Has anyone here done any scientific "testing" on the 6.8spc to see what kind of velocity is lost when going from a 16" barrel down to a 12" or even a 10.5"? I realize this is dependent upon ammo but I was looking more for a "ball park" number. I like the idea of a 12" but I am not wanting to give up to much velocity and or even accuracy.

If 16" inches will work I would head in that manner. Better ballistic and usually better accuracy. Too short lost powder.

Re: 6.8spc velocity vs barrel length
I've heard the shortest barrel to where the 6.8 would work well was 12" but 16-20" would be ideal. The 6.8 doesn't gain much from barrels longer than that.

The round was designed around the 16" barrel. I am running a 20" which gives more fps, but not a lot more.

Re: 6.8spc velocity vs barrel length
Check out the 68Forums. A few guys with the right barrels are getting around 2800-2900FPS from a 12.5" using 85-90gr loads. That number will go down as the bullet weight goes up but the 6.8 does perform well as a SBR.
I'd use no less than 11.3" which would be a Wilson Combat pipe. However, if the choice was given, a 12.5" ARP from H.
I can't wait to see what numbers LWRC is getting from their Six8....
