[QUOTE="Varmint Hunter, post: 109727, member: 313"] I shoot the 75gr A-Max's all the time in my 22-243AI with a 28" Hart 8 twist bbl. I have never lost a single one and am getting 3,670 ft/sec at the muzzle. Here is what I think helps (other than having a smooth bore and a good throat): 1. I load all of my bullets .010"-.015" INTO the rifling so that they dont slam into the lands when leaving the case. 2. I moly coat every bullet using the NECO kit. Moly coating bullets greatly reduces the stess on thin jackets that engraving causes. It also helps out with the 8 twist barrel which is harder on jackets than a 9 twist, which is all this bullet needs. My overall best group shooting the 75gr A-Max moly bullet and 48.2gr RE22 was .625" ******and that was @ 600 yards. [img]/ubbthreads/images/graemlins/cool.gif[/img] After nearly 1,000 rounds this barrel still does not dust A-Max bullets. It doesn't shoot as good as it did - but it doesn't dust bullets.
