Designed for Service Rifle competition in the M16A2/AR-15A2 our 22 caliber bullets have set an incredible number of new national records.

Having heavier jackets they will not provide the explosive expansion of the lightly jacketed Hornet or Blitz bullets at equivalent velocities in small varmints. If used for varmint shooting ranges should be kept short to ensure precise shot placement. - Dia.
