velocity vs barrel length

[Catfish]

Yes is not always the right answer. It depends on the burn rate of the powder and the amount of powder your burning. The easiest example is a .22 sub-sonic rimfire. They have such a small amount of powder that they are faster for pistol lenth barrels then for a 26 in. rifle barrel. This also can happen when useing small amounts of a fast burning powder in a centerfire rifle. The guys that are useing the 30 in. barrel to get more velosity are paying for it because they have to use very large amount of a slow burning powder to get any gain. So while yes is usually excepted as the answer it is not always true, by with most factory loads and barrel lenths it holds.
