Great shot. JLA would be proud of you. He is into long distance .22 shooting.
CCI mini-mags have a good punch and I like them. I went to my fire arms dealer to get more a month or so ago and all he had were CCI AR Tactical come in a bulk cardboard box of 375 rounds), which he said were replacing the mini-mags. They shoot OK. I did some comparisons between CCI Mini-Mag and the AR Tactical on this post...
