Brass cases Peterson .300 Win Mag

"I am thrilled to announce that as of July 20th, 2020, Peterson Cartridge has officially added .300 Winchester Magnum brass to our product lineup," declared President Derek Peterson. "The journey to produce this belted magnum case has been arduous, frustrating, and costly. It has taken us over three years to bring this cartridge to market, with well over $50,000 invested solely in experimental tooling."

Peterson elaborated, "Crafting a brass casing with a high-quality belt is a formidable challenge. Achieving the perfect tooling requires an iterative process, and our endeavors with the .300 Win Mags involved more iterations than I care to count."

"When introducing a new caliber casing for the first time, we initiate the design and ordering of all necessary tooling," Peterson explained. "Following its arrival, we conduct what we call a proof-of-concept (P-O-C) run. Typically, with most of the 30+ new tool packs we've developed, we achieve our 'Best Vision' casing after one or two iterations."

"However, the .300 Win Mags presented unique obstacles," Peterson continued. "Many of our initial P-O-C runs resulted in belts that weren't sufficiently crisp. Consequently, we would redesign and order different tooling, only to encounter new challenges. While some runs produced a satisfactory belt, it wasn't precisely positioned. In other instances, although the belt was correct, operational efficiency or scrap rates proved problematic. Achieving the optimal grain structure in the casing walls required several tooling iterations. After encountering setbacks, we even speculated that the issue might lie with the dimensions of the brass cups used as raw material, prompting us to redesign and retry."

"After three years filled with moments of uncertainty and countless iterations, we finally achieved success. We can now produce belted magnum casings, and our .300 Win Mag casings boast belts of exceptional quality, rivaling any in the industry. Our ballistician has rigorously tested these casings, firing some 20 times in succession at SAAMI max pressure with minimal shoulder resizing, and they have proven to be incredibly durable."

In conclusion, Peterson expressed, "To our loyal customers who have eagerly awaited the release of .300 Win Mag, we extend our gratitude for your patience. Finally, your wait is over; we've achieved the perfect belt!"
