How far you shooting and what frontstuffer? I prefer at a minimum a 3x9 and it certainly will do for ANY shooting under 200yds. If you have a longer range muzzleloader then you might think about a 4x12 or in that neighborhood. If you swear by less than 150yds then a 2x7 will be fine. THATS why I say a quality 3x9 will fill about 90% of the bill.

Just my .01/2c,
