I would suggest a High quality variable like a 2-7x33mmbecause your shots will range from Brush country to100 yards maybe a bit longer depending on your charge/load , I have a Leupold VX-I Muzzleloader scopeon my TC Omega whichonly ran me about$189.00, wheni upgrade
to a TCEncore Pro-hunter Hopefully this year i will be going for the Leupold VX-III 2.5-8x36mm. whatever scope youchoose GET QUALITY!
