>>Any barrel damage?
I can only guess that the recoil is not as bad as a .50bmg or a .4570 Sharpes Buffalo gun, or is it??<<
I've got a rifled slug barrel on it. Visually there's no damage. Never shot either of those. Hits like a muzzle loader with no recoil pad on it. It hurts, heh. I've got a picture of blue shoulder after I shot 25 rounds one afternoon.
I have no doubt that it's one shot one kill. None. Specially if you hit them mid chest or higher. In a limb, the limb comes of, no question. Fun to shoot a few times just for pure shock value at the range. Usually get "is that a 10ga."? Heh.
Been some years now though. Don't know what the shelf life is one these, the ones I have are getting a bit older.

The .50 gives you a violent shove. The Sharpes is like getting hit with a hammer. A big hammer.
Take care and stay safe!!!
