  • Big T. said:

    This is my second purchase of this ammo. The first purchase was 60 rounds. I had a great time zeroing and shoot the rifle suppressed. This ammo out performed my expectations. This purchase was 200 rounds for $342.00 including shipping. So $1.60 delivered to the front door was worth it to me. Happy shooting.

  • RazorUSMC said:

    Bought this ammo for a Run N Gun competition, it worked falsely as it should. I reload my own but with the short notice of this shoot I did not have the time to reload my own. I have some to trust Hornady products as I use there Lock N Load AP Ammo plant press. This ammo was great and was super quiet with my 10.5" SBR I will be getting some more soon so I have the brass to save this time.
