[QUOTE="boomtube, post: 545673, member: 9215"] "In reality faster powders tend to work better in short barrels and slower powder tend to gain more velocity in long barrels, " Not really but that's a common misconception. First, peak chamber pressure occurs in less than 4" of bullet travel so that part doesn't matter no matter what powder is used. Second, any powder that will produce the max speed in a long barrel will do the same if you cut the same barrel back. (Not the same speed of course but it will still be the fastest powder.) Meaning it's the time:pressure curve that matters for what will be fastest, not the burn rate:barrel length that will determine the most efficent powder for any given load in a given rifle. [/QUOTE]
