Hi, I've found a good deal on drop in barrels for my Stevens 200 and I'm wondering if there's any reason I can't make my Stevens 200 shoot a pistol caliber, like 9mm, .40 S&W, or .45 acp? I didn't see them in the list of calibers thread.

Has anyone done this so far?

Will it take major fiddling/surgery to an existing bolt face?
