[QUOTE="J E Custom, post: 1578251, member: 2736"] The place to start is with a SAMMI belted head space gauge. It sounds like your chamber is not cut correctly because it should be around .220 from the case head to the front of the belt. Lately there has been a rash of factory ammo that is maximum length or more than the .220 and will not chamber. It is hard to measure this dimension on the case it's self so by verifying it with a SAMMI head space gauge it will tell you if the chamber is cut to short or the ammo is to long. i recently had an issue with some Hornady custom ammo that was exactly .220 (Maximum SAMMI length) and the chamber was .218 so it wouldn't chamber. All other ammo brands fit/chambered fine. Most of the time, belted ammo has a dimension less than .220 so it will chamber in any SAMMI cut chamber. This short dimension works well for those that re load because after the fire forming, it becomes a shouldered case if you only size enough to chamber. J E CUSTOM [/QUOTE]
