I would check around gander is normally high, I like the 777 and it should be fine in the wolf, I was going to go with the pellets but it cost so much more and your stuck with the size you get.
I use 250 grain shockwave they work good in my tc triump and wacked a doe 2 weeks ago, I can cloverleaf 4 shots at 100 yards.
Might jump to the muzzleloader section for my info.
Also just practice practice and practice
