Well, a pal O mine got me a pound of magpro and I guess I am gonna try to load some hornady 139 grain BTSP's and aim for 3200. They say with 75 grains you can get like 3270 out of it. I aint interested in anything over 3200 fps but I'd like to get right at it. They say that Magpro is specifically designed for short magnums. We'll see. EJ
