Well I have to vote against wisdom here. Normally I fully agree that big scopes on small rifles are an abomination and a sin against nature, and if the rifle was chambered for anything larger than a .243, that would be my opinion here as well. But if the rifle is to be put to use as a walking varminter, in addition to being a deer rifle, one can see that a bit more magnification would be advantageous for seeing small targets. I don't know if you'd find one for $500, but it's pretty hard to fault the Leupold Vari-X II 4-12X40. If purchased used, it would save you some cash, and sending it to Korth for a check up costs only the postage. Perhaps a pair of scopes, one a varmint scope, say a fixed 10X or 12X, and the other a low powered variable big game scope, say a 1.5-5X mounted in good quality QD rings that have repeatable zeros, is something worth considering, even if budgetary constraints take you a while to get there. If that makes sense to you, start with the scope you'll use the most.
