“To make a new caliber casing for the first time, we design and order all the tooling. After it arrives, we do what we call a proof-of-concept (p-o-c) run. With most of the 30+ new tool packs we’ve designed, we end up with a “Best Vision” casing after one or two iterations.
“But these .300 Win Mags! With many of the p-o-c runs, the resultant belt wasn’t crisp enough. So we would redesign and order different tooling and try again. With some runs we’d get a good belt, but it wasn’t in the exact correct location. Some runs, the belt was good and in the correct location, but the equipment wouldn’t run it efficiently or the scrap rate was too high. It took a few different tooling iterations to get the grain structure in the casing walls just right. After some of the failed iterations we would speculate, maybe the problem is with the dimensions of the brass cups we are using as raw material. So, we’d redesign those, and try again.
“But after three years of unsettling self-doubt, and countless iterations WE GOT THE BELT. We can now make belted magnum casings! And we have really good .300 Win Mag casings on the shelf, with as good a belt as any in the industry. Our ballistician has shot some of these 20 times in a row, at SAAMI max pressure, with a minimum shoulder resize and they are still holding up well.”
Peterson concluded, “If you are one of the many customers who’ve called us every week to say, “When are you people ever going to release .300 Win Mag,” we have two responses. First, thank you for waiting. Second, FINALLY, here you go; we got the belt!”
