I read a thread a few years ago that Kamo Gary started about seating Barnes deep to get them to shoot good. It worked great the three times I tried it. Basically, seat them to the deepest cannelure and work up. In other words the neck stops at the cannelure as if you were gonna crimp it. After the third go around with the same results, I'm confident I can get them to shoot good with minimal range time if the rifle is any good.
Thread was by Safariman. That's right. Sorry man.
