20rds – 223 PMC X-TAC Match 77gr. Sierra MatchKing OTM Ammo Details

These impressive .223 Remington rounds from PMC are built with long-range precision and competitive events in mind! As part of the "Match" line, this cartridge profile is assembled from quality components which includes reloadable brass casings, clean-igniting Boxer primers, and heavyweight Sierra MatchKing (SMK) projectiles. The SMK design comprises the lead core, gilding metal jacket, pronounced boat tail rear, and hollow-point meplat of most open-tip match (OTM) designs. Sierra does not suggest this bullet for hunting purposes as its hollow tip is the byproduct of lead-wire feeding which is used to guarantee a core of consistent density and weight as opposed to fragmentation.

At 77 grains, these SMKs are very similar to the venerable Mk. 262 Mod 1 cartridge which is issued to U.S. military sharpshooters in a 5.56mm NATO format. With or without the military-requested cannelure, the rounds are well-known for steady drag resistance and tight parameters which contribute to deadly accuracy at extreme distances with a high ballistic coefficient. PMC is headquartered in South Korea and derives its work ethic and designs from a self-sufficient military ammunition program that controls all component quality on site. While they were once known as high quality import in the United States, they now produce many of their cartridges in Texas using locally sourced materials and expertise.

Due to the heavy projectile weight of 77 grains, it is recommended that these rounds be used with a barrel twist rate of 1:8 or faster.
