If the length of the barrel was that important, you could have just added some washers between the barrel and the action!
I'm interested in a 6.5 just haven't figured out which one. How much more velocity do you think you'll get with those two inches? You have a very nice rifle for sale at a very reasonable price.
honestly, less than 100fps, probably more like 60 fps, i just like a 26" barrel, I have a 6.5 X 284 on order, between the 6.5 creed and Norma I can cover all but the big bears
