The Schofield revolver can now be used with pellet cartridges. It still has a smooth bore for BB's though and the maker resists requests for a rifled bore.
What's accuracy like with pellet or BB?
My old Benjamin pellet pistols will hit a coffee can at 50 yds 100% of the time.
My old Healthways Plainsman BB pistol with its smoothbore will hit 50%, despite an awful DA trigger and crude sights. Impressive!
My Remington M1911 BB pistol has a hard time with a soup can at 10 yds, but I like it for its authenticity.
So how does the Schofield stack up?
BB Pelltetier went pretty in depth with one.

I'm quite happy with mine. I filed the rear sight notch just a hair wider and hit it with some alumablack, and it's probably my most accurate bb pistol. About a 90% hit rate on 1"x2" fir cones out to about 20 yards. The black bb's seem to shoot the best of the three types I tried, I'm really temped to use a pin reamer to open up six of the cartridges to take pellets.
