RE: 140gr bullet 7mm Mag
3of the last4 whitetails I've shot were with 140 BT's. One was at 200 yards, the other 2 at 325 to 330yards.2 dropped in their tracks, the other ran about 30 yards with a 3" exit wound (hit a couple of ribs and the liver). I think the Accubond's should hold together and perform as well or better than the BT's.
BTW, a friend of mine shot a large cow elk at 200 yards with a 140 BT a few years ago. Bullet hit in the boiler room and passed all the way through. Dropped her right there.
