I am thinking of loading up either some 68 gr Horn HPBT or some Sierra 69 gr BTHP match bullets. What velocity should I be striving for to obtain good fragmentation at under 150 yards? What powders would you recommend. I have a colt 20 inch 1/9 twist. Is there a section here to post relaoding questions? |
Such as this one www.ar15.com/forums/forum.html?b=1&f=9 I think 69 is pushing it a bit for a 1/9 twist...someone correct me if I'm wrong here. I shoot Sierra 69grain bullets except I have a 1/7 twist. I use Varget powder, CCI BR4 primers, and winchestor brass and I get really good results. |
