Pro: you can use it against snakes more effectively than snakeshot out of any other revolver

Con: I read one review that said using semi-wadcutters was not easy because of the gap between the ramp and the end of the bullet is like an inch and it doesnt feed into the barrel as easily as a roundnosed round would.

And good luck finding any non-slug shotgun shells other than skeet rounds in 2 1/2 inch 410 shot shells.
