I picked up a couple of boxes to try them out in my 270 WSM. I have found that they group very well (under 1/4" at 100 yds). On game is a different story....1st deer shot at 40 yds, very small hole going in, baseball size exit wound. 2nd deer shot at 250 yds, same result, small in, big hole out. Shot a moose in the top of the hump in the spine, took an orange sized section of the spine out. Hydrostatic shock I have found it terrible, they make a huge mess, doesn't matter what animal or the range the results are the same..bloodshot.
