Home Forums Hunting & Shooting Ask The Gunwriters Weatherby .338 RPM

338 rpm 225 grain Barnes, weatherby factory load.

Weatherby Backcountry 2.0 with 20" barrel:

2600 fps.

Looks like the hype is a 200 fps difference from the chronograph.

To put this in perspective, at 15 below zero, I'm seeing 2650 fps from 338 rcm factory 225 grain interbond ammo, fired from the ruger carbine.

That’s significant but not unusual in my experience. What is disappointing is that not only is it 200fps slower but from a barrel 2” longer than their claim. Obviously hand loading can overcome some of the deficiencies but that’s not how it should work.
