Gunsmith P.O. Ackley came out with a large series of "improved" cartridges.
Mainly this involved moving the shoulder forward, shortening the neck, and reducing body taper.
The case would hold more powder, and you'd get higher velocity.
Given that when Ackley was active the .30-40 was still very popular and rifles were very available and cheap, it's possible that it is an improved round.
