223 REM 55 gr.

Ordered it on a Sunday, shipped on Monday. Great customer service. This ammunition I use often. With the correct shot placement, this ammunition does exactly what it’s manufactured to do. I use these rounds for a coyote and varmint hunting. Will buy often.

Best in the business

As everything that defiant does. it is amazing quality and great customer service. Only brand ammo i keep in my guns for go time.

ammo you can trust

This is the ammo I trust in a rifle to defend my family and make the shots that must be made if needed that we all pray never comes. You owe it to your family to have a excellent defensive round you can trust in you rifle and handguns. For me this is defiant ammo. I have it in all my carry and home defense weapons except the shotguns because they don't offer 12ga 00 buck yet.
