I for one wouldn't like to fire heavy 3" cartridges through it as the recoil would be quite fierce I should think. Lagopus......

This Italian 20 gauge double has 3” chambers:

It weighs 6 1/2lbs, and might not be that bad with a 3” round, but, I’m in no real hurry to find out. 3” 20 gauge ammunition did not impress me when I tried a few, 40 seasons past. I didn’t try it in a sub 6lb gun, either.
