Lightning fast delivery, securely packaged, excellent communication.

Winchester ammo has always worked very well for me to eliminate groundhogs on my farm. It has always performed flawlessly and accurately.

Great Shells of Dystany

Winchester products are reliable and determined.
Finally found at a reasonable price.
And certainly came in a timely matter as other items these days.
Brass is best, I'm not a big fan of steel jacketed.
Really tough to find right now in the Midwest.
Thanks GunPrime / 2 Birds Outdoors !

Don't ever get old,
Don't ever slow down,
And pick it up a notch !

I have been looking for months for 5.56 ammo. Not only do they have it, but at a discount for a name brand. I also received my ammo in about a week. Great company and prices!

Awesome company!!

I like how fast I got my delivery and get notifications when they are back in stock! The ammo is great no problems at all!

By Mitch Thompson on 05/11/21
First box of 5.56 ever, so don't have anything (other than rounds shot in the military 18+ years ago).

Shot 50 rounds to zero in my AR-15. No misfires or squibs, so that's good. I'd buy them again.
