A friend just sent me a factory loaded 168 gr. Winchester Ballistic Silvertip that he recovered from a mulie that was right around 700 yards when the bullet went through its heart. Went in between two ribs, through the top of the heart and smacked an offside rib, stopped under the hide. Interesting bullet recovery, no core, simply a jacket with a fairly large front hole, one ripped section of tip area turned back over. No doubt the core was nearby (unfound) and it did the most damage, there is not much weight to the jacket alone. Very little mushrooming took place. The plastic tip is gone and the core is gone, otherwise pretty much the entire jacket is there. Deer died quickly. Testomony to the "hawsom-killin' parr" of the mighty .308 Win. In reality it simply indicates that a relatively un-mushroomed bullet through the top of the heart - results in a fatal experience for the shootee. A second smaller deer at about the same distance had a complete pass-thru with the same factory loaded bullet. This further re-enforces my opinion that the .308 Win. is a 600 yard killer on deer, starts to poop-out after 650-700 yards. We seem to get superb kills out between 500 and 600 yards tho.
