"I don't know if there is a 32 short but those will all feed the LCR."
There is a .32 S&W cartridge, shorter than .32 S&W Long, but it's a little difficult to come by. The other choices are much more readily available. That's the advantage to the .327 - quite potent in its full power form, but there are many different other ammo choices. Sort of like the .357 Magnum revolver, which will also accept .38 Special, .38 Long Colt, and .38 Short Colt ammo (although .38 LC ammo is rare these days). I don't have anything in .327, but would probably snap one up if I got a really good deal, as I already load for both the .32 S&W Long and .32 H&R, all using .32 ACP dies. .32 Long or .32 ACP for fun stuff and .327 Fed or .32 H&R factory loads for more serious purposes. You have to be a little careful with .32 ACP as there may be extraction problems, and grouping may not be so good due to the slightly smaller bullet diameter, but it works OK for me. For revolver use, I reload .32 ACP with .312 lead bullets.
