338 WBY RPM

(1 customer review)

$79.00 – $109.00

The 338 WBY RPM (Rebated Precision Magnum) is based on the Weatherby 6.5 RPM necked up to accept a 338 caliber bullet.  The 338 RPM was designed to take advantage of Weatherby 6-Lug action to get magnum performance in a 5lb rifle. The large body diameter, low body taper, and 35-degree shoulder mean that case capacity is greatly increased, leading to higher velocities.

Upon the launch of the 6.5 WBY RPM in 2019, we began to dream of what could be next in the RPM family. Having successfully launched a 5 lb rifle in a 6.5 caliber magnum cartridge, I began to imagine what it would be like if we had a big bore option that could fit in the same Weatherby Mark V 6 lug action. Field testing for the 338 WBY RPM began back in 2020 when my son was able to take the first animal with Weatherby’s 16th cartridge introduction on a spring bear hunt. That following fall, Brenda and I both shot elk and moose ranging from 90 yards out to 550 yards and the cartridge performed tremendously. I am truly honored to be able to carry on my grandfather’s legacy of cartridge development and rifle building. The pairing of this new cartridge with our latest rifles reminds me of one of his old slogans that said “Tomorrow’s Rifles Today.” I only wish he could be here to see the innovation and development that our amazing Sheridan-based team is able to accomplish

  1. Justin Berry (verified owner) –

    I own the backcountry 2.0 with the 18” steel barrel. I love this rifle, it is now my go to rifle.
    The 338 is super efficient and with the break and amazing stock it has the recoil of a 30-06.
    My rifle loves the 185gr Barnes ttsx
