I'll have to eat a little crow on this one, as Parker Ackley very well did do wildcat versions of his own "Ackley Improved cartriges"
That being said, OKIE2, these cartriges (6-06 Ackley, or a 22-243 Ackley, 6 mm/.30-30 Ackley) are truly a wildcat. As such they have no factory chambering allowing the use of factory ammunition. They are based upon an Ackley Improved cartrige which has been either necked up or down from it's parent.
Sixtwoeightyfour, I had accidentally quoted your post instead of OKIE2's. I do apologize for seemingly calling you out.
