My only trouble with Ballistic tips also happened with the 7 MM Mag. These were some of the early BT's One did the job but the other only made a big welt. The first one went in behind the shoulder, turned 90 degrees and came out the hind quarter. The other hit ther shoulder and didn't penetrate at all. The Ballistic tips have been improved several times since then and NOW IMO are amoung the best deer bullet out there. One should stay with the heaviest per caliber BT's for game bigger than deer. I also keep them loaded to between 2600-2800 fps.
