  • 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!!

    This ammo is very consistent. Bench firing my Sako .223 I can put three consecutive rounds in a nickle at 100 yds. Love this ammo!

  • Al said:

    As good as Federal and a lot less expensive.......Federal is supposed to be the Cadilac of ammo.....well, PMC is equal if not as good or even better.....I am a user from now on.
