maybe i shoot too much gun, but when i shoot them with a shoulder shot from my 243 ai with 70 grain b tip at 3650 i blow rite through and do them in pretty good. some times i may get one better than the other. i am building a 22-250 ai for my coyote partner with a 1:12 twist looking at the 53 grain v max's at a high rate of speed. the one i am building for my self will out do the 243 ai ballistic wise with 75 grain or 80 grain bullets. i would like to take a few coyotes past my personal best from this past winter at 725yards.
