[QUOTE="J E Custom, post: 1779279, member: 2736"] All chambers can be different, the tight(Minimum SAMMI chamber) is really no different than a large (Maximum SAMMI chamber) After proper sizing is done. Accuracy depends on how well the loaded round fits the chamber. Also the case life will be affected based on the amount of sizing required each time it is loaded. If you do a minimum head space the chamber will need to be monitored and cleaned more often for carbon and fouling buildup of chambering may become a problem at some point, Unless you change the sizing dies to compensate for the build up. (Not recommended ). I personally prefer the head space to be minimum for the first firing so I set it from .0005 to .0015 depending on the rifles intended use. on the more dangerous game I set head space to as Much as .003 for safety. I also size the cases each time they are fired to maintain the same head space .003. I prefer neck sizing only as long as the cartridge can be chambered without forcing it. When loaded this way, essentially the head space is .0000 . If cartridges have no head space the case will/can compress enough to chamber without effort. J E CUSTOM [/QUOTE]
