  • Rhonda7764 said:

    The best value, fastest shipping and great ammo.

  • WWIIIHundred said:

    I normally don’t purchase steel or aluminum rounds, but it’s hard to say no when I literally can’t find or purchase any other types of ammo for my Windham Weaponry 300 BLK. I was worried that I would get a double feed or lots of jams. I honestly can say after shooting 100 rounds at the range at 100 yards; I didn’t get a single one with this ammo. My shot groups were decent too for what I consider sub par ammunition. I was honestly surprised at the results. I am definitely buying this ammo again. The best part is the ammo came to me instead of having to fight long lines hoping that there will still be ammo left on the shelf when it is my turn to grab some.

  • Savage300 said:

    I normally don't buy steel or aluminum case ammunition but due to availability at this time I decided to give it a try. I was pleased to not have a single issue during target practice. I didn't spend time worrying about grouping but all 200 rounds I used worked flawlessly. Will definitely order more.
