I'm looking to scope a Ruger M77/22 standard w/sights. I have some Ruger medium rings. I am looking for a scope to mount on this for squirrel/rabbit/grouse hunting. Nothing super long range. I prefer fixed powers, but I'll do low-power variables. What do you guys have and what would you suggest? I've looked at Weaver Rimfires and Nikon Prostaff.
