Ackley is the undisputed King of Improved cartridges and maybe of wildcats in general. He was active in gunsmithing from 1936 until his passing in 1989.

Ackley standardized the improved cartridge concept. What I mean by that is that he created a simple understandable headspace method for these designs.You will learn how to apply these simple principals.
