[QUOTE="Pdvdh, post: 1295552, member: 4191"] Outside neck turning reduced neck and seated bullet run out. I don't clean up the entire neck exterior. Around 50-65%, unless there's an abundance of neck wall thickness. I HBN coat all bullets. I lube the case neck interiors with Hornady Unique resizing wax. These steps all reduce case neck to bullet friction and grip/hold, and reduce the variance in case neck bullet grip between loaded rounds, IMO. However my 223 is an AR15. Mag lengths prevent seating bullets near the lands, and the slapping of the rounds into the chamber requires that the bullets be gripped reasonably securely by the case necks. So I purchased a LEE Factory Crimp Die and precision improved about 40%. Now my loads shoot better on paper, and are more reliable in function thru my semi-auto. It's rare to find examples where the LEE crimp die harms precision. I spent hours researching this. By and large, the folks pooh-poohing the crimping had never even tried it. Armchair experts. If the benchrest competitors didn't crimp, then it couldn't possibly be good. In fact some considered it pure evil. And they'd never ever tried it. Well how many of our LRH rifles are constructed for benchrest competition? And how is that argument pertinent / relevant, if my precision improves in my hunting rifles after crimping my best developed loads? [/QUOTE]
