Just wondering if anyone could tell me the maximum cartridge length that will work in a model 57 or 657? I load 41 mag for my Blackhawk, but have a friend who has a model 657. We are doing some shooting together and I would like for my loads to be interchangeable if possible. I load my 210 grain bullets at an OAL of 1.58. I have a Keith style bullet that is longer and would like to use it, but am concerned that a loaded length of 1.69" would be too much. My friend is not in town to check his cylinder chamber length. Help!

Thanks guys,

Arminius
