Indeed, so maybe the pellet shooter's roundel cartridge receivers are different to the BB shooting version, too? That would further explain why one model is designated as a pellet firer, and the other a BB, with the anomaly that the pellet cartridges will work in the BB guns but not visa-versa?
Also, Arthur, have you actually seen these Schofields in the flesh, yet, as the livery with the faux ivory handles isn't a false patina as with the antique finish Colt (which I also like btw), but rather an even nickel finish, but with a dark and even hew to it which oozes quality and looks superb, which was why I bought one.
