I have both a 6.5 x284 and a 6.5x06 AI. Just my 2 cents the 6.5x06 AI is a much better hunting rifle do to case design.It also burns about same amount of powder.
I have had two rifles bulit by Hillcountry rifles they both shoot sub moa to 600 yards that is farthest i have shot them.sometimes the rifle you have just needs a little help.Talk to Matt Hillcountry.
I have been a longtime looker never posted on this site living and hunting cailfornia barnes bullets have become a challenge for all of us we have no choice. I have found the ttsx expand a little better then the tsx also the faster you drive them the better considering accuracy.I shot them in 7 wsm at 3400 fps. on 130lbs deer with no problems.
