Thanks guys. And, yes Cabela's is generally high for used guns but I have bought a few at the Glendale, AZ store at very good prices. Just never know. The trapdoor is in used condition with a repaired crack in the forearm, what may be a new hammer screw and there is not much bluing left. Not sure what the front sight is supposed to look like but it may be a replacement. Rear ladder sight is original, trapdoor and reciever look very good.
From handling and inspecting the rifle I feel it could be safely fired. I have a lot of 300 gr bullets loaded up in front of 10 and 12 grains of Unique which, I think, should be a safe load.
