What you fellows don't seem to realize in your debate is that no crimp, even a roll crimp, is shorter than the difference between a 2 3/4" shell and a 2 1/2" shell. No loaded 2 3/4" shell encroaches on the forcing cone of a 2 1/2" chamber. Do you fellows even know what a quarter inch looks like? The Garwood reference shown in snipehunter's post says it all. There is no appreciable difference in pressure caused by the extra 1/4 inch of case. That's what Garwood said in 1964 and that's what Bell said in the Finding Out For Myself articles. So I'm going out and shoot my 2 3/4" reloads in my short chambered guns like I have for more than 50 years without event. I have not spent a dollar to have chambers lengthened in that time and don't plan to in the future.
