My Ruger Super Single Six is not picky but it really shoots Federal American Eagle 36 gr. Hollowpoints accurately. Though this is a cheaper round and it burns dirtier than some, it shoots very accurately and has been my go to .22 lr. for twenty years or more and has accounted for more dead creatures than any gun I have over a variety of ranges and conditions. When that revolver comes out, things die. That kind of performance builds confidence... Clean Break
