[QUOTE="M9Powell, post: 1233723, member: 97934"] 7 mm Weatherby is interesting. Are you running the usual Weatherby freebore? What twist? In my 9th edition Hornady manual the Weatherby outruns the Dakota & the STW with the heaviest bullets listed (175s). And equals the Ultimag with a lot less powder. 7 mm Weatheby 26" barrel 3100 fps 70.1 grs of H4831, 71.8 grs RL-22, 76.1 grs H1000. 7 Dakota 25" 3000 fps 73.5 grs RL-22, 77.6 grs RL-25 7 STW 26" 3000 fps 68.6 grs RL-19, 79.9 grs VIHT 24N41 7 RUM 26" 3100 fps 88.6 grs RL-25 all the other powders topped out @ 3000 fps so 1 could make the argument that the Weatherby beats it with 18 grs less powder.
