DO YOU SEE A DIFFERENCE IN PERFORMANCE FROM LET SAY .3 GR OF POWDER? You bet you do so why wouldn't you see a break-off in accuracy at a certain length/velocity. Harmonics is an important role in barrel performance and accuracy. The start of this thread was Barrel length. And yes according to that thread there was a difference in accuracy in just 1/8 of an inch.

I would really look at something like this very skeptically. So,this means a 23 inch barrel will show a significant decrease in velocity and accuracy over a 22 7/8 barrel? 1/8 of an inch?
The thing you can bet on with barrels is that the better quality barrels will give better performance than the low end barrels. When I say 'bet', it is what I mean. Probably 80 or 90 percent of the time a high end barrel will show better performance than a low end barrel. If you spend the money on a high end Lilja or Krieger for example, you are almost assured seeing better performance than a Shaw or 'AR Stoner'.
Another thing about barrels is that this improvement in performance is seen at longer distances most of the time. Guys here can easily get sub minute with a Shaw at 100 yards but that Shaw won't dependably hold that performance level at 300 like a high end barrel will.
As for barrel length, get the length that suits the primary purpose of the rifle or carbine. Guys want carbine agility with 1000 yard ability will never get an ideal tool for either purpose.
