The 180 Ballistic Tip is one of the heavy-jacket BT's, or at least it has been for several years now. The heavy-jacket BT's act very similar to Partitions when they hit stuff, penetrating quite well.
The one I have the most experience with is the 200-grain .338, because it had the heavy jacket from the moment it appeared, over 20 years ago. Once put on into the near shoulder of a big gemsbok bull in Namibia, and the bullet broke the shoulder and spine, then went lengthwise through the body, ending up under the hide of the rump on the far side. A bull gemsbok is about the size of a cow elk.
