Which of these calibers would be the most suitable for 500-600yd target shooting from a non heavy barrel 7-8 lb.rifle.
Other caliber suggestions welcome.
None that kick harder than a 308.
I plan to compare one with a yet to be acquired 257 weatherby.
thank you.

Unless you do something like this in a 6.5-284-http://www.eabco.com/9702.html

The king of short range target shooting these days is the 6BR or one of the variations 6BRX and 6 Dasher.
This is a mild but very accurate cartridge when the driver and his equipment are up to the task. Norma has target loads for the 6BR but you will want to reload to keep costs down and get the maximum enjoyment from the shooting.
Savage has 5 bolt action models chambered for this cartridge and one in particular which is nearly what you describe. Besides, if the 6BR doesn't pan out for you there is always the 6.5x284 barrels available for this rifle also.
Best.
Mind you the 6Br is a fine cartridge, i've a few friends who have them, they are fun to shoot.

Only if you're looking for .284 Winchester brass from Winchester. In there inimitable wisdom, Winchester has placed the .284 Win. brass on the 'seasonal' manufacturing list, which means that it gets produced once year and in one run. Once it's gone, it's gone until the next run.
Thanks to the companies like Norma, Lapua and Hornady though, we're able to get 6.5x284 brass ready to shoot. It's expensive but what brass isn't?

Yes, and it holds every major record at 600 yards and a couple at 1,000 yards. I'm even shooting one version in an AR15 semi-auto target rifle.
Best.
A great thing is the 6BR case can also be used for the 22BR and 30BR.
I have a Encore barrel in 22BR caliber. It can shoot almost as fast as the 22-250 but burn 10 grains of powder less per shot doing it.
The same parent case can be necked up to 30 caliber creating the 30BR. I have it on my dream list and will get one as soon as I am back on my feet financially.
The barrel life on the 30BR is over 7,000 rounds in competition. It shoots 118-125 grain 30 caliber bullets into little tiny holes.
One case, three cartridges, what else could one ask for??

To answer your question the 6.5x284 is more suited.
BUT if I were you I would look into the 6.5 Creedmoor![^]

First, the question hardly relates to the last statement. The .257 Wby is a great cartridge in it's own right, but not really top 500-600 yd. competition material.
Getting down to brass tacks. I'm assuming you will want a competition rifle. Rifles that aren't dialed in just become a frustration, because you can't accomplish with the rifle what you can see you need to do in your mind. That said, in a direct comparison, I think you will find the faster 6.5-.284 with better BC's on their bullets easier to shoot better scores with @ 500-600 yds. than a .308. You will also find there is a price to pay, and that is barrel life. The 6.5 wears out a lot faster than the .308. Both have decent match ammo made, but it's expensive. Reloading is the way to go for most anything, IMO.
As far as off the shelf paper punching, .260, .243 and 7mm-08 are all good. To get the most potential from any of them, you need to reload. .223 is an excellent cartridge also. It's the only one that might be economically feasible without having to reload. It's tougher to call in wind, but in any gusting wind, they all get much harder to call.
Moving to the newer/wildcat cartridges, the 6mmBR is the latest craze to hit the market. It's been around since around 1980 but really took off in the last five years due to the expanded interest in 6mm and especially the bullets now made in 6mm that optimize for long range shooting. I'm speaking of the 105gr., 107gr., 108gr., and 115gr., long, needle-like ogive bullets.
As nononsense stated, these own almost all 300, 600 and a few 1000 yd. records. Very little recoil combined with a high efficiency bullet makes a very accurate rifle even more accurate in the hands of a shooter who doesn't react to recoil after long strings of fire from one. These and the 6mmXC/6mm Creedmoor are about a perfect a size case as you can get for the 6mm caliber. The .243 is a little bigger but in using more powder, creates more wear on the barrel. The .260 remains optimal for high BC bullets and speed. The 6.5 Creedmoor is about the same, has match ammo. When you get up toward the 7mm, you are starting to take a hit on velocity. But that is offset by even better BC's of the bullets, evening up the comparison a bit.
That still all boils down to how well you learn to get out there and practice and get good at shooting that far.
zero 200yds, same drop @ 500yds..down to preference.
