    So far I probably used 100 150 rounds. No problems with the ammo at all.

  • anthgrge said:

    Full metal jacket "brass shells" neatly packed easy to carry in convenient carry canisters. Great shot at the range.

  • Karl said:

    For the price I'd say a good purchase. Out of 200 rounds maybe around 15-20 rounds that I'd assume had bad primers and didn't fire.

  • BWalter82 said:

    This ammo is clean firing, accurate to 2 moa, and I never had a problem in any of my rifles; probably the "best bang" for the buck out there!

    I got 1000 rounds of this. Just shot it today and it consistently chronos 100fps slower than advertised. NOT HAPPY AT ALL. Order another brand if you want full power ammo.

  • Tarpon said:

    As expected

  • NuSparkey said:

    Nothing like using good ammo to make you feel good about yourself. Pushed it out to 300 meters and anything off target was probably my jittery finger. Cycled well under rapid fire. I like it!

  • Rick said:

    No FTF or FTE's in my Ruger Mini-14

  • Jack said:

    Great ammo and a very reasonable price. Great service.

  • skywarrior said:

    Great fun ammo for steel targets.
