I have never used the .30 220 Partition on game, but have been using the 200 since it was still lathe-turned, back in the mid-1970s. Have never taken dangerous game with the 200, but have used it on several elk from the .30-06, and the .300 Winchester and Weatherby Magnums. Have yet to recover one, though one did stay inside a bull after a rear-end finishing shot from a .300 Weatherby at around 375 yards. Traced the wound channel into the chest cavity, but never found the bullet.
Also once put one into the left shoulder joint of a 6x6 bull, quartering toward me at 75 yards in thick cover. It exited at the right rear of the ribcage.
