Bertram Brass 43 Beaumont Formed Unprimed Box of 20

This is good brass and although pricey, is as close as you can get to the real deal. There were two minor issues with quality control: 1 - inconsistent head stamp depth. This varied from adequate to too heavy. The heavily stamped pieces measured against a flat surface (like your bolt face!) have a slightly thicker rim. This was remedied by light polish over flat surface with 600 grit paper before priming. Following the polish, primer pockets were checked for correct depth. 2 - inconsistent extractor groove cut. 1 out of 3 pieces would not fit in the shell holder. Depth of groove varied by 20 thou or more. Since the shell holder is used for other calibers, the brass was modified so all extractor grooves are the same depth. For someone looking for a load and go casing, this would not be the product for you. If you're handy with making slight modifications to cartridge brass, this is a great addition to your Dutch Beaumont shooting experience.
