A longer barrel equals more velocity, which makes shooting longer distances easier. Not that shorter barrels are not effective at long range, but more velocity leaves less room for errors. That being said, on a modern 308 with modern bullets and powders 20" is considered a 'safe' short barrel. 18" is short and people usually start quoting 800 yards effective range. 16.5" is primarily designed for suppressors. In Canada, where aural safety is a crime, the rifle will be obnoxious for extended shooting sessions. That's my opinion anyway. I wouldn't go shorter than 20" using a factory barrel. With a custom barrel and cut chamber I would stick with 18" for a light handy rifle.

I have the 20" pipe and so far that gun is giving book velocities for the powder charges listed. Shorter pipes may not always produce the lower velocities.
In any event that thing is going to bark. Shorter barrels DO seem to create more muzzle blast in my scholarly opinion...
