I thought you had a muzzle loader shotgun, but then I saw the "12Ga mod choke".
FWIW, I use two (50gr) T7 pellets, and TC's "Cheap Shots" (240 gr Hollow Points) which come with black sabots. It shoots 1 - 1 1/2" groups at 100 yards, your Huntsman, may or may not like the load, but it works for me. If you have time, use BH209 and work up a load, or drop Busta a PM, he's really into the BH209 loads, as a matter of fact, you should probably take PHATINJUNs advice and do a search. I think he posted quite a few on this site. Best of luck, and congrats on picking up the Huntsman, I really think you'll enjoy it.
