Trying to find out how much is lost from the 20" to the 16" to the 13".
That being said, why do most 308 sniper rifles have 24 inch barrels? If a sniper could get the same effect out of a shorter barrel I think they would use it because it would be lighter, Right?Barrel length doesn't determine accuracy...
Light is good up to the point it decreases your ability to hold it steady (target rifles tend to be heavy, plus there's the issue of variation from the first shot in a cold barrel to subsequent shots, favoring thick and therefore heavy barrels), but often a sniper is trying to "reach out and touch someone" at long range, and the extra muzzle velocity helps. A bit more reach, less wind drift, etc. If he's trying to make a marginal shot it could make the difference.devildoc said:That being said, why do most 308 sniper rifles have 24 inch barrels?
