Tested the Sierra 85 gr. JHPBT Gameking in water filled milk jugs last week. I reduced the speed to around 2,400 fps and shot them at 50 yards. The Gameking seem to blow apart but made it into the fourth jug.
Latter the same day I shot a 180 lb. buck at 200 yards with my 6x47 Rem. Double lunged him due to the test ran earlier in the day. He ran 30 or so yards with a good blood trail.
2 1/2" exit wound. Excellent performance for lungs but would shy away from big bones...
