[QUOTE="rscott5028, post: 687992, member: 24624"] PO Ackley did a bunch of testing in the 50's-60s with wildcats by reaming chambers such that the shoulder was moved forward and the angle changed to allow more powder and hence more velocity. In most cases, you simply fire-form the brass in your AI chamber using the parent cartridge. In some cases, you can purchase brass with the xxx AI headstamp. This was very successful and popular with some cartridges to the extent that we now have factory rifles and ammo for ones like the 280AI. In other cartridges, the difference was minimal. Lots of info if you google it... [url=http://en.wikipedia.org/wiki/P.O._Ackley]P.O. Ackley - Wikipedia, the free encyclopedia[/url] -- richard [/QUOTE]
