.300 blackout ammo by KLS, Verified Owner, November 15, 2023
It's a darn shame you have to order ammo online. This cycles fine through a modern sporting rifle (AR-15) and will thump deer size game

Hornady .300 BO by Richard, Verified Owner, December 6, 2025
I've been using this ammo for a while now and they have done a great job on the hogs. Most of my shots are at about 50 to 70 yards and they have good knock down power for that range. I'd recommend them.
