    Excellent price for the ammo, everything arrived quickly and packaged well. Ammo performed great at the range, making it yet another great day at the range!

  • 223/556 said:

    Price was low, came in good packaging, ammo performed as it should cycling and firing, and the order arrived on time I am very impressed with this product

  • Alex said:

    Those rounds go off every time tearing through things

  • Ranger5688 said:

    Bullet strength and bullet placement are key factors,. I wouldn’t recommend all 223 for big buck deer,. Only a few will do the trick ,. It takes a powerful vital hit to bring a buck down,. The penetration and shock wave is what’s needed to take the game down ,. Choose your caliber wisely ,.

  • Bob said:

    Ammo fired without any jams, misfires or problems of any type. Ammo feed was smooth and no ejection problems. All spent casings cleared weapon cleanly.

  • Dave said:

    Great ammo for coyotes Local stores don't carry 40 grain anymore I will buy from your company for other ammo when my stocks get low
