"The purpose of the 7.62mm "open-tip" MatchKing bullet is to provide maximum accuracy at very long range. Like most 5.56mm and 7.62mm military ball bullets, it may fragment upon striking its target, although the probability of its fragmentation is not as great as some military ball bullets currently in use by some nations. Bullet fragmentation is not a design characteristic, however, nor a purpose for use of the MatchKing by United State Army snipers. Wounds caused by MatchKing ammunition are similar to those caused by a fully jacketed military ball bullet, which is legal under the law of war, when compared at the same ranges and under the same conditions. The military necessity for its use-- its ability to offer maximum accuracy at very long ranges--is complemented by the high degree of discriminate fire it offers in the hands of a trained sniper. It not only meets, but exceeds, the law of war obligations of the United States for use in combat.
One more thing:
The reason the US military uses the Matchking (I reload about 1000rnds of 69gr MatchKing EVERY YEAR) is that it's a more accurate round. When you pour and swage an open-tip bullet, you get more consistent results from round to round. FMJ is poured from the base, leaving inconsistencies in the bullets. The open tip of the MatchKing is considered minimal and not a "wounding mechanism", which is why the US Army Judge Advocate General (JAG) has approved them for use over existing Hague protocols (which we observe).
The reason the BTHP (Boat Tailed Hollow Point) doesn't fragment like FMJ rounds is that the base is jacketed, leaving very little from for the pressed lead to go. The base catchs the force and holds it together. In an FMJ, the lead is free to fragment and bleed out the open tail. However, when either of these rounds hit a brick wall, they shatter without fail.
But really, I don't think you'd know the difference from FMJ and BTHP, so why bother.
Just .. Go away.
