Big Redhead, I've used and loaded for the 6.5x06 a lot, actually shot the barrel out one. It had a 25" Douglas with a 9 twist. I never was able to get the kind of velocities I see listed here on the fire. With the 140gr bullets 2900 or so was tops and with the 120's 3050 or so was tops. I really like the round, it was very lucky for me. With it I killed my very best(so far) mule deer and before witness I killed a coyote at something over 500yds with it. But, when it came time to re-barrel the 6.5x06 became a 280AI. Never the less, the round is a great one. The 140gr bullets hold their velocity well way down range. It's worth a look.
