    Ammo looks GTG

    Posted by Jagerhall on 24th Jun 2024

    This is a very decent looking finished product and the price is spot on. I have yet to push any of these rounds downrange. I will update if needed on ant FTF (feed or fire.) Shipping was fast and trackable. Although, when received, the air bladders were broken and 2 of the 3 boxes had completely spilled the contents inside the shipping carton. Not a big deal just took a minute to repack the rounds. Will/would use again.

    300 Blackout Ammo 600 count

    Posted by Tim W. Black on 10th Jun 2024

    Ammo works great. The delivery took longer than expected (eight days), especially since I live one state away. I ordered some different ammo from PSA at the same time and it arrived in two days. Response: Hello Tim! Good to hear that the ammo works great, but unfortunately we are currently back logged a few days and our current shipping lead times can be out to 10 business days. We are working hard to bring that shipping wait down to 1-3 business days. Thank you!

    .300 Blackout 220 gr

    Posted by Bill on 15th May 2024

    What can I say? I'm impressed ! This is really good ammo at a great price. Runs clean with no problems in my 9 inch SBR. Flat rate shipping ( other retailers could do this, but won't) Customer service is great! Real people answer the phone - who would've thought it ? I will be a return customer .

    600 rounds 300 subs

    Posted by BK on 10th May 2024

    Still waiting on the can so I've only run one mag just to try them out. They all went bang. Good clean brass. Only minor issue was the packaging for shipping. About half the boxes of ammo busted open so most of the rounds were loose in shipping box, but they were all there so not a big deal. Shipping didn't take too long, shipped after 3 business days.

    Really like their 300 blackout. No malfunctions and they pack 30 to a box. Like a magazine actually holds!
