What is the most popular 6.5mm cartridege? I am going to put a new Pac-Nor 8T5L barrel on my Weatherby Mark V and sell it unfired. The barrel matches the Weatherby contour. What barrel length is most popular? I ordered the barrel to be 26" so it can be at least that long, but shorter if that is the consensus.

Any opinions are appreciated.

edited to correct for wording!
