i am thinking of taking my current scope off of my muzzleloader and putting it on my shotgun since i got a rifled barrel for it. the scope i have now is actually a shotgun scope. i was looking at getting the Simmons 3-9x40 ProSport Master Riflescope for my muzzleloader from Dicks Sporting Goods for $70. Do you guys think this is a decent scope or am I wasting my money, and should look at other options. By the way, I'm looking to keep the cost under $100 if possible, w/o mounts and rings.
