.358 diameter with a Brinell of 12. I'm using 4gr of Unique for my 38spl, something light for targets. I'm picking up a SP101 that I have on layaway in a week or so and I'm on the lookout for a GP100 in more than likely 4".
So I havent loaded the .357mag yet but I'm ready to go. I want to wait until I get my SP101 in hand. I have other powders for the mag loads, probably go with 2400. I want to do some light loads for targets but no too light. I really should pick up some magnum primers as well but I think i could get away with the pistol primers on the light stuff.
