If it's an older gun - and a 2 1/2 inch or 2 5/8 inch 16 is - you also have to consider how these loads will affect the head of the stock. It's wood 70 or more years old. Running 2 3/4 shells through a short-chambered gun will guarantee 2 things - higher pressures and way more recoil. Excess recoil damages the head of old gunstocks. I'm betting that these bismuth loads are intended for waterfowl, so they're pretty much max loads to begin with.

Do you really want to subject your gun to that?
