It's funny the different experiences we have all had. I've used 130 gr ballistic tips in my 270 since 1986 and never had one not exit and leave the insides like soup. For the hell of it I worked up a load last year with the 140 Hornady spbt which is supposed to be a harder bullet. Shot a buck at about 20 yards in the chest and it did not exit, which surprised me. I killed a nice 10 last week in AL with a 7-08 and 162 amax going 2650fps in a 20" barrel. Hit the deer right behind the left shoulder at about 40 yards. Exit was right side liver. Bullet hole sized entrance and exit. Not alot of internal damage and zero blood trail. Deer went about 100 yards, but was by the grace of God we found him. I've read hundreds of accounts of that bullet being great and/or explosive, but it sucked in my one experience with it.
