Hello, a short list of 41s I already shoot. 41, 41 special, 41 Magnum, 41 GNR, 41GNR #2,411JDJ,411JdJ short,41x375 H&H,41x460S&W,41X500S&W,41 HAWKS, neck on the 405 has to be size down just a little got that one to. There are a couple more that I've left out because honestly, I would have to look at my dies to see what they are. As you can see a couple of them that you mentioned. I have already made "do not try to put the 41x460 or the 41x500 into a contender or encore unless you really want to destroy them" and possibly injure yourself.Do not ask how I know this. They will work in a Ruger number one. A reputable gunsmith will not chamber these two rounds.
Really, just wanting to add another one to my list.
I thank all that it read and responded for your input.
