The Berger calculator seems to say a 140gr 6.5 @ 2950fps needs an 8 twist barrel. What are you guys running on your 6.5s??

My 1 in 9 6.5-06 stabilizes the 140 VLDH just fine.
Good luck and shoot straight

Not running it yet, but I got an 8 twist for my 6.5 SS. Planning to run 143 gr ELD-X when I get it all together.

I have a .264 WM and a 6.5x55 that each have a 9 twist barrel. Both rifles shoot 140 VLD's well under 1/2 MOA.
I have a 6.5-284 with an 8 twist Krieger. It is not much faster than the 6.5x55. With 140 AMAX's, there is very little difference in trajectory out to 600 yards. But, there is a significant difference in wind drift, in favor of the 6.5-284. I believe that to be a reflection of improved stability (and, therefore, bc) from the 8 twist.
I noted with interest a recent post by elkaholic indicating he had heard through the grapevine that Berger will be releasing a 155 EOL hybrid in 6.5 in the near future. Based on some rough estimates of bullet dimensions that I plugged into the Berger calculator, folks with 8 twist barrels should be able to get good use from the new bullet. Something to think about...
