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.

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.
