Watched a buddy shoot a deer with this bullet this last fall at 450 yards. Caliber was 300 ultra, velocity at the muzzle about 3350. Neck shot and about a 3 inch exit. Broke the neck, but was not dead center in bone. It was quite spectacular though. They were very consistant from 100 out to 1300 yards. I was impressed. I would say they acted a lot like a ballistic tip in the terminal performance area. Havent been able to get the 208's to shoot in this gun yet.
