Details

Our once fired brass, 300 Blackout cases are sorted by size, then washed and tumbled. Steel, aluminum, and Berdan cases are removed. The 300 AAC brass may include commercial, military, converted cases which may have minor dings, dents, slightly bent mouths, or other slight imperfections; but most flaws can be easily removed during resizing or will be shot out upon your first firing. If you are expecting a perfect case, then you would probably be happier with our new brass; these are quite good, but not perfect. These brass 300 Blackout cases are one of your least expensive options when doing bulk reloading.

For additional information on our Once Fired Brass, please see our "Brass Information" page.

Best 300 blackout brass I've had in awhile

Ordered from a number of places, and this was the best! The brass 300 blackout was good, but the service and shipping was outstanding! Happy to shop here and will be recommending to my buddies.

300 Blackout Brass OFB

Ordered these awhile ago, and they look great, a few have some minor dents, which are easily shot out. Great clean brass for the price. Lol, read that post about the converted cases. Must be a newbe as when we first started shooting these, converted was about the only things out there! Love to read these reviews and laugh at them!

And if you don't inspect ALL of your brass before you start reloading, you are a special kind of person. I've received new brass from Startline that had a number of cases in them that didn't have primer holes in them!

Some people talk the talk, but don't walk the walk. You can tell a new reloader by how much they bitch and moan about things. Grow up pumpkin!

converted cases

I didn’t expect 20% converted 223 cases, I order from another site that says up front that there maybe up to 20% converted cases but there never is. the description for these said mixed 300 blk headstamps so was disappointed with so many converted cases, other than that everything was as advertised. Oh there was one with a live primer, I deprimed it without any issues but still it shouldn’t have been there

A manager responded to this review

Hello there. Thank you for the feedback. You posted this review as a guest, so I can't reach out to you directly. However, please see our "Brass Information" page (https://www.usreloadingsupply.com/brass-information). On that page, you'll see that we don't sort by headstamp unless specifically stated, which means some amount may be converted, anywhere from 0%-100%. Converted brass is usable. If you find unusable cases, please let us know.

Regarding the primer, even if it was unfired, it was washed in water and a few chemicals/detergents for at least an hour. So, although that's not a guarantee, there is a good chance that it was no longer live. Again, unfired primers are touched on in our "Brass Information" page.

Super!

Just received my second order form US Reloading, and I am impressed with the fast shipping, very high quality of the brass, and super customer service.

Second order

This is my second order of once fired brass and this time tried the 300 blackout. This is just as good as the 308 I received except not decapped. Called and asked, found out they typically decap the larger rifle brass which could be Berdan primed. Makes sense. Thanks.

Mixed head stamp 300 blk brass.

Mixed head stamp 300 blk brass mostly LC, REM, ran all through resizing die for the heck of it, clean, a few still had primers. One casing had been chewed up by the ejector, 102 total so... not bad for the price! Especially in today's environment.

Good brass at a reasonable price. I appreciate it being cleaned before I got it. Tired of ordering and receiving dirty brass from others. Have to clean them before I can inspect them. This brass was easy to inspect. Thank you.

Better than advertised.

Excellent all around. Ordered on 10/19 and received on 10/24. During the initial inspection, I could not find a single unserviceable piece of brass. The count total was 110. Very happy buyer.

Great brass

Brass looks great, and no bad ones. Good prices too, just wish there were more in stock.

Great quality. The best option right now

This brass is very clean and good quality. Most are brass with a few nickel plated mixed in. I had a new rifle built and the only way to get ammo right now is to build your own.

I was pleased how quickly they arrived in the mail too.
