As one that formerly performed warranty service and repair for Remington (in the golden years), the SP10 is one of the best shooting Big Tens around. Recoil reduction is paramount, and the big Green does the trick.
Why anyone would want a fixed breech Ten is beyond me. (whew)
Until geese get bigger, tougher, faster, smarter and start wearing flack jackets, I'll continue to use a 2 3/4" 12ga.
Don't know about a 10ga in an O/U, but there are 10ga SXS guns floating around, mostly older Spanish guns. In as much as most of the cheaper and older Spanish guns were known to double, I would probably load one shell at a time.
Richland model 810 is what I have. These were made in italy and back in theh lead days this gun had no equal. It is a double trigger O/U ten ga mag. That said I also own two SP-10 Remingtons and I suggest you buy an SP-10 Remington. A remington SP-10 with steel shot kicks like a trap gun. When the Superblack eagle benili's came out and all my buddys bought them they couldn't believe the diffrence in recoil between my Remington's in 10 ga and the 3 1/2 inch Benili's. Not only that the Big tens reach farther. If lead were still legal I would buy a Soft Touch or a g-Squared and put it on my Richland but with steel loads being only 1 1/2 or so the SP-10 is just a joy to shooot. I have shot 2OZ lead loads in it and they kick but nothing like they do in the O/U 10 mag. Jeff
I think American Arms made a 10 guage O/U. I saw one several years ago in a local shop. I have a Browning BPS. Great gun. Every year or so I load up some lead loads and shoot a round of trap with it. Great fun to watch the fire shoot out the barrel over a foot during night shoots.
Yes We had a American Arms 10 O/U still see a few of them they shoot nice not terrible on recoil I would guess you should be able to find a used one 400-550 range . I have since put my dbls away and went to a Br Gold 10 love it! Also went to a terror chocke on it and shoots awesum!!!
