ORIGINAL: eldeguello

As a rule of thumb, we say that a standard round such as the .308 would lose about 25 feet per second for each inch cut off a barrel like yours.
Would the loss of velocity be noticeably different for cartridges that work best with slower burning powders? for instance the 300 mags or 25-06 rem?
