Shooting magazine has a test of the new Hornady bullets.
The rubber tipped 265-gr .444 shot flatter than their regular FN 265, but the old one had more weight retention and penetration, just as one might expect. The regular .444 is already a 200 yard rifle for deer, elk and the average black bear. If I only had one rifle, the new bullets might be interesting, but for me, the .444 is about power inside 150 yards.
