I think your idea has considerable merit, but then I've been a died in the wool 6.5mm shooter since 1962. I picked up a Model 94 in 6.5x55 before headin' west. Took a couple of nice mulies bucks, then in a moment of weakness sold it.
I replaced it with a Type 38 Arisaka, chambered for the 6.5x.257, a wildcat with similar powder capacity, than hunted in the Yukon with a couple I went to high school with. Had no trouble takin' a couple of nice caribou bulls.
Then I met a guy who was a shirttail relative of some ranchers in the Chama, NM area. We were young and were sent into the timber to chase the elk out to the older folks. I managed two ragheads and 3 cows, all with 140 grain bullets, my pard had a 6.5 Remington mag, and with a 129 Hornady, killed a cow faster'n any thing I'd seen.
I played with a 96 Swede, but it wouldn't shoot no matter what I tried. Had an old Belgian Mannlicher in 6.5x53, but it was a bit to moderate for my purposes. Built a 98 Mauser to .256 Newton, and it wasn't any better'n the 6.5x55. Lastly rebored my old Savage 110L from .243 to a cartridge called .263 Express in those days, now recognized as .260 Remington. Rechambered a Type 38 to .260 for a brush gun, and find both rifles prefer the 129 Hornady, but still shoot the 140s. The Savage has an 8.5" twist, and will shoot the 160 round nose bullets quite well, The Arisaka will shoot the 160s good enough for the black timber. Now I'm usin' it here in TN for white tails, hogs, and black bear, it killes 'em all sudden like, if you can put the bullet in the vitals. Recoil is mild enough so you can concentrate on the shot, and not holdin' the rifle just right.
