A coworker of mine is trying to find .45-70 rounds for his Sharps, and he is having no luck. It's not the standard .45-70 round, it's the special "cowboy" round that shoots black powder or a lower-powered smokeless. He has looked and can't find the ammo anywhere. Does anybody know where you can get it? If not, someone else from the office is traveling outside in July and will pick him up some, but the guy doesn't want to wait until mid-July to shoot his gun.
