BBerg,

That's because I've not only shot a number of CZ's with long throats that are VERY accurate (my 9.3x62, for instance, will group almost any bullet into less than an inch, and often 1/2") but because of all the Weatherbys I own that shoot 1/2" groups despite their "freebore."

If a long throat is just slightly over bullet diameter, then the rifle will typically shoot extremely well.

If you look at the common 6.5mm/.264" bore cartridge hierarchy;

The 6.5x55 has more capacity than the 260.
The 256 Newton has more capacity than the 6.5x55 and the 260.
The 6.5-06 has more capacity than the 256 Newton, 6.5x55, and the 260.
The 6.5-06AI has more capacity than the 6.5-06, 256 Newton, 6.5x55, and 260.
The 264 Win Mag has more capacity than the 6.5-06AI, 6.5-06, 256 Newton, 6.5x55, and 260.

But only the 260, 51mm case, fits well in short actions. If you're going to go with a long action, why not maximize the performance potential by going with a larger/longer case than the 6.5x55?

Remember that "better" is never a subjective measurement, but capacity always is.

You said it better than me, but you are spot on. Arguing the 6.5x55 is better than the 260Rem is a pretty futile argument.
No Game animal will ever know the difference, and the 260 Rem is the only short action of the bunch. Were I to ever want to shoot a 160 grain 6.5 bullet, the 6.5x55 would be my "last choice".....

This thread has seemed to be about capacity, using water. I have some old Barnes 6.5mm 165g original bullets. They are 1.3680" long. Seat them in your 260 Remington COL 2.800" then seat them in a 6.5X55 with a COL of 3.150. Get both to fit the magazine and the throat/lands of the rifle. Which one do you thing will have more useable capacity in the case for powder? The 260 is a great round, is the 6.5X55 better? Only if you want to shoot really heavy long bullets. Does one need to do this? Don't know, we could build long action 260's with a long throat, or 6.5X55 on a few selected short actions. It's a rifle looney thing.

Jeez, this argument is still going on? 26 days, 3700 views and 7 pages later and still no resolution. Heck, I'd have a .270Win. barrel shot out by now!! laugh

Now back to regular programming.

Bottom line.....ballistically they are virtually the same but the Swede is waaaaaay more sexy. Sexy is good.

bigwhoop: Yeah, much ado about little difference.

I have been considering a 260/6.5 BUT I don't need more OCD.
My 270 has a 260 IN IT ! LOL

On and on and still no consensus ..... next up is the 7-08 vs. 7 x 57. I'm sure it hasn't been done before... (smiley face, if I knew how to put one of the damn things in)

Im sure all the same people that think my 6.5 Swede is a futile waste for being forced to lug around the burdenous looonnng action as compared to the virtuous 260 in the righteous short action, will think im equally wrong for this............

Clearly the 7x57 is superior to the 7-08.

OK, my name is Tom & I'm a rifle loony. Here's my problem: I have a long action Husqvarna 30-06 in a california style stock. Rifle works OK, but I never cared for the stock style and I am contemplating a rework.
Can anyone come up with a reason to go with 260 instead of 6.5x55? Or is the rifle (one of those with the dovetail shaped locking lugs) not worth the expense of this mod?

Does the bolt face need to be modified for 6.5x55?

I have 2 model 96s and a modified model 38, so I have the 6.5x55 dies.

Thanks for your help.

If you have 6.5x55 dies and components, and a long action there is no logical reason not to do a 6.5x55 over the 260. The bolt face should need no modification. However, since you are a confessed loony among many others here, logic need play no role in your decision. wink

If you don't like the stock, Hansen & Hansen in CT had some stocks for sale awhile back. The Husqvarana 8000/9000 style actions are great, I have some in their original factory specs and 2 that have been rebarreled to 256 Newton and 338-06. Since your rifle has a long action, it seems reasonable to rebarrel it to a long action cartridge, and although I am a fan of the 260, I don't think that it would be the best option in your long action rifle. My favorite long action 6.5mm bore cartridge is the 256 Newton, but forming cases is a PITA, so I never recommend it to others. There is always the 6.5-06 if you're seeking more speed at safe pressures.

FTR, I am not advocating that anyone do, or not do, business with H&H, just that they might have a stock that would better suit your needs. You might also contact 24HCF member SBHVA, since he is the resident expert on all things Husqvarna.

Thanks for your help. Now I need to check with pac-nor and get in line.

I was amazed at how fun the 6.5s were to shoot. The 260 opens up the short action market. They are both tools for the those who rely more on skill than muzzle blast.

I recently picked up a '55 vintage M70 fwt in 270, so I can finally emulate my boyhood hero, Jack O'Connor. Life is good.

I have a 1st Model Newton, SN 3xx, and a Husqvarna custom.

The 256 Newton is a nice cartridge. Like JO'C said of the Newton cartridges, "The next generation's cartridges today". Since Newton was active about 100 years ago, I wonder what he would think of cartridge changes since then.

If you have a long action in need of a caliber change, go with the nasty uncle to the 6.5x55. Get a 6.5x284 barrel and add 300fps to those 6.5x55 bullets.

Here we go again.

When handloaded (and most people who post here will handload) the 6.5x284 gets AT MOST 150 fps more than the 6.5x55 with 140 grain bullets AT THE SAME PRESSURE.

This is due to the 1/4 Rule of internal ballistics, which states that any increase in powder capacity results in only 1/4 of that amount of increase in muzzle velocity.

The 6.5/.284 Norma holds about 60 grains of powder with a 120-140-grain bullet loaded. The 6.5x55 holds around 50 grains. This 20% difference amount to a 5% difference in potential muzzle velocity.

The 6.5-284 is capable of right around 2900 fps in a 24" barrel with a 140-grain bullet, while the 6.5x55 can get around 2780-2790. This is with published, pressure-tested data for both cartridges.

Additionally, the 6.5x55 case will normally feed perfectly in any .30-06 length action without any modifications, while the 6.5/.284 often requires some gunsmithing to feed smoothly, especially in a controlled-feed action. Though the 6.5/.284 will normally feed easily in a push-feed action.

The 6.5-06 has just about the identical powder of the 6.5/.284, and is capable of the same velocities. It will also work smoothly, of course, in a .30-06 action, if going to the trouble and expense of a wildcat is worth that extra 125 fps.

I have shot both and enjoyed both. For now I have settled on the 260rem and like I said in another post somewhere else, if I need a heavier bullet I grab a different rifle.

One thing is for sure though, I would never be without a 6.5cal rifle, be that 260rem or Swede. With two boys growing up quickly, I figure the 6.5 is spot on for those grasshoppers :-)
