The others are right, as the "06" will not clean up. Of course you could go with the Ackley. You might also think about the 6.5x55AI or the 6.5x57AI. They'll clean up. The 6.5x57AI will do about 2950 fps with a 140 grain bullet. Cases are nothing but .257AI necked up to 6.5. There are a few guys using it for long range target shooting right now, and it works very well. The one advantage of these two rounds is when shooting very long bullets you have plenty of room in the mag well. Another beauty to look at is the .270WSM necked down to 6.5mm. Your looking at about 3150 fps in a short action with a 140 grain bullet. This one is easy, and there's almost no fire forming issues. Of course you could do the samething with the Remington 7mm SAUM. Neither one will show much case shrinkage on fire forming, and both look to be winners. Although the 6.5WSM is a little more common.
