Winchester Ballistic Silvertips. First, there was a LOT of batches that had burrs all over the bullet. But even if perfect, the bullet performance is all penetration and little expansion UNLESS IT HITS BONE, then it is frangible as heck and acts like a hand grenade. I killed a lot of deer with them, but I tracked blood for elebenty nineteen miles without recovery too. Got rid of them and went to a bonded bullet.
Winchester Ballistic Silvertip from a 7mag @ about 40yds. I hit a fairly large MO doe square in the shoulder and the bullet blew to pieces. I found fragments all through the insides and from one end of the ribs to the other. Made a nasty bloody mess of things.
