one thing to consider when your purchasing a scope for a rimfire is the internal MOA adjustment. I purchased a nice little bushnell 6-18x40 for my 10/22 with in your budget but ended up having to sell it. alot of higher magnification scopes have less elevation adjustment and are more suited for larger calibers with less bullet drop, at 100 yards i was maxed out bringing the crosshairs out of the sweet spot in the lens. almost all companys will mention the scopes adjustment range at 100 yards on the websites. im not an optics guru by any means and i know there are many high power scopes for rimfires that work quite well just sharing what did and didnt work for myself. i only look for scopes with atleast 80 MOA adjustment at 100 yards.
