[QUOTE="azsugarbear, post: 340147, member: 4809"] I have a 6.5-06 AI that Kirby built for me a couple of years back. You can reach 3,200 fps with a 140 gr. bullet, but you are at the upper end of that caliber's capability. You are hoping that you will be lucky enough to have a good grouping or "node" at the upper end of that spectrum - which is seldom the case. Additionally, there may be other idiosyncracies with the barrel or rifle that will be beyond your control. For example, my custom rifle wears a Lilja barrel with1 in 8 twist for the 140 grainers. While it has a .264 bore, it is a "tight" .264 bore. It just came that way from the factory. It simply does not do well with the thin-jacketed Berger VLD. It does group better with the 142 gr. SMK's or the 140 gr. A-Max's. But it really shines with the 130 gr. bullets - like the Accubond. My rifle was built and set-up for the 140's, but the barrel (call it harmonics, gremlins, whatever) simply likes 130 grain bullets better. What I give up in BC, I more than make up in accuracy. If the higher BC and increased velocity is paramount for your shooting, then give a little on barrel life and go with a "magnum" 6.5 - meaning case capacity and not just a magnum moniker. [/QUOTE]
