PETERSON CARTRIDGE 7MM STW LONG BRASS

The Peterson Cartridge 7mm STW Long Brass is engineered for reloaders who demand maximum precision, durability, and case uniformity. Designed in Peterson’s “Long” configuration, this brass provides additional length for shooters who prefer to trim cases to exact specifications, ensuring a perfect chamber fit and enhanced accuracy potential. Manufactured in the USA under strict match‑grade standards, each case is meticulously formed, heat‑treated, and inspected for consistency. With exceptional strength, uniform internal volume, and reliable ignition characteristics, Peterson’s 7mm STW Long Brass delivers the performance needed for long‑range hunting and precision shooting applications.

The Longs solve the problem of excessive headspace in belted magnums by moving the shoulder forward .010”. This prevents the brass from over-stretching on the initial firing, thus increasing longevity in the casing
