i have a 1923 LC Smith Trap grade with 2 1/2 chambers. I'll be hunting late season SD pheasants this coming December and was wondering if roll crimps will allow me to load 1 oz of #4's in a low pressure shell. I've used RST's with 7/8oz of #5's, but feel #4's are a much better choice for late season SD pheasants. Does anyone k is if I can make that work?
