If you reload "low pressure" 2 3/4", remember to build in an extra safety cushion. Per Bell's tests with long shells in short chambers, reported in Double Gun Journal, the extra length of a 2 3/4" hull in a 2 1/2" chamber can result in a pressure increase of 1,000 psi. It's a bit harder to get really low pressures with a 20ga than with a 12ga, but there are recipes out there. And given the weight of that gun, if you're shooting targets, you'll probably really like 3/4 oz reloads. Easy to do with Claybuster's 3/4 oz wads.
