Its been a while since I tried them. Just couldn't get them to shoot at all out of guns that I know are subMOA guns. As John Barshness said in a recent article, they either shoot or don't shoot in guns. I believe him. Cause I know people that gets match accuracy out of XLC's. According to the article, if you have a gun that is a little on the worn side they might not shoot. I also found that. Or a gun with a tight bore, and another gun I was trying has a new Kreiger barrel, which according to my smith is notoriously tight. Well maybe. With modern screamers like 300RUM, I love the concept of barnes. I mean shoot it as hard as can, and bullet failure or fragmentation should be no problem.
