What caliber do you reckon it is 'or the bullets'.
I'm definitely no expert and was just wondering about how that looks like a separate round pipe inside the iron and looks to be a different metal. I've never seen a gun barrel designed in that manner and all the dug ones I've held they are one solid piece of metal. I hope I'm wrong, but doesn't look like a gun barrel I've ever seen before. As I said though I'm no expert on gun barrels so I would love to learn if I'm wrong about that.
