Great question. I love shooting my Ruger 10/22 topped with a Nikon 3-9 BDC scope. I can use Nikon's Spot On program to dial in my BDC reticles to my desired distance.
I just had an opportunity to use Nikon's new ProStaff Rimfire BDC150 scope over 3 days of sooting and I was well as about 160 other guys were quite impressed. Now if I can just get my hands on one to put on my 10/22 I can really air it out.
