.......bronko is right...this really belongs in the "blackpowder" forum. But I, too, will offer a little advice here... I shoot a CVA Wolf inline when season allows here in PA. I've tried 150 gr. of Pyrodex in it, just because it's capable of handling it. Aside from loosening several molars and causing my eyes to rotate in opposite directions, I quickly went back to a 100 gr. load that shot goooood in my gun. The 150 load opened up dramatically, and just beat the livin' bejeesus out of me. Nooooo need for it here on a whitetail or black bear...period.
