Designed for Service Rifle competition in the M16A2/AR-15A2, our 22 Cal bullets have set an incredible number of new national records. With the introduction of the 80 grain #9390, the M16 family of rifles really became a force to be reckoned with in National Match competition. Because of its extreme length, the 80 grain Matching requires a twist rate not slower than 1 x 8 inches. However, it must be seated to an OAL that requires single loading in the M16/AR-15 series. While they are recognized around the world for record-setting accuracy, Matching and Tipped Matching bullets are not recommended for most hunting applications. Although Matching and Tipped Matching bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz or Varminter counterparts. This bullet requires a barrel twist rate of 1 x 8 inches or faster.
