OK guys, she ain't pretty - but she shoots and she's cheap.
This is a TC .50 caliber 15/16" Hawken barrel for $60 plus actual shipping cost (see pictures below).
I acquired a Hawken a couple of weeks ago with the intention of selling the barrel and keeping the stock for a GM barrel I have. So I decided to shoot it before positing the barrel for a "full disclosure" ad. I shot two five-shot/50-yard groups out of it last Friday, one with patched balls and one with 250 grain XTPs in sabots. The targets are below,along with a picture of the patches I was able to recover(keep in mind that I'm a terrible shot with iron sights ).
I edited this post twice trying to get the last two images to show, but they won't. They will show for me if I click on them, so try that. They are pictures of the bore.
My wife says I'm totally nuts, but I think I'm Semisane.
