What is the lowest velocity for 6mm 95 gr VLD from 10" twist?

I will say this one last time and then you are on your own.

You NEED a 9 twist minimum to shoot the 95 grain Berger VLD. An 8 twist is better still, but a 10 is a waste of time. You want an SG of 1.4, you will not get that with a 10 twist. Berger states on their site that you need a minimum of a 9 twist.
Why when you are buying a new barrel are you intentionally shorting yourself?

I tried the 95gr VLD from a MUCH faster round, and even at much greater speed which in turn means a higher SG, it was not stable. I even tried slowing it down, still no luck. Lighter bullets, such as a 70gr Berger, shoot awesome. But anything over an inch long does not shoot for beans compared to shorter bullets.

Just because a bullet is decent at 100 yards means nothing. Your groups will suck the farther out you go due to poor stability. I know as I have tried exactly what you are thinking of.

I also doubt you will get 3300fps with a 95gr VLD from a .243. That is what my 6-284 will do, and my barrel is only 4 inches shorter. You will be closer to 3100.
 
I was shooting the 95 VLD out of a factory Savage varmint
(9.25 twist un-measured) 243 at 3200fps with a 26" barrel and it didn't work, for me anyway. It was a different story from day to day. One day it would shoot good, the next day it might open up to 3" at 100 yards with the same load. I don't know what the cause was for sure be it twist rate, load combo, temperature change, bedding, scope, or me but it Did not work. I never got any to keyhole out to 600 yards but it was anything but consistent. 8 twist 6br shoots them great FWIW
