Mike, my "whitetail load" used the older double crimp groove 300gr XTP over 27.4grs of H-4227...ran approx. 1400fps from my 7 1/2" 454...its a slower loading compared to factory 454 ammo, but was a dream to shoot and the extra bullet weight allowed almost any angle shot from 100yds and under.....used it on 13 or 14 deer..

I came up on these two deer two years ago on a crop damage hunt. They were about 10 yards apart. I had my 7 1/2" FA .454. Dropped the one on the left in it's tracks with a 260 gr. Speer HP at 99 yards. The one on the right froze up, confused. The second bullet in the cylinder was a 265 gr. Swift HP. She dropped in her tracks at 102 yards. The damage from the Speer was 2 1/2" internally, and 3 1/2" internally with the Swift. These are the only two bullets I use on deer. I actually recovered 5 300 gr. XTPs from deer. My thinking is that if can't penetrate our smallish WV whitetails , then they're not for me. The Speer and Swift were total penetration.
