[QUOTE="BallisticsGuy, post: 1585813, member: 96226"] .253-.224=.029 .029/2=.014.5. Nominal brass neck thickness is from .010-.012. So you'll have ~.002 total clearance. What it's telling you is that it's got a pretty tight neck but you won't [B]have[/B] to neck turn. You will probably also find that your necks last a long time. The 0 freebore means it was basically meant for light bullets. You'd need a longer freebore to run the heavies but that has light bullets jumping across a canyon. The last chamber I had set up like that had my fired brass coming out with the inside diameter exactly at bullet diameter so there was extremely little working of the brass during neck sizing and my brass lasted a very long time.
