On the Barns site they had some recommended loads for 240 Weatherby Magnum. Well I used those for my 6x284. 59grs of Re#22 pushed those things into less then 1/2MOA at 100 yards. Awesome but their BC is quite low. Barns says estimate my load at about 4,000 FPS. That's gotta be good enought for a 300 yard Coyote shot.
