Thanks for the feedback. I'll tell my wife that the pic backdrop went over well. I've never fired the Super 10 that has the HRBP, so I can't comment about the difference in perceived recoil versus a kick pad.
The Super 10's are NID (New Ithaca Double) guns - not the earlier Flues model. And not to be confused with the later heavier Ithaca Magnum guns made for 3-1/2" shells. The Ithaca NID is an excellent design, similar to A H Foxes with a rotary bolt engaging a slot in the top rib extension.
Personally I'd rather hunt with a vintage 10 gauge like the Ithaca, than with a modern 10 gauge SxS that's compatible with steel shot. I'll use bismuth, Nice or similar non-tox for waterfowl, and regular lead shot for turkeys and predators.
A couple of final pics: This one shows the Super-X type shells these Super 10's were adapted to.
Next one shows an excerpt from Askin's excellent 1929 book,
Modern Shotguns and Loads, commenting on his test Super 10 after doing extensive velocity and pattern testing ..... "nearest I ever came to an 80 yard gun".
