[QUOTE="Mikecr, post: 1724039, member: 1521"] I'm pointing out that our reloading mob is lost w/regard to neck tension. Those merchandizing the latest gizmos for annealing are lost as well. What we have here is hoop tension, providing a variable force to grip bullets. There is more to this than simple downsizing. We have thickness variances, and shoulder angles contributing, and brass hardness, and length sized, and bearing area seated, and this -vs- that, etc. What we need to measure this is an instrumented collet system to measure a neck force which is countering expansion -to release a bullet. The collet system would expand a neck via hydraulics or pneumatics until a neck has reached a standard growth of say 1/10thou (bullet fully released). On release of pressure the neck springs back to that established with your sizing plan. This would then tell us we have a neck providing 22psi of grip, versus a mean average of 28psi (just for example). That's comparative, and you could calculate actual tension given xxx square inches of bullet area gripped. Someday we may have it, or we may never have it. With all the copying of products brought to market, and customer loyalty at an all time low, this is not viable to even develop at this time. The gains cannot equal the cost (right now). So for a long time past into future, we're stuck in a rut of delusion and disinformation. Very similar to the base to ogive (BTO) hogwash this mob wastes resources with.. You might wonder why I would refer to these situations as reinforced by a mob. Well, a mob is a gathering to group thinking. And intelligence drops with numbers. So when I see nearly everyone in a group declaring something consistently, while nobody in that group can provide any basis nor understanding for, I recognize it as the murmuring of a mob. Any single one of us in the mob is actually more intelligent than the mob as a whole. So never be afraid to think for yourself. [/QUOTE]
