Weatherby®

SAAMI specification Weatherby chambers have a fair amount of freebore, this is the factory standard. If you intend to fire factory ammunition, use the standard chamber reamers.

If you want a shorter than standard throat, the gun should be marked as such and Weatherby factory ammo should never be fired in that gun as pressure problems will result.
