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 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.
