I recently acquired my first two vintage 10 gauge doubles. The first is a massive English W.Richards hammer gun with 32" "London fine twist" tubes weighing a hefty 11 lbs/8oz. The chambers in that gun measure 3 1/4".

The second gun is a very early D grade Parker Lifter, with 28" Damascus Barrels, the gun weighs about 8 lbs. the chambers in that gun measure 2 3/4"

I think the English gun is way too early for 3" plus shells...

What ammo does the group think the two guns were designed for?

I love the look Hobbs, my Vizsla, gives me following my second miss in a row.
