[QUOTE="Calamity, post: 2598882, member: 112048"] Does anyone know what technical criteria are used in design of the PRC cartridges? I assume it is for combustion efficiency, i.e., pressure curve, throat temp, etc., but it would be nice to know the details. Do they use a standard powder? Bullet mass to bore ratio? As for the gripe about the belt, I would like to see a belt on the new cases. I like the idea of head-spacing at the head, rather than the sloping shoulder. The belt was one of the better ideas in cartridge design, and if it had never happened, and was introduced today, it would be considered a wondrous new design breakthrough and everyone would be after the ammo designers to put belts on their cartridges. Belt-less cartridges are so bland looking.😄 [/QUOTE]
