[QUOTE="hawlejr, post: 2865352, member: 86290"] OK, I agree that FL sizing will solve the stuck case problem, ....but why? It seems that if you fire a round in a given rifle's chamber, that it would expand to fill the chamber under pressure, but spring back a little as the pressure relaxes, and then it would fit that chamber like a glove the next time. Furthermore, why on earth if it feeds OK in the first place is it difficult to extract? Where is the hangup? It seems like the chamber itself is ballooning more under pressure and then springing back more than the cartridge case to grip it so tight that it won't extract. Seems crazy to me. Anybody have a good technical explanation? [/QUOTE]
