I have used IMR4227 in my 686 6" with 38 special cases, just to see what would happen.

This powder is very slow in burn rate and reminds me of loading a 270 or 30-06
with the slow 4831 powder, which is a great powder for begining loaders, to keep them out of trouble.

In a 38 case with a 110gr JHP and a "Full" case of powder my revolver got 945 fps.
A 158gr lead bullet with the short 38 case maxed out at 888 fps, with 11.0c .

I had to stop shooting loads in my J frame snub nose, since the powder locked up the cylinder solid, to where I needed to get it home to dismantle it and clean it, to get it to work again.

Have fun.

PS;
it does work a lot better in a .357 case.
