[QUOTE="PartsJr., post: 1583892, member: 87242"] If I recall correctly the original Parker Otto Ackley cartridge had a .004” crush fit when chambering a standard .280 for fireforming. The NEW SAAMI round has a .014” crush fit. BOTH are meant to fireform .280 brass. If you want to buy factory loaded .280 A.I. ammunition go with the NEW SAAMI spec. Just wanted to mention it because you might need to educate your smith in the event they haven’t chambered many Ackley cartridges. [/QUOTE]
