    Difficult Caliber, Good Brass

    Posted by Alex on Dec 1st 2025

    300 BLK takes a little time, but the brass is good. One or two were damaged, nothing to worry about. All of the brass are well packaged and reload well. They prime well and reload well, if an experienced loader. The brass looks new, clean and polished; well packaged and random once fired. Frustrating caliber to load but one step at a time while learning, a very good brass source and prices. Trimming, debur, and chamfering takes patience and time to get good results.

    Brass Range

    Posted by Alex Nguyen on Nov 13th 2025

    I have made several spent-reused brass from Brass Range and have always been very pleased with the quality and selection. None of them are stepped on or damaged; although one or two cannot be reloaded due to the primer pocket. I use the Lee Auto Bench Prime which is as good as it gets. So out of 100, 99% may have a problem but you throw them in the "dummy" round bin. A dummy round is good for LOA and fit. I would order again and am very skilled to discard any mismatch. A few had slight damage but they reloaded fine. For the money, the cleaned and polished brass is a big gap from range brass you pick up or collect. So my personal experience has been a 4.8 to a 5.0 insofar as once fired brass. I was not disappointed and the price was very reasonable.
