Discovered the 45 ACP hack when loading 44-40, was a bit surprised to see it as a published hack.

BTW, it works well.

Like Brian above, I use a 10mm fired case to measure my 308s instead of a 45ACP because 10mm/40S&W are closer to the specified datum diameter. In fact my fire formed 308s measure 1.634″ with this case, which I believe is bang on the cartridge spec.

Yes it was my tip, and it is fun being famous but I chose to use a case that lands closer to the middle of the shoulder such as a .38 special. The .45 variation was the site owner/editor/chief writer’s idea, one that I have not tried. Sometimes dies modify the radius at the point of the shoulder so that the change there, from sizing, may not correspond exactly to that which takes place at the datum line. The thing about this that I like is that it gives a new reloader a tool with which to measure an important dimension for almost no cost.
