Best 22LR scope

I mounted a NF 15-55x52 on my Kidd Supergrade.

For what you are doing the original Nightforce Benchrest scope is the ticket. I have owned several and they are excellent especially considering the used market price.

I'll vote for our ZC840. 40X maximum magnification, MPCT1 reticle for what you asked, close focus of 15 meters, internal elevation range of 28 mils, and the finest optical performance you can ask for. Hit me up if you need more information.
