I can't find my data now, but I used an old NRA book handload for the 45 Auto Rim in 45 ACP using a 300 grain flat nose bullet and Blue Dot. Would not chamber in the 1911, but fired nicely from my 1917 and my 16 inch barrel Tommy gun.

I'll have to go through everything again to find all the data, but it was a superb Tommy gun sub sonic round so I was planning on doing it again. Forgot the bullet, and I think the charge was 7.3 grains of Blue Dot, something like ~730 fps in the revolver and about a perfect ~950fps in the Thompson. It shot high in the revolver, and was a BIG gentle push. I'm sure the N frame with that low pressure round was just fine, and the Tommy is overbuilt that the high recoil shouldn't hurt it.

Probably overkill for bowling pins though, or would it be ideal?
