After I do a partial(neck) or full length resize on some PMC brass, I notice the bolt closes with a little more resistance than what I normally feel from un-belted calibers. This is the first belted caliber I've reloaded for. Is this the belt-forward bulge I've read about? I can see a slight drag mark on the headstamp from the bolt face. I'm using a standard RCBS 2-die set, in a new X-bolt rifle. BTW the bolt will close with no effort on factory ammo. Thanks for your help.
