The high FPS HS-6 loads locked up my action on the revolver, for some reason.

Cylinder would not open and the weapon would not cock.

Finally got things to work after tinkering with it and just had my doubts about the weapon, the rest of the test.

It might have been from a primer, or any thing but it did get my full attention, with this much fps out of a little stainless steel J frame.
It has taken a few hot 158 "FBI" loads and survived over the years.......
just that I don't like to over stress this great little revolver.....

and the word low FPS is an under statement on the bottom 2400 powder load.
It is almost 240 feet below the Federal factory speeds for a 2" snub nose !!
I don't know if 2400 will meet factory spec's with a 1.18" OAL, even with a full case of powder ?

Later.
