This 5.56x45 cartridge by Magtech is perfect for match shooting, but you’ll no doubt enjoy firing it casually to see just how accurate your custom AR-15 can be. Its bullet is the reason for this -- Sierra’s MatchKing is a real tack driver of a projectile, just shy of being classifiable as a surgical instrument. This bullet’s thin jacket is remarkably concentric, and its weight is standardized within ± 0.3 grains. The bullet’s hollow point meplat does not affect its terminal performance -- rather, that narrow hollow point immunizes it greatly against wind deflection. This MatchKing’s boat tail design amplifies its ballistic coefficient to flatten its trajectory, and its cannelure prevents it from setting back during feeding.
A Magtech cartridge evinces all the quality so large a manufacturer is able to deliver. Its first rate casing is made of brass, and thus reloadable several times. Its propellant burns clean to maintain your rifle’s action, and its primer needs to touch your firing pin ever so slightly in order to create reliable ignition.
