44... you did catch me there... TC never made a factory 50 cal Contender barrel AFAIK, but I know there are a few aftermarket barrels... ( I'd like to get my hands on a 50-70 barrel, as I have a worn Martini in that chambering, I could interchange light loads between the 2...
as far as the 50 Beauowulf, sounds as if the case is not strong enough for "normal" loads, so the Contender would likely be fine with light enough loads to get any kind of life out of the brass... that said, once you get to .501", you've approached the size limit of the frame, without doing something "funky"
but you got my general intention
