[QUOTE="J E Custom, post: 394619, member: 2736"] The barrel should be a 1 in 10 twist and will handel the 300 grain bullets well because of the velocity. The 300 grain bullets can be loaded to 2750 to 2800 ft/sec. The 250grain factory loads are 3060 ft/sec and 5200 ft/lbs energy. The 225s can be pushed to over 3300 ft/sec. As far as accurate, the big Weatherby can be extremely accurate if loaded correctly(Neck sized only) and with a head space of .0005 or less. I have a 30/378 that has shot a .092 5 shot group @ 100 yards. The powder I like is US 869 and H 50BMG with Fed 215 primers. J E CUSTOM [/QUOTE]
