Most Recent Reviews Super brass by Michael S Miller, Verified Owner, August 6, 2025
Well made cost a little more than some but worth it for me.
Most Recent Reviews Long awaited Lapua for 300 WSM by stewarmy83, Verified Owner, February 1, 2025
Finally Lapua for 300 wsm. More consistent than the ADG brass I was using, and much harder than Norma or Nosler. We will see how long it holds up, but I anticipate quite a long time.

Over the last 20 years the firearms industry has seen a rise in the popularity of rifle cartridges designed to equal or exceed the performance of the traditional belted magnums but without some of the limitations of cartridge overall length. Among the multitude of new cartridges, one of the most successful of these has been the 300 Winchester Short Magnum (WSM). The 300 WSM provides many competitive features and advantages over legacy belted magnum cartridges, delivering energy equal to the 300 Win Mag and conveniently integrated into a short action rifle design.
