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.
I have shot many 7mm wby's for 35 years. They are faster than the 7mm rem mag but not 200 fps. Closer to 100. Freebore rifles are very accurate. I have several wby's that will shoot 1-2" groups at 400 yards. If you are building one I would do the 7mm stw. Wby brass now is just way to expensive. I think the 7mm wsm, 280 AI, 7mm jrs or 7mm gibbs are better choices near the 7mm rem mag velocity range if that is the class you are looking for. If you want a magnum the stw is the one.
