I live and hunt in IL and would recommend the Omega if you want a TC... it is legal to hunt with in all the firearm and ML seasons. If you were willing to entertain other ML's besides TC... Sabot chucker - the Savage 10MLII can be used in IL with smokeless powder in all three season (2 firearm and the ML)... I just purchased one myself. Conical chucker - White, any White ML... I took my largest buck ever at 185 yards with a 496gn conical, 85gn of T7 2f, out of a White Super 91 .504 caliber. Another good ML for accuracy is a Knight DISC Elite (I do have one for sale, I know shameless promotion).

I have hunted with a ML in in all the firearm/ML seasons here in IL for 5 years... would never go back to a slug gun. Accuracy and distance is why.

So if you like TC, you can use any model they have in IL.
