The 6.5 WBY RPM (Rebated Precision Magnum) is based on the lengthened version of the .284 Winchester. The large body diameter, low body taper, and 35-degree shoulder mean that case capacity is greatly increased, leading to higher velocities.
Bullet Diameter: .264 (6.5mm)
Common Reference: 6.5mm Caliber
Max Case Length: 2.57”
Production Start: 2019

The Weatherby team sits down with Mack Winzenburg and Jared Smethurst to talk about the 6.5 WBY RPM. Listen as the team discusses the reasons for the rebated rim, the 6.5 market, how the 6.5 RPM fits within the Weatherby line of ammunition, bullet ballistics and more!
The Long-Range X Bullet (LRX) line is designed after the best-selling Tipped Triple-Shock X Bullet, the LRX bullet design increases Ballistic Coefficient values by increasing ogive and boat tail lengths to improve the bullets’ long-range ballistic performance. An all copper bullet with polymer tip that initiates expansion, causing the nose cavity to open instantly on contact doubling the bullet’s original diameter while creating four razor sharp cutting petals that wreak extensive internal damage and produce massive wound channels.

Hammer Bullets™ are turned on a CNC lathe and use a unique solid copper blend that is designed for maximum terminal performance. Each bullet is weighed and micrometer measured as it is produced. The result is an incredibly consistent product with unparalleled quality control. The hollow point design, initiates expansion upon impact, shedding petals immediately, with the remainder of the bullet staying intact with a blunt front for optimal wound channel. All Hammer Custom Bullets are designed to optimize Weatherby’s flat shooting cartridges.
Take a deeper dive into Hammer Bullets with our On Our Mark podcast. We sit down with Bryan and Steve of Hammer Bullets to talk about the performance and what makes Hammer bullets different from similar projectiles.

The InterLock® features an exposed lead tip for controlled expansion and hard-hitting terminal performance. A secant ogive design — one of the most ballistically efficient profiles ever developed. The raised ring inside the jacket is embedded in the bullet, combined with the one-piece core, keeps the core and jacket locked together during expansion to retain mass and energy.

Robert Sweeden (verified owner) –
I purchased a back country in an 6.5 RPM and absolutely love it. My rifle shoots excellent groups and has taken two elk, two mule deer and a bear. The last elk was taken at almost 700 yards with one well placed shot. The cartridge seems to perform on a level with the larger calibers.
Excellent cartridge and excellent rifle.
Well done Weatherby.

I bought the 6.5 rpm last year in the hunter model , It’s exceptional accurate for a thin barreled hunting rifle (1/2moa/100yds) love the rifle and Weatherby’s outstanding calibers …
