Pete,
tell us now about that 8 twist 257 Bee! I plan on doing the same thing
used a Weatherby Mark 5 action ,fiber stock , put a contour # 4 ,28 inch Brux barrel 8 twist , glass bedded and floated this rifle , Nightforce picatinny base and rings , 5.5 -22 x56 Nightforce scope . this rifle and my other 257 Weatherby mag. rifles like 103 gr. Hammer Hunter bullets ,Reloader 25 powder , my velocity with this rifle was an average 3680 FPS. 3 shot groups were 3/4 inch at 100 yards , but my Ruger #1 257 Weatherby mag. with a Brux barrel 27 inch ,10 twist shoots 1/2 inch 3 shot groups at 100 yards with the same loaded cartridges . but i would still do a 8 twist for a Weatherby mag. i purchased a brand new 257 Weatherby mag. reamer used for all my 257 Weatherby mags. and from now on for all of my rifles i will never ever rent a reamer on any cartridge ever again there is a difference. i used the Berger reloading book for my recipe 1 gr. below max.
