[QUOTE="Andrew Massi, post: 2372593, member: 106096"] The 284 case may show that if bullets are seated into the powder column also the 284 win was standardized around a semi auto (model 100)and lever action(88) short rifle so that must be taken into account- those actions are considerably weaker and more pressure sensitive than a bolt.action(especially weatherbys six lug. A very strong action) .473 case heads have proven to be capable of exceeding 65k Manufacturers who wish to establish a saami cartridge get to set that psi rating, saami then tests it and determines if it's safe. When norma standardized the wildcat 6.5-284 they decided what psi rating met their needs(barrel life, brass life et el) nosler same for the 280ai. Weatherby developed a case that is capable of routinely handling ,65k psi and they gave that design to saami for testing. Saami merely approves their design as being reasonably safe in modern actions, bullets, powders et el. [/QUOTE]
