Black Hills 77grain Open Tip Match 5.56 x 45 designed for the M-16/AR-15 Rifle Designed for Special Operations for long range one shot kills. The MK 262 Mod 1 projectile is an open-tipped match (OTM) bullet, though it does not expand in the manner of a conventional hollowpoint. In fact, the hollow cavity is not there to induce expansion; it’s there to put the majority of weight towards the projectile’s rear so that it is more stable in flight and increase accuracy. Because it is not designed to expand and cause “undue suffering,” that critical phrase in the Hague Conventions regarding ammunition, the Navy’s Judge Advocate General Corps approved the round for use in combat. The same reasoning was applied to the Marine Corps 62-grain SOST round (MK 318), also an OTM design.
When the bullet strikes soft tissue, the heavier base comes around and causes the bullet to yaw, or tumble. The hollow nose cone breaks off and often the bullet fragments at the cannelure. This happens across a wide range of the velocity spectrum, which is why MK 262 Mod 1 proved effective in SBRs in addition to the longer-barreled SPRs. M855—or “Green Tip”—ammo was designed for battles with a body-armor-equipped army, hence the name “Penetrator.” On unarmored targets, it just zips through like it was designed to do. MK 262 was a better option for the enemy the military was fighting in Iraq and Afghanistan, though the round obviously does not penetrate as much as M855.
