Frank, the owner of SnipersHide reaches out to 1000 yards with the 18" barrel.

Personally, I have two .308s chopped to 20".

I agree with 18" being the shortest effective 308 for muzzle velocity potential. But there is a difference between reaching out to 1000 and taking out at 1000. I know that our M24's were maxed out for soft tissue at 1000 meters. They were 20". We did tests with gear and heavy clothing and actually only had 1 in 5 penetrate.
