I played with the 100 grain XT's last year or awhile. But they always seemd to shoot 3 or 4" lower at 35-45 yards for me when shot against my Innerloc heads. They were accurate, and flew straight, but with all else being equal, they just shot lower, so I didn't use them, as I didn't feel like re-sighting.

don't know anybody who has tried them on a deer.
