Got my Charger about a month ago and i mounted this optic on top--
http://www.rapidreticle.com/22lr3-9x32.htm in Burris Signature rings.
Went to the range on a couple calm days, and tried some Rem. Thunderbolt ammo, and the bullets were keyholing the 100 yd. tgt. Kind of spooked me a bit so i went to the Stingers and shot 2 2" gps. at 100 yds.--better! I was getting 1450 fps avg. with 65 fps ES--not bad. I ran the calcs over Exbal and it gave the holdover for 200 yds. with the reticle (needed to use the 185 yd. mark for that range). There's a 12" steel gong at that range and i shot a couple 3-shot groups at 4 and 6". I was delighted about that.
Went hunting twice with it now and got a prairie dog at 135 yds. on the 1st shot and a jackrabbit at 105 yds.
Went out with buddy Mitch couple days ago and we got 2 jacks, 1 at 100 yds. and the other at 40. All these kills have been 1-shot so far.
Got to the range yesterday with it once more as i wanted to try the Quik-Shok and Velocitors. The Q-S shot into the same group as the Stingers, and held the same zero to 200 yds. again. Q-S seems to group a bit better than the Stingers too.
The Velocitors didn't fair quite as well, as the action and magazine was smoking when i fired it, and i got 3" gps. @ 100. No problem as i'll stick to the Q-S. Velocitors gave about 1225 fps. avg. Seems like i'm getting an avg. of about 200 fps less than advertised.
Trigger wasn't bad but i had my gunsmith install a Power Custom, and that seems to have helped some.
I installed a sling swivel stud in the bottom of the pistol grip, and use a tall Harris swiveling bipod while hunting with sling.
There r some rumors that Ruger will be coming out with a plastic stock for it, which will make it lighter still-- about 5-6 lbs. now with sling/bipod.
