Oh man, you guys are great. I truly appreciate all this information. I've been reloading Xtreme 155 gr. (40 S&W). I run 6.0 grains of WSF, but that's about as low as I like. I happen to have a couple of pounds of WSF, Clays, W231, and Power Pistol on hand, so I should have no trouble finding a good starting load. I'll work my way up. 1,000 fps is my limit.
I've heard that Winchester primers pack more punch, so I should probably stick with CCI unless a recipe calls specifically for Winchester. I have no large pistol primers, so I'll probably stay away from Winchester (unless I find a specific recipe for it, or someone tells me my info about Winchester is wrong).
Once again, thanks for the hospitality.
