    Arrived pretty quick, packaged up pretty good, I haven't opened them to use any yet just stocking ammo.

  • Head hunter said:

    Shoots amazing accurate and plenty of knock down power for plucking down rodents such as ground hogs . You can reach out and touch something with accuracy and confidence .

  • Bru said:

    It's Hornady Black. Goes down range well, gives decent groups at 50 & 100 Yards through a Hellion. It's not Match grade but it is consistent for my usage. Good prices and quick shipping is always a bonus too! Thanks Ammo.com

    Not a lot of gas blow back. Nice and smooth out the barrel and suppressor. Over all highly impressed
