I've taken dozens of deer with this bullet with excellent performance around the 2000fps MV mark from 20-338 yards. The only ones that failed to exit (2) were around 200 yards, went through both shoulders, and the jackets got caught up under the offside skin, one lead exited and one did not.

Last year I pushed these same bullets to 2770 fps MV in a gun built for smokeless powder. At about 150 yards I still got a pass-thru, and the impact velocity was still way above the MV on a blackpowder rifle. At only 20 yards the bullet was a grenade and blew the sternum off the deer but vaporized.

Moral of the story: At blackpowder velocities it is an excellent bullet. If you've going to crank it to 2700+ fps keep the shots over 100 yards.
