I have the undertaker on my Moss 500 and it's ok, not great but I can put 30 pellets (5's)on a 9" paper plate at 40yds and I don't want to shoot them farther away. Mine is for lead only, check if you can use hevi-shot in yours, (not that it matters a lot, having a lead only choke saves me money since I'm not tempted to buy expensive shells)
