My comment would be to measure the chambers. Dropping loaded shells into the chamber doesn't tell you much about the actual chamber length(to the beginning of the forcing cone). Shells are at least 1/4" shorter when loaded and crimped, than they will be when fired. You can buy chamber length gauges or make them for about no cost. I've made mine out of stainless steel rulers. Narrow them to the chamber ID and you have the advantage of inch markings already on the ruler material. Example, a loaded 2-3/4" shell will easily drop into a 2-1/2" chamber, proving nothing much.
16 ga. chamber should be about .732" at the muzzle end.
