Hi guys. I am seeking advice on a mold for my Dan Wesson .357 mag. I would like an accurate boolit that I can load hot. I'm not sure if I need gas checks or not, but that's part of why I'm here asking advice. I prefer a Lee mold, as I don't have handles for anything else. If you have a used mold I could buy, that's would be good also. Thanks for any sugestions.
