Winchester Platinum 260g
Twild provided these 45 caliber bullets. They measure 0.451".
The roll of tape on the second jug was removed before the shot. The range was 25 yard. Powder charge was 80 grain Blackhorn. The bullet went through carpet, plywood, completely blew up the first three water jugs, poked holes through the last three, then went through the phone book. The trap failed to capture the bullet. Photo shows the exit on the back of the phone book.

A .45 caliber sized hole through and through a whitetail, especially through the lungs, would leave a viable trail. I would like to see some expansion though. That would probably be a great large bull elk or moose bullet. Little on the tough side for whitetail it seems from that test.

From Chuck Hawks
The 260 grain Platinum Tip features a hardened, swaged lead core with the addition of about 2-1/2 percent antimony. This is the hardest lead that Winchester's swaging presses would smoothly handle. The bullet's silver colored "Platinum" jacket is one of the thickest I've seen on a muzzleloading bullet, and it features a very deep hollow point and has an exposed lead base. It was designed and tested to be the "ideal" muzzleloading deer-hunting bullet. Winchester consulted with MMP, and found that the HPH12 sabot, which appears overly long for the bullet, gave the best accuracy from their ensemble of test guns.

Just like the 44/45 300gr XTPs are different, its likely this one is also. This one is designed for 454 Casull which is faster than a 44Mag. Other than the color im sure their quite a few differences. Even the 45cal XTP MAGs are quite different in construction. The 240gr for example has a far thicker jacket than the 300gr MAG.
Im actually really surprised that this bullet appears to have failed to expand or at least very little. That load should be close to 1600fps or probably more.
