50rds - 223 Black Hills 77gr. Re-Mfg. Sierra MatchKing BTHP Ammo Details

These .223 Remington rounds from Black Hills Ammunition are a great way to get ammo that is very close to Mk 262 Mod 1 specifications and performance but much less expensive. Each remanufactured round is assembled using a fired brass casing that has been inspected for deformities, meticulously cleaned, and then equipped with a non-corrosive Boxer primer. Crowning the cartridge is a 77-grain Sierra MatchKing projectile which bears an elongated boat-tail, a small diameter hollow-point (BTHP), and a military-influenced cannelure.

The toothed cannelure serves as a crimp point and prevents setback and jostling which could ruin reliability and accuracy respectively. A BTHP projectile’s overall shape resists drag in-flight for greater stability which contributes to remarkable precision. During construction, lead wire is spun through the bullet’s open cavity resulting in a core of consistent density enclosed within a jacket of pristine dimensions. 77-grain bullets are quite heavy for the .223 caliber and should only be combined with barrel twist rates of 1/7 or faster. While Sierra does not recommend the MatchKing for hunting purposes, it is a proven long-range round with many successful military records under its belt.
