The late Bill Curry and I had our 32 ga Poli shotguns proofed for 70mm-2 3/4" 32 gauge. I have my proof house certificate.
I don't know how many 2 3/4" 32 gauges there are in the US, other than these 2 guns.

I have heard that there is ammo in 2 3/4" 32ga in Italy. I thought it would be fun to have brass hulls made up. 32 is about 50 cal.

Imagine a 2 3/4" 32 ga brass hull with a big wad of lead on top of a full case of 4F. It might act like an old British black powder express cartridge. I may yet get around to this.

All Best,

Joe

PS The 24 ga Bayard barrels went on a 28 ga gun. Kirk Merrington did the grafting. The 32 ga found a different home.
