I had good loads in my 12 Ga. using it for steel loads for ducks and geese along with Bismuth pellets.

It gets major fps in a 38 and 357 in short or long barrels.
I actually had to back off a 125gr JHP in my J frame snub nose
that was clocking 978 over my chrony !

I don't mind how it meters vs the good accuracy that I received
however it is a bit bulkey and fills the case fast but I have yet to
load a compressed load.

It goes "Bang". A good thing.
