[QUOTE="keithcandler, post: 84397, member: 3728"] [b]Re: .257 Weatherby[/b] You can figure +250 fps more out of a 257 Weatherby with no freebore. I hand load my ammo and would never even consider shooting a factory round. In a chamber with no freebore, you can not shoot factory round, bullets have to be seated for that chamber. Accuracy is in the high 2's and low 3's for three shot groups using 100g nosler partitions. Sierra 100g spt bt are a little bit better with velocity at 3750-3850 depending on the bbl. I do believe that 3 groove bbls are faster than 6 groove bbls, at least on the bbls that I have had. [/QUOTE]
