When you say 3 3/4" is that to the end of the chamber or the end of the forcing cone. Is this a 2 3/4" chamber with a 1" cone?. I assume those .200+" chamber measurements are taken at the Breech end & not the forward end of the chamber. Often that is the most critical measurement of all, especially on a lengthened chamber.
