That is a pretty little gun. I just checked (again) RST doesn’t have any short ammunition for you, just yet.
You are not the first who has noticed that an English 2 1/2” 12 gauge is typically par with an American 16 gauge. Some of the English guys who post here will likely have more information on that name for you.
At the moment, I don’t have any “thin” wall shotguns. I’m too much of an oaf for those guns.
Just measured the wall thickness on a Halifax, 9” from the breech, they are .056”. Gun weighs about 6 lbs. A V19 20 gauge was .050 at the same point, it weighs 5 3/4 lbs. So, maybe they could be dented, but, I’d likely hurt myself in the process.
Use it in good health. Prices on guns like that in England are almost free.
Best,
Ted
