Many years ago I bought an RCBS die set, marked 45ACP Shotshell, off the markdown table at a shop. Set came with a form/trim die to cut down 308 or 30-06 brass and to form a shoulder for the basic case. The single sheet of instructions that came with the die set were very basic with no load data. However I did find several detailed magazine articles from "The American Rifleman", "Guns & Ammo" and "Combat Handguns" that provided excellent load data. I did find that there was a trial and error process for getting the final trimmed case length correct so that a FIRED case was short enough to allow it to clear the ejection port of a 1911 and Glock 21. When finally completed they worked pretty well on tomatoes that I used for test subjects.
