  • Carl said:

    Will be ordering more I am very satisfied with the delivery and price ammo shoots good

  • AZ SHOTGUN said:

    Great ammo for the price.

  • Nate said:

    The ammo itself LOOKS beautiful compared to Lake City penetrators but I have not shot it yet so I can't comment on that. I paid more per round, but that is just the market, not Ammo.com.

  • Bigthiss said:

    Great ammunition for the price. I used to buy the federal loose bulk ammo in 500 and 1000 but there were always at least 10-20 that were either faulty loads or misfired. This ammo is hands down the best for the price that I have purchased and shot. Highly recommend!!
