Goose_Getter welcome to the world of muzzleloaders. I commend you on asking questions about a rifle you like now, instead of buying it and then asking is it any good...

The T/C Omega is an excellent choice for what you have described as your hunting situation. It is with out doubt one of the better long range black powder rifle I have read posts on. I own a Black Diamond XR and with the same barrel technically other then the action being different, this is a long range shooting rascal.

As m.t.hands was telling you, some of your best accuracy will come in the 100-120 grain range depending on the projectile you shoot. As for whitetail deer it is a 200 yard rifle if your willing to practice and have a good scope. Some of the loads I would suggest based on my experiences with the Black Diamond are the T/C Shockwaves or the Buffalo Bullet 375 grain SSB spitzer hollow point sabot. This even with 100 grains will floor any whitetail if you place it in the right spot.

As for moose, on a different board a person posted results of an elk hunt shooting Shockwaves and another a hunt for moose using Shockwaves. The wounds were hard to believe. These rifles do have the juice to make clean fast kills at long distances. The trick is to get the right bullet combination and practice. You picked a great rifle to do all of this with. A real beauty in my opinion. If I had not got such a good deal on the Black Diamond XR I was headed towards the Omega as my rifle. I am happy with the one I have (among many ) so good luck and good hunting.
