But really if your shooting past that you should have the optics to do so. Meaning at the very least a BDC reticle. The best method is turrets that are absolutely repeatable and its nice to have a moa or BDC reticle for those rushed shots! BDC reticle alone can be very effective with practice, but you cant argue that dialing in your turrets is the most accurate way to make a shot.... that being said if you're going to take the time to adjust your turn for a shot then there really is no difference between doing 6 clicks and 8 clicks.... that being said 200fps is mostly trivial when shooting extreme distances... So in the end I will take the 6.5 X 284 over the 264 Win Mag any day because I get rid of the belt it is inherently way more accurate and my barrel will last a lot longer. My first 6.5 millimeter was a 6.5 x 270wsm (3250fps on a 140VLD not even maxed out!). When I fried that Barrel in very few rounds I decided to go with a 6.5 X 284. To be honest I have not seen enough difference in terminal performance on big game to warrant the 1000 less rounds. They are all still folding in their tracks!
My purpose was not to suggest that any one cartridge is better than another. I was simply answering the posted question of the feasibility of pushing a "hunting weight" 6.5 past 2900 fps.
As to barrel life - I don't see it as a huge problem and certainly the .264WM has an undeserved (in my experience) reputation as a barrel burner. My personal rifle, a Win m70 originally purchased by my grandfather in the late 1960s still wears its factory original 24" barrel and consistently shoots 1/2 MOA 3-shot groups to past 300 yds (which is the limit of my local range). I don't see how I could ask for anything more and the belt also does not seem to be any sort of accuracy handicap.
I would imagine a direct comparison of performance differences between my .264WM and your 6.5x284 would prove purely academic at best.
