The 265 Hornady flat point bullet is THE bullet for the .444, The Hornady SuperPerformance ammo is very accurate in my .444 and the bullet performs great. It might be a little too much for whitetails - it would be perfect on elk and moose. I've shot a couple whitetails now shooting through 1" saplings and when the bullet hits the deer it just destroys them. The last doe I hit at about 35 yards after the bullet hit a thumb size bush left a fist sized hole through the deer, and she STILL ran, but the blood trail was 5' wide to where she dropped after a 30 yard run.
