The 7mm Winchester Short Magnum (WSM) and 7mm Remington Short Action Ultra Magnum (SAUM) were once poised to be the next great advancements in short-action magnums. Designed to push long-range ballistics from compact rifle platforms, they offered magnum-level performance with efficient powder use and reduced recoil. But the market didn’t follow through. Ammunition dried up. Bullet manufacturers moved on. And yet — the rifles remain, the cases exist, and the demand is resurging.

At Gold Country Ammo, we don’t just acknowledge forgotten cartridges — we build bullets for them. Custom-designed, twist-rate optimized, and ready for reloaders looking to breathe life back into their 7mm WSM or SAUM rifles.

📘 Cartridge Compatibility

  • Primary: 7mm WSM, 7mm SAUM
  • Extended: 7mm Rem Mag, .280 AI, 7mm PRC (for shared bullet profiles)

These bullets are designed not just to feed, but to perform — offering high BC profiles, controlled expansion, and stable flight at all practical hunting distances.

🔍 Why the Industry Dropped the Ball

Major bullet makers cut support once factory ammo slowed. Load manuals stopped expanding data. The result? A blackout of support for rifles still capable of sub-MOA groups and magnum-tier terminal energy.

GCA is changing that.

We hand-swage .284 bullets in grain weights tailored for these exact cartridges — with profiles designed for the velocities and twists they were born to shoot. Whether you’re chasing a 160gr soft tip load for a deer rifle or a 175gr Razorback for elk at 600 yards, we’ll build the bullet for your rifle, not a corporate SKU list.
