[QUOTE="bigedp51, post: 1131343, member: 28965"] You have two choices 1. Increase your neck tension by making the expander button smaller or using a smaller neck bushing etc. 2. Lightly crimp the case mouth, the RCBS AR series dies I have use a taper crimp which I prefer. We live in a plus and minus manufacturing world and no two dies and chambers are the same. Meaning neck tension can vary by the type/brand of dies and the neck thickness of your cases. (brass springback) On my AR15 rifles and my M1 Garand I have never had a problem by "NOT" crimping "BUT" my expander buttons are polished .001 smaller. But on the ammo I load for my two sons AR15s I use a type "M" die expander and a light taper crimp. Bottom line, make test rounds and see if you can push the bullet into the case by placing the bullet against your loading bench and pushing on the base of the case. The simplest thing to do is buy bullets with a cannelure and apply a light crimp if you can't measure your neck thickness and expander button diameter. [/QUOTE]
