No one has mentioned the 6.5x55 Swede which will shoot along side or faster than the .260 with handloads and Ackleyized will shoot along with the 6.5/.284 with out the feed problems of the rebated rim.
I thought of it as well as even the 6.5 jap but when he mentioned "cheaper to shoot".. I discounted it.
Without the First and Second Amendments the rest of The Constitution is Meaningless.
If your gonna reload, the 6.5-06 would be better for a repeater then 6.5-284. I would also look into a 6.5-06 AI, 6.5 STW, 6.5 WSM, 264 and the 6.5 Rem Mag. all great rounds, just pick your poison since they will all do what your asking of it.
I am thinking about a 6.5 build, either a 6.5 weatherby magnum, 6.5-284 Norma, or 6.5 creed
I am leaning towards the 6.5 weatherby as it is pushing the new berger 140gr at 3300fps with BC of 612, but the 6.5 norma is intersting and little cheaper to shoot.........thoughts??
not sure if your leaning towards the 6.5/.270mag version or the 6.5/.300 mag design, but the 6.5/.270mag case will push a bullet right at 3300fps with a lot less powder than the .300mag case. I push 140 grain bullets at 3300 fps in my 270 mag (pretty hot!). Might also look at the 6.5-06AI, as this round really gets it done
