I’ve heard that TC barrels are available in .45-70 caliber.Fire a few rounds then consult an orthopedic surgeon to repair the damage!
Think I would be better off slamming a car door on my hand a few times rather than touching off many rounds of .45-70 from a pistol.
Friend had a 45-70 revolver. He fired it 12 times with gloves, then set it aside as a safe queen curio. He said the pain was not worth trying to impress people.
