I have shot a few boxes of Cutting Edge, Raptors and solids out of 44 mag, 357mag and 45 colt. I could not find much loading data either but ended up going with my standard powder charges that I would use with cast lead bullets of same weight. No problems here. I am a fan of cast for handguns, but had the good fortune to be gifted a pretty good stash of Cutting Edge products so I have been shooting them some. Like the idea of the Raptors and the big ass petals that come off shortly after impact whilst the rest of the bullet continues on it's way. But I have not shot so much as a whitetail doe with one so can't give a great first hand field report on them. I have a feeling that they will preform pretty well as advertised.
