Designed for Service Rifle competition in the M16A2/AR-15A2, our 22 Cal bullets have set an incredible number of new national records. The 77 grain #9377 Matching allows seating to an OAL that permits cartridges to be loaded into M16/AR15 magazines. 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.
