Nikon has a Prostaff 5 3.5-14x40 BDC in silver but it's $319 and not a rimfire scope so no 50 yard parallax. I'm not really sure if the parallax is that much of an issue with a .22WMR compared to the .22LR though. Honestly if you are looking for a decent scope at half the cost of your gun you might be SOL. Those Savage's are pretty accurate rifles and considerably more expensive these days so when you consider 50% of what a comparable rifle today would cost your budget range for your scope increases significantly. If you look at like that spending $300+ sounds just right

I put a Nikon silver finish Monarch 2.5-10x40 BDC on my stainless Savage 116 FCSS .30-06 a couple years ago and they are good scopes. I think I have 3 rifles now with Nikon scopes on them, very good glass for the money.
