I shoot .357 in my pistol and my Winchester 92 for my competitions. I use the same loads for both. I also have the 550B and get my heads from Northeast bullets. He makes a 9mm (147 gr) FP with 0.356 diameter. If you call him and tell him that you want the same heads with a 0.358 diameter, he will do that. If you ask him, he'll tell you that he does it all the time for the "Cowboy folk."
I like them because they don't have a crimp grove. My 92 is pretty picky and likes an OAL of 1.62, so with those I can set the head to what I want. I just put a decent crimp into the lead. I just make sure to get the soft lead heads.
