I mostly shoot paper, black walnuts, and grasshoppers with .22 LRs. Although I'm not much of a fan of ranging reticles, I have found that the Nikon rimfire BDC 150 reticle works quite well. i have the ProStaff 3-9x40 version installed on an accurate Ruger 10/22 22" sporter.
The flat trajectory of the 17HM2 makes it my first choice for shooting tree squirrels.
