Have been shooting my 6.5-284 Bullberry 26" at 2900 FPS with a 120 Sierra spitzer bullet. I have been shooting Deer on Crop damage permits. Most all the shots are over 300 yards. Exit wound is very large. The Deer go right down. The more I shoot it the more I like it. Use to use a 300 RUM for this purpose, but now no where near the recoil. Haven't tried any heavier bullets yet, as I got the rifle for Varmit Hunting, but have found it is a great deer rifle. If the barrel goes I will get another, or see about a rechamber and re-crown if possible. Lou
