Cnelk,
Where in northern CO are you? I muzzleloader hunt and have played with oodles of loads in a CVA Optima. I'd be happy to lend a hand if I can! I mainly shoot whitetails with mine though. I have killed a number of deer with 120 grains of Hodgdon Pyrodex and a 240 grain Hornady XTP bullet. Probably upwards of 8 deer. I have had a number of them drop where they stood with that load, and killed a couple deer to 150 yards with that load. Recently I switched over to 110 grains of the same powder, as not all of the 120 grain load seemed to ignite with CCI 209 primers. I also changed bullets to a 250 grain Hornady SST, those fly awesome and do a number to deer as well. The blood trails on the SST seem to be slightly better as well. What animal are you hunting?

I use 100gr of 777 pellets under a 240gr Hornady XTP for whitetails. Very accurate out of my woof, and I've had excellent terminal performance. This is all on whitetails, so I can't speak to performance on bigger critters. The woof is a great shooting rifle for what I paid for it I'm impressed! Good luck!
Just saw your post above. Looks like you found a winner! Good deal.
