The 3X-9X Vari-X II works fine on deer under 100 yards–and also works fine for shooting deer at 400 yards when mounted on, say, a .270. In short, you don’t need all that magnification. I’d look at a fixed-power “shotgun” scope from any one of several manufacturers. A 4X should be plenty, and you should be able to purchase one for $150.

I have a Knight Magnum DISC .50-caliber muzzleloader that I've hunted deer with. I'm thinking of mounting a Leupold Vari-X II 3-9x40 scope. Is this a decent setup for a muzzleloader? I'd like to know before spending $270 on the scope. The longest shots I'll be taking are 100 yards.--S.
