My Dad shot a nice 6 point this past rifle season weighing around 180lbs at 15yds with his .30-06 pushing 168gr A-MAXs at 2900fps. He hit the deer square in the chest and it instantly dropped to its feet. After field dressing it, we found that the bullet passed into the chest cavity with a quarter sized entrance and blew up right in the middle of the boiler room. I know some guys don't like them and disapprove of them, but we have had excellent results using them in a pair of .308s and my Dad's '06. Kills were made out to 600yds on deer and groundhogs, all kills were DRT. At farther ranges, they went in, blew up and left 2"-3" exits. Seems like they do the job and dump all of their energy inside the animal leading to a quick, clean, instant kill! gun)
