What rifle calibers will compare with or exceed the numbers of the 6.5 x 55?

I guess what i want to know is, What is out there that is as good or better than the 6.5, easy to get ammo for and leaves your shoulder still intact after multiple shots?

Do you want to stay in 6.5mm? Better for what? hunting? Target shooting?

If you give us some more info we will be able to answer you better.

I'm guessing that you still want it in 6.5, but with a little more power.

If that's so then you've got the .260 Rem, the 6.5 - 284 Norma, the 6.5-06 and/or the .264 Win Mag.

That's about it if you want a little more velocity and power in a 6.5 diameter cartridge. There's also the 6.5 Grendel, but I believe that it's going about the same speed as the Swede or maybe just slightly higher.

If you're just saying that you want something larger than a 6.5 altogether, then the sky's the limit.

Here's some links for you.

There is also the new 6.5◊47 Lapua, which is about the same as .260, but apparently with better brass. Its also a short action round.

Also there are AI versions of several of the 6.5 rounds, which add a few fps but may not feed as well from a magazine.
I personally would pick the .260 in a short action, or the 6.5x55 in the long action. This seems to be a great compromise between ballistics (beating most .300 win mag loads), and barrel life (3000+ rounds).

Like people said above the .260 rem, 6.5x.284....are all choices but unless you want to pay out the ass for a custom barrel or gun the 6.5 swedish and the .260 rem are your best choices. The swedish may be a little easier to find ammo for, but the .260 with factory loads will give you slightly high velocities. If you hand load you can match and do better than the .260 with the 6.5. I believe that factories make their loads able to be fired out of mil surp firearms and have to lower the pressure, but out of a new gun you can load to slightly higher pressure.

The .260 seems to be a great cartridge and growing in popularity. It will probably become more common and more available over the next few years.

I have a swede mauser that i love to shoot. Very accurate, shells are fairly cheap, and it does not wear you out. I really like this caliber and the numbers it gives. Not the fastest, but makes up for it with its high BC.

I want to get another rifle for hunting, paper or whatever else comes along, but mostly hunting. I have a lonely scope that needs a gun.

I was wondering if there was anything out there in or around the 6.5 catagory that I would like as much as the swede.

Or should I stick with the swede and get another one.........in a modern gun

As others have stated, the 260 Remington would fit your needs nicely. Also, the 6.5 Grendel is an amazing little round. It uses a very efficient case, and has low recoil. I can shoot mine all day, and now that Wolf and Black Hills are making ammo, it is getting less expensive to shoot and we are getting more variety.

Look here:

Does the grendel come in bolt action?

How do the numbers compare with the swede?

<Or should I stick with the swede and get another one.........in a modern gun>

Well, that's what I would do. My sporterized M96 (barrel cut to 24" like a M38 and a modern stock added) is about the most versatile, soft recoil, flat shooting, wind resistant all around hunting cartridge I can think of. But the gun was made in 1899 and I'm just not gonna take a chance with really heavy loads. A modern gun in this caliber made with modern metallurgical techniques should allow custom loads of even greater performance.

Heck, there are even those who feel that the old 96s can actually stand up to modern loads but I would hate to damage my poor old Carl Gustav.

Stick with the Swede. It's tried and true and these other cartridges don't do anything it can't do with a modern gun and suitable handloading.

I'm not knocking the other 6.5s, I just don't think they're necessary.

Just my opinion.

You can get 6.5 Grendel bolt actions but they are not factory items. You would have to have one made. If you look on the 65grendel.com website there is a lot of info, and you can look in the "bolt action" forum.

The 6.5 Grendel's ballistics are about the same as the 6.5x55's, maybe a few fps slower, but where the Grendel excels is that is a lot in a little package. With the same overall length as the .223 Remington, you can duplicate your 6.5x55ís ballistics. Pretty cool, huh? Itís short, fat case is very efficient and requires less powder (and less pressure) to achieve the same velocity

6.5 Swede is hamstrung by its low "spec" max pressure, as a result of ancient rifles. Based on case capacity, it should provide ballistics close to 6.5-284 Norma if loaded in a modern rifle built for it. In other words, a 139-142-class bullet at 2900-3000 fps.

As has been indicated previously, with handloads in a modern rifle, you can ignore the artificially low pressure specs that the Swede is hamstrung with due to the Norwegian Krag being chambered in it. I have used the 6.5x55 for 1k F Class competition for several years now, and I can safely run 139-142gr match bullets at 2925-2950fps, depending upon which powder I use. Since 2950fps is what most guys run their 6.5-.284's at, the Swede gives up nothing to them.

I would think that the creamy 6.5 goodness in a .308 shell would make for a sweet setup.


ETA: Yes, I'm referring to .260 Rem.

Currently, I have a Grendel upper and this sweet CZ 550 American I just bought from a guy. :D

It's called .260 Remington, A cartridge that to date has largely been a sales failure

.260 Remington is becoming one of the most popular cartridges for practical long-range shooting.

6.5x47mm is a cartride designed to be equal to the 260 but with a shorter case (260 is 6.5x51mm), and therefor higher pressure. The shorter case allows for longer bullets that don't intrude into the powder in short action rifles. The brass is made by Laoua and is very good quality. The 260 brass made by Remington is of inferior quality. IIRC, the 6.5x47 uses a small rifle primer.

6.5 Grendel is much slower than the 260 and 6.5 Swede, and was designed to fit into M16 magazines. It's basically a 6.5 PPC, based on a blown out and necked down 7.62x39. It has the same 0.450 case head of the 7.62 russian. The best project rifle for conversion is probably the CZ-527 carbine, which already has the right extractor and bolt face. A remington conversion is not trivial.

You can convert a 7.62 CZ with little more than a barrel swap and there are several gunsmoths that will do this for around $400. The 6.5 Grendel is far superior ballistically to the 5.56x45mm, 7.62x39 and similar catridges.

The 260 remington bests the 6.5 grendel by about 300 fps.

But to get back to the OP, .243 is more available, very easy on the shoulder, and will take down whatever you're shooting at in your area.

I got three repeat calibers in my collection: '06, 7.62x39 and 6.5x55. Hands down my favorite.

My commercial gun is a Rem 700 Classic. Nice, pretty accurate halfway cheap gun. I have no complaints at all. Granted, the CZ's with the full stock just look so sexy, it's probably gonna be my next commercial gun purchase.

You can also get 260REM brass from Nosler. It's expensive, but good.

Rumor is that Winchester will be offering 260REM brass sometime this year.

6.5 Gibbs
6.5 WSM
6.5 WSSM
6.5 x 55 Swede NO Throat
6.5 x 47mm Lapua
6.5 Gren Match

(The list from Pac-Nor, minus standard cartridges and .260AI)

My favorites would be 6.5-06 (aka: 256 Newton which was once a factory cartridge, and 6.5-06 A-Square) and 6.5-06 AI They're almost .264 Magnum speed, can be created from .270 Win Brass, can shoot Berger VLD(s) with BC(s) in the .6(s). Practically no recoil. Get a Savage though, so you can change the barrels yourself. They last about 1800 rounds in the 6.5-06s.

6.5x284 isn't bad though. Never had a .260

How accurate will they be at 1800 rounds, that seems like the barrel should last longer than that.

Might still shoot MOA, but the throat will be going. 6.5-06/256 Newton is like a 6.5x284 in barrel wear. Don't shoot 'em cherry hot, a target gun could last longer. A hunting gun could last half a lifetime.

Barrels are like tires though. If you shoot a lot, replacing a barrel is a good thing. I know folks who replace 6mm PPC barrels at 800 rounds, and at that point, they probably shoot better than most factory guns will ever shoot.

There is nothing nicer than having a new Shilen, Pac-Nor, Hart, or Kreiger on put on your rifle.

For a non-competition gun, get a Savage. You don't need a gunsmith and can replace the barrel yourself in 15-20 min. Perfect for a 6.5-06

The throat may be wearing and accuracy dropping but I honestly believe they will still do for most purposes. The rilfe may go from shooting .3" groups to shooting .5/.6" at this point but should still be more then accurate enough for all but benchrest or ultra long range varmite for a couple thousand more rounds at least. I`d hazard a barrel to go 3-4000 rds with sub MOA accuracy with the 6.5-06, 6.5x284, ect, maybe more if properly cared for. That`s in the same range as a 270 Win, 7mm Rem mag, ect.

My friends who shoot 7RM for field-style long-range stuff see accuracy fall off dramatically at 1750-2000 rounds.
