There are also versions that use the 44 mag, 45 colt, 454 Casul, and I think 50 AE cases necked to 357.
But they would be best out of either a single shot handgun or carine like the T/C's or the Handi rifles.
But I think if you are going to go with one of the wildcats there is nothing that 357 Max or 35Rem won't do, other than get rid of some 41, 44, 45... Brass. I always thought a 308X1.5 would be neat opened to 35 cal and then realized it was basicly 35 Rem.
the 50 and 44 versions could be used in an Auto like the Desert eagle if that is your goal.
I remember a 45Acp version to give almost what 357 mag did out of a 1911. Kind of the pre 357 sig round.
Bottle neck rounds do not work so well out of a revolver. Since this is a general Handgun question and not T/C specific Thought I would toss it in
