“What about a rifled shotgun barrel?
Do those exist? A shotgun is a smoothbore barreled longarm. I don’t think I’ve ever seen a rifled shotgun barrel.”
Yes, Virginia, they do. Of course, to be technical, a shotgun is no longer a shotgun once a rifled barrel is placed on it. If you get my drift.
Go to Remington.com and feast yer eyes on the deer barrels and such.
0.73” rifles are apparently an issue.....
