I have a couple of Remington 1889 SXS shotguns, one in 12 ga. and one in 10 ga. They seem to be very stout actions. These actions have 2 locking bites and a dolls head extension, would they be stout enough to mono sleeve (I think that's what they call it) rifled barrels into and make bore guns out of? Maybe to shoot round ball or short slugs? Both of mine are Damascus barreled but they were also made with fluid steel barrels....THANKS>>>Ed
