I recently traded in a guitar for a 1892 Eclipse Giant SxS shotgun. On the barrels it says Twist Finish, from what Ive got online it is another name for a Damascus barrel. Which means that it cannot shoot modern loads, now is it safe to shoot black powder loads, the guy I got it from said to shoot smokeless powder rounds, or is not even safe to shoot. Now my next question is in mounted shooting they use some reducers to shoot 45s out of it, now would this be safe to use it for that purpose. I just dont want to blow my own head or my horses off.
