My buddy that I shoot with competes in some long range challenges, like ones they just tell you the height of the target and you have to figure out the distance yourself, and round count and timing affect your score. He was impressed with it enough that it's on his list to buy.
He didn't need to spot for me, but he wasn't shooting at the time, so he did any way. It was kind of satisfying hearing him say bull, bull, bull, bull, bull, or same hole, same hole same hole over and over again. lol
For the scope on that one, I have a Nikon Prostaff 4-14, I don't believe it's their rimfire model, but it has a parallax adjustment down to 50 yards.
