That was Thunderbolt 40 grain 1255ish fps. I was aiming at the bottom of the white square, straight below the 3" ShootnSee bullseye sticker.
Except for my long range 22, I generally zero 22s at 50 yards. I bought this rifle to use with CBs or Quiet rounds for rats and such. If it were just a target rifle, that zero actually works pretty well, and it will zero out just shy of 100 yards. For it's intended purpose with such small targets, I'd like to get it dead on at 50 or even 25 yards. Its lots of fun to shoot and were 22 more plentiful, it would go to the range about every time. In late summer I got a box of 500 Thunderbolt just for this rifle, so I still have a fair bit left. I generally shoot less than 2 magazines per trip so 500 will last a while.
