Your 6.5x55 has that in the bag in a modern rifle
That IS a fact.
From the land of 6.5x55 (Norway), 2950fps is within reach without problems, be the barrel 28" ish or so.
In a sporter barrel you may have to settle for 860m/s, and over here a lot of (most) people hunt moose with it, and some even with cut down barrels of 45-50cm (18"-20") - this will get the fps down to 800ish m/s
I use a muzzle brake
on mine when i shoot it off the bench, and sometimes also in the field with bipod. Shooting 139gr Scenars the recoil is more like that of a .223, my son shot it with full loads when he was 5, and suffered no ill effect. When hunting i use a suppressor, it saves my ears, and allows me to spot impact.
I have had a 6.5-284, several 6.5x55s, and nearly all my friends shoot 6.5x47, .260 or a 6.5x55. The .260 will NEVER give 6.5x55 velocity, and the x55 will never give -284 velocity. All the stuff aboput 260s shooting as fast as ax55 is purely higher pressures, and in a similar rifle, with similar brass there is no reason for not using them with the same pressure.
VV N570, well compressed, is what will yield the highest velocity from a 6.5x55 and 140gr bullets, but Norma MRP og MRP2 (though ridiculously expensive) is right up there and is less work both cleaning, and at the bench getting it into the case...
On moose i have used Swift Scirocco IIs and Swift A-Frame, these are hard bullets and i will be changing to the Berger VLD Hunting as this has given me better experiences in .308Win - a lot of people here swear by the Nosler Accubond for LR-work on big game.
