7mm Rem. Mag. vs. 7mm Weatherby

[Jumpalot]

What are the real world differences between the two? I'd like info shooting 160 Accubonds and 168 and 180 Bergers. I thought they were pretty close in performance but I think I read that the Weatherby has about 5 grains more capacity.

According to the numbers in hornady's book the weatherby does have more powder capacity, and about 200 fps. but I am not sure what real world numbers are for the weatherby Vs. the remington.

Per Federal's specs on their factory ammo, 200 FPS in favor of the Weatherby, 400 ft-lb in favor of the Weatherby, using the same bullet:

Wow!! 200 fps??? That put's the Weatherby in the 7mm STW class doesn't it?? I didn't think there was that much difference.

I doubt that there is for the reloader. I'll wait until some reloaders sound in before I conclude the Weathery gets 200fps over the Rem Mag.

It seems that factory reloading specs are 50,000 psi for the 7 RM but 63,000 for the 7 Weatherby,WSM and SAUM. I have been reloading my 7 RM to the higher pressures and velocities for years with no problems and great brass life.

So, that mist I see is your 200 fps advantage evaporating.

Part of the supposed Weatherby advantage could also be the freebore built into many Weatherbys. The only purpose of extra freebore from what I can tell is to allow more powder and velocity. But it is frequently pointed too as a potential accuracy problem.
