I have the Remington Magnum which has about the same case capacity as the Weatherby but lacks the freebore so it suffers lower velocity. I have thought about getting the throat reamed out. Anyway, 7 mags are great for longer range, well what I consider long range, out to about 400-500 yards. To me the Weatherby is the ultimate 7mm. It's a hell of a lot easier on barrels than the STW or ULTRAMAG, and also easier on my shoulder and ears.
