    Ran flawlessly & was cleaner than the Magtech and S&B 200gr range ammo that I had previously used. Will be buying plenty more. Thanks

    Awesome performance and accuracy even from a 7.5 inch barrel. I was really skeptical with the rounds being so cheap but after 200 rounds of reliable performance I'm sold.

    These 200gr subs are some of the best .300 Blackout ammo I've found to date. They're extremely quiet when suppressed, soft shooting and very, very clean. Couldn't ask for better. These are my number one choice for the range.
