Cartridges Developed by P.O. Ackley

A (probably incomplete) list of cartridges developed and/or improved by Parker Otto Ackley. Keep in mind, the "Improved" cartridges could all be formed from standard cases, and firearms chambered for them could also fire their standard non-improved counterparts as well! However, other cartridges without the "improved" nomenclature, do not share these characteristics as they would require length and/or caliber changes.
