Funny you should say that...About to throw a spanner in the works, the 410 is a great little gun i have a couple, how about a hush power double barrel in. 20, the best of both worlds. A good all round cartridge, I’ll get my coat!!!!!!!
They tried to make a comeback here about a decade ago. I wish they had succeeded.My first gun was a Webley single barrel 16, affectionally known as the sweet sixteen, it was a lovely gun and the cartridge was the best of both worlds but not a common calibre anymore
