When I was a kid and I'm talking late 60's early 70's dad was always trading shotguns and revolvers. There's no telling how many Damascus barrels with 2 1/2 inch chambers I fired 2 3/4 smokeless loads out of. I don't recommend it however. I still have two Damascus barreled guns I have shot a lot. Everybody takes stuff their grandparents tell them as gospel. Truth is most of the time they're just repeating what somebody told them.
