As I recall Sherman Bell found there was a slight bump up in pressures when the 2 3/4" were fired in 2 1/2" chambers, but it was only several hundred psi. When you start with low pressure shells it didn't raise the overall pressure too much. Everyone has to make their own decisions on what to shoot. When I shoot factory 2 3/4" in a short chamber I use Winchester low recoil, low pressure, AA shells in mine. They start off low in pressure and the recoil stays gentle on the wood.
