Ordered a few hundred of these last week and they just came in. Looks real good! Shipping was fast and all the brass pieces are real clean and usable. Will be back for more soon.

Best 300 blackout brass
5
I've ordered from a lot of companies, but US Reloading is the best. Got my cases in no time flat and they were clean and in great shape.  Called and spoke with them about classes too, didn't know they had reloading classes in their store. Good people to talk to, very knowledgeable.

Put my order in for some AAC .300 blackout brass early one morning and was notified that it shipped later in the day. Sure was surprised to see it show up just a couple days later. Full count of 102 and all looked pretty good.

Best brass
5
Best once fired .300 blackout brass I've bought. Great shape, a few bent necks, but that is always expected. Very clean, ordered 100 received 102, so count was good. This was part of a bigger order and I was a little antsy on the box. When I got it, couldn't believer how much tape was on that thing! Almost every inch was covered, so I was pretty impressed, way to go guys! Thanks, will be back, Larry

Third order 300 blackout
5
Just got my third order of 300 blackout brass, and it still looks really good. A few bent mouths that the resizer will fix, but none that had to be tossed. Words well with those berrys bullets in my rockchucker. Keep it up guys appreciate it!

300 Blackout
5
I've used a number of companies that say they have 'once fired brass' and advertise that is one show once due to being from a military or law range. However, I find that these cases HAVE been fired more than that and are in poor quality.  Now I'm happy to find someone that actually tells it like it is and just says it has been USED and don't know how many times it has been shot. I ordered this brass, 300 Blackout from US Reloading and am quite happy with them. Got here on time, looks good too. There are a couple of dings on them, but after loading and shooting, they look just fine. Referring my friends was the least I could do after finding a great supplier.

300 Blackout Brass, great cases
5
I've ordered online from several companies, most over charge and the cases are still pretty dirty, even though I pay extra for 'cleaned and polished' cases. Tried USRS and was very happy! I got cases that were CLEAN AND POLISHED without having to pay more for it. Cases were in pretty good shape and all were useable. Mixed headstamp, but that is what the page said. WILL BE BACK!

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.

Mixed head stamp 300 blk brass.
5
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.

Great quality. The best option right now
5
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.

Second order
5
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.

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.
