Were your wife a 7x57, she would wake you up with a BJ, then go make coffee for you naked, letting you examine her curvature whilst enjoying said coffee, only to really start of your day on the kitchen table.
Then she heads of to her high paying job and comes back at night with your favorite food, cold beer and a new rifle, asking "How was your day?" and saying "Hope, you missed me as much as I did you." really saying: "Lets hit the sack."
Pleasure on oh so many levels - thats the 7x57 Mauser.

There is just no reason to complain.
Wow...does this really happen? Maybe Steelhead could give us an answer!! Doc
I can tell you from personal experience that the 6.5S is a FREAKING long way from the 270W.
If I can't wake my Swede up it WILL BE on the chopping block!
All things being equal, my 6.5x55s generally run 150 to 200 fps slower than my 270 with 130 grain bullets.
6.5x55 with 129 grain Hornady is getting 2,850+/- in a 24" Remington 700. 270 with 130 grain Hornady is getting 3,000+/- in a 22" Remington 700. Of course, I wouldn't load the 6.5x55 that hot for a pre-1898 style Mauser or any Krag.
The 6.5x55 has about 10 grains less powder capacity and a little smaller bore than the .270 Winchester. The laws of internal ballistics aren't going to let the Norwegian/Swede match the .270 with any bullet weight.
But if muzzle velocity is what you're interested in, with 120-grain bullets my custom 6.5x55 with a 21" Lilja gets around 2950 with Norma 204 and VV N560, which is about what the .270 is capable of with 130's in a 21" barrel. And those are with published data, since the Europeans aren't afraid of publishing modern-pressure loads in the 6.5x55.
You might also check out downrange ballistics for the 6.5x55 with high-BC 129-130 grain bullets at 2800-2900 fps. You might be surprised how well they compare to most 130-grain .270 bullets.

M D & 260 -- Thanks to both of ya for your responses.
Yes I understand the Swede CAN NOT equal the vel of the 270 with the same bullet weights. Except maybe ONE TIME! <G>
I'm shooting for +/- 3000 fps with 120 gr bullets, AS you list (MD). Since the 6mm Rem is very capable of 3100 fps w/100 gr bullets AND the 6.5 is a larger bore, the 120s should CROWD 3000 w/o running excessive pressure.
I had to wait 6 mo.s to get 6.5 120 NBTs and now we are having a heat wave, temps 95-105F with index approaching 110 F SO I haven't been able to do any testing.
I'm trying IMR 4831, Surplus 4831 first and THEN I may try to find some N560.
I know a lot of guys use N 204 (MRP)-Rl22 but the VARIATION from temp. extremes doesn't interest me.
260 - I don't have any trouble getting 3100 fps in the 270 w/130 gr bullets so IMO you're a little slow.
My Swede is a Win M 70 XTR w/22" bll.
Some of our guys on the 'fire' don't understand OR NEED a flat trajectory but I'm more than use to it and am UNWILLING to sacrifice it.
140-160s in the Swede can't be shot fast enough to flatten out the 'softball' trajectory. I know the BCs of the 6.5 bullets certainly come into play at long range.
However, most of the time I don't have the opportunity to 1.range, 2. dial mils, or turn knobs. With the 6mm and 270 at 3100fps with their BCs, 400 yds requires NO time to make adjustments. I've been using a sighting system since the days of John Wooters et.al. where even at 400 yds you don't have to hold OVER the back line of a WT.
I really appreciate both of you responding and I'm glad to have the opportunity to express my objectives and why.

PS - My Hot Rodding Days are over (mostly) <G>
The sighting system you have using since the Days of Wooters ? Would that be a Duplex reticle ? Sighted in at about 250-270 yards? Use the bottom duplex/crosshair intersection as aiming point at 400 yards?
My reloading hierarchy is accuracy first, bullet selection second, and speed a distant third. I understand that the 270 can go faster than 3,000 fps, but I don't reload for the 270 and that is the approximate speed that I'm clocking at 10' with Winchester/Olin Power Max Bonded and Hornady American Whitetail factory ammo.
If speed is your goal, there are, as with engines, only two reasonable ways to get it, run it hotter or add capacity. The logical step up from the 6.5x55 is the 6.5-284, as it is a simple rechamber job and you gain around 9 grains of case capacity, 57 to 66.
I have Winchester/USRA 70 Fwts in 6.5x55, my "Africa Rifle", and 6.5-284, a rechambered 6.5x55. Despite having a 22" barrel, the 6.5-284 is the fastest of my four. Despite he other three all having 24" barrels, the 70 Fwt is faster with the same load.
You're close. It's +3" at 100yds which will be +/- +4" at 200, and more or less (depending on bullet & vel) ON at 300 yds. and depending again, -7"--9" low at 400 yds.
Mr. Wooters is the first one that I read with that trajectory. He even had a PICTURE of a WT as a target with circles drawn that you could use in you yard or wherever. I'm 'supposed' to still have that, it was a 2 p spread, and haven't seen it lately.
I know, I know - some will likely rant/rave but ask me if I care. It WORKS for me.
I guess that's something I ASSumed, won't happen again.
Your post seemed to focus on achieving maximum speed and your disappointment in not reaching 3K fps with your 6.5x55. You seem agitated by my post, 'sorry 'bout that, as no offense was intended.
While I may prefer to rank accuracy ahead of speed, I know plenty of people who value maximum possible speed and will gladly accept 2-MOA accuracy if they can squeeze out a little more speed. Sort of like the guys back in the 1970s who bought Kawasaki H2s instead of Norton Commandos or Triumph Tridents. Both roads got guys from here to there, they just got there in a little different manner.
I don't accept a 'load' that is only capable of 2" @ 100 yds. either. I really mean that velocity w/o accuracy IS useless. What good does it do to GO 4000 fps and you can't hit your target at let's say 400 yds.
I strive for the 'best' accuracy I can get WITH the most vel.
