This was hornady's response to the use of AMAX on game. Note the gel test data... I don't see any reason that the AMAX bullets could not be used on coyoes and other small game. The bullets were disinged for match target but do have a lead core and the polimer tip to make it open up quickly. The bullets will open and fragment even on the small fox. We usuall see 15" in a geliton test with the fragnentation from 2" to the 15".
