrel combo. I can't imagine that a lighter pill would actually be more accurate at distance, and I don't want to go too much heavier either (it's mostly for coyotes and bobs, and I do want to preserve the pelt...so no gaping exit holes). The powders that I used were H4198 and H322. Your thoughts and ideas are much appreciated. Thanks.
