since your post I did a little research, in the MZ season they are not legal(sabots) but in the rifle season they are. At least that's the understanding I get from the imfo. I have found. I chose to go in the rifle season but use my TC Omega partly because of the OTC tags but mostly cause I have killed lots of game over the years and have had somewhat of a rebirtrh into hunting since I began hunting with a MZ.
The only non saboted bullets I ever used and then it was in a .50 cal flintlock were the TC Buffalo prelubed @320gr. Do you think I could shoot them in the Omega?
like I mentioned earlier all I've ever shot in this 50 cal Omega was these pistol bullets and black hornady sabots the accuracy is superb.

Thanks for all the great imfo guys!
