[QUOTE="CatShooter, post: 1306931, member: 7"] The actual pressure reached in modern cartridge cases, when used in modern rifles, is not important. There are three points where pressure can reach the mechanical limits and become a real problem. 1 - The head expansion (ejector extrusions, enlarged primer pockets, "Blown" primers). 2 - The Web (causing "Clickers"). 3 - The primer itself (true cratering). What the actual pressure is when you see these problems is of no concern - you drop the charge or go to another powder. The rest of the case acts like a semi-rigid brass "bag" to hold things together and make for an efficient delivery system. All the other problems with cases (head separations, primer flattening, case growth, splitting necks), are due to operator error, and improper FL sizing. Improper FL sizing is the number #1 cause of handloading problems, and short case life. [/QUOTE]
