I guess not. I had an opportunity to say OTM in a conversation today but I said 77 grain match bullet and Mk 262 instead.
It's really not a bad idea to say OTM when you mean a match bullet and hollowpoint when you mean a, um, hollowpoint. There does seem to be some silly legal difference between a hollowpoint projectile, whose opening is deliberately meant to promote expansion and thereby a larger, more destructive, and more painful wound channel, and an open tip match projectile, whose opening is just an artifact of the manufacturing process of extremely accurate bullets. The former bullet is a Bozo No-No under the Hague and Geneva Conventions, while the latter bullet practically has a papal blessing. The semi-famous JAG opinion is at
and as you might expect when the lawyer who wrote it was a Marine Rifleman, it reaches the right opinion to help our troops. The key passage is this:
"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."
So, take your "hollowpoint" bullets to war and shoot a smelly bearded man with them, and your aiss is graiss. But take your "OTM" Sierra MatchKing bullets to war, that's A-OK, because with that tiny opening, they are more accurate and less likely to miss. If they happen to tumble and fragment like tiny grenades, they didn't MEAN to. Tough tamales, smelly bearded (dead) man.
As you see, the real difference between hollowpoint and OTM is the same as the difference between a Michael and a Carmichael, a Dexter and a Poindexter, a Gerald and a Fitzgerald, etc. etc. I only work here, I don't ask questions.
