I keep going back and forth on keeping a 6.5x55. Can anyone tell me what the figures are for this caliber? (Velocity, bullet weights, etc.)

Also, what ammo companies produce this load? I don't handload, so would need factory ammo.

What is 6.5 - approximately .243?

Thanks.

Bullet weights around 120-140gr, I think there might be specialty ones heavier and lighter.

Velocity is rather mundane, the trick to the 6.5 Swede isn't blistering speed, it's the insanely high ballistic coefficients of the bullets themselves. They don't need a whole lot of speed starting out because they retain most all of it and penetrate deep for their weight.

Factory ammo can be found by Remington, Wolf Gold, and the cream of the crop Lapua and Norma (which you'll be paying out the nose for.) You really should look into reloading, as case life is long due to lower pressure.

Thanks for the info. Maybe I'll keep my 6.5.

My 6.5 is a CZ 550, which seems like a classic rifle for this caliber. (I almost forgot, I also have a Swedish M96.) I've never fired either, but I kind of like the idea of an intermediate cartridge, that doesn't have a lot of recoil. It might also be a good caliber for my daughter and wife.

~2550 fps, with a 140 grain bullet. What other calibers are in this ballpark, in terms of recoil, etc.?

Thanks again.

It's not so much the BC as the sectional density. The 140-160 grain loadings have extremely high SD numbers and will penetrate like crossbow bolts. They tend to hit far harder than the ft. lbs. would suggest. The round is considered fine for Moose.

Modest velocity, high sectional density, low recoil, accurate. It makes a much better choice for most hunting applications than our home grown .30-06 or .308 Winchester.
The only bad thing I can say about it is lack of quality guns chambered for it.
Most commercial ammo is rather sedate as the older '96 action is weaker than most bolt designs chambered for them. Norma ammo is quite hot and designed for modern bolt actions.

How did the Swedes develop the 6.5x55 cartridge? Did they have long-range ballistics in mind?

The Norwegian and Swedish developed the 6.5x55 as a military cartridge [ 1894] it takes bullets from about 77-160 grains .Unfortunately the ammo makers here have dropped the pressures due to the old rifles especially the single locking lug Krag rifle of Norway. So I feel today it's a handloaders cartridge.I have used it for many years as a deer rifle and agree that it is the perfect deer cartridge. Handloading , in a modern rifle can get 2750-2850 fps at reasonable pressures with the 140 gr bullet. This I think is the ideal bullet because of it's high SD and BC it really holds velocity well . It's also an exceptionally accurate cartridge and is used as a target cartridge in Europe.While a few use it in Scandinavia as a moose cartridge it is the minimum permitted and the moose are smaller than ours.It does it's work without much recoil , muzzle blast , velocity.

I bought my son his first centerfire hunting gun in 6.5 Swede, and it's been a keeper fer sure, fer sure. I'm continually impressed with it's accuracy and terminal performance on game.

I ordered my first 6.5x55 SE rifle in August of 2005, and I received it in February of this year. I bought it for antelope hunting. It has produced two stunning groups using my hunting load, and took my antelope on October 1st with a single upper-chest shot. I love this cartridge! The rifle is a Cooper Arms M22 Phoenix with a Leupold VX-III 4.5-14x40 LR scope with Varmint Hunter's reticle. Some photos:

Good post, mete. I will only add through experience, that in a modern rifle with safe pressure, you can go as high as 2950fps with the 142SMK bullet. And, the 6.5x55 is used as a target cartridge in the US as well (1,000 yard F Class competition).

Don,
What lenght barrel are you getting those impressive veliocities out of......?

mete
October 27, 2006, 12:30 PM
The Norma load for many years was 2788 with the 140 and 24" barrel and Norma 204. Then that was increased to 2850 with Norma 205. 2950 would be pushing the pressures a bit. BTW my custom M98 with 24" barrel barely warms the fired case. Mine is also chambered for the very long 160 gr which means a good bit of freebore....2950 would be more typical of the 6.5-284.

I agree with mete that this is a handloader's caliber. I don't think the caliber really needs maximum velocity, but factory velocities are WAY too low and don't allow you to take full advantage of the excellent BC's. For example, I worked up a mild load for my wife's Sauer 202 that is a 140 grain Nosler Partition launched at 2620 fps. (She used it to bang flop her antelope this year, and she would use this same load if she can get a shot at an elk.) I chronographed some Federal factory 140's, and was getting 2386! I love the caliber, but, if I were limiting myself to factory ammo, I would get a .260 instead. The .260 is a modern 6.5 cartridge that is factory loaded to modern rifle pressures.

My own 6.5-06 sends a 139gr Lapua Scenar downrange at a hair over 3000fps, so yes, Don is pushing things with his custom 6.5x55 Winchester Model 70. He posted earlier that he's using one of the slower Reloder numbers as his powder of choice, and that gorgeous Model 70 of his has a fairly long barrel to make best use of all that slow powder. Nor would his handload be a good one to run through a small-ring 94 or 96 Swedish Mauser. ;)

I've heard rumours that the downloading of the 6.5x55 is due more to the Krag than the M96. Has anybody every actually gotten a m96 to spontaneously disassemble itself with normal loads (no bullseye filled cases)?

GTSteve03
October 27, 2006, 10:38 PM
I've always heard the M96's were factory tested with a double-charge to make sure it held. I would think this would mean it still has a pretty hefty action that should handle most reasonable hot loads.

of course another beauty of this round is that, if you go to gunshows, you can find lots of new mfgr boxes of this stuff from 110 to 140 grns, plus wolf now makes it, best of all , there is plenty of milsurp to be had as well. At the houston shows, I see it typically for about 7 bucks a box. And it us usually swedish mfgr, so it is plenty accurate. i would think, that if handloading, with a good new action, such as cz, you could get speed approaching the 3000 mark, without sacrificing accuracy. And if you really felt naughty, you could allways step up to the 6.5/284.

That's a 28" Obermeyer. Gewehr98 is correct, loads like this are not for the '94 and '96 Mausers.

Swedes did proof there guns.

What's weak about the 96 in comparison to a 98?

I wonder if there is any merit to this, or if it is just something that everybody has heard from somewhere else? Kinda like the CZ52 being so strong, when in fact they are more likely to blow up in your face than just about any other pistol.

The little triangular stamps impressed on the disk are inspectors' marks indicating the condition of the bore. One section of the disk, the smallest, contains just the numbers 1,2, and 3; that measures the surface condition of the bore in terms of wear, with no mark being best and 3 being worst.

The other, larger section of the disc indicates the actual diameter of the bore. There are two rows of numbers, one above the other. The bottom row starts with the number 6.46, followed by a 7 (meaning 6.47), an 8 (6.48), a 9 (6.49), and a 0 for 6.50. The top row begins with the number 6.51, followed by a 2 (6.52), then 3, 4, 5, 6, 7, 8, and finally 9 for 6.59. In the pic you can see the condition stamp at 1, and the bore diameter stamp at 6.50.

From what I can gather, being a high pressure or low pressure action has more to do with the metalurgy than the presence/absence of this third lug.

However, if bad things do happen...then I suppose the third lug is nice. Didn't Mauser have a bad kaboom, and then became more safety conscious?

I am wondering about the probably of it happening, not what does happen if it does. The third lug is a safety feature, not a primary functioning part. From what I can gather it doesn't actually add to the strength, it just keeps you from eating the bolt if the two primary lugs fail.

Limey;

The answer to your question pretty much lies within the information about the Loopy scope. In other words, a Leupold Rifleman retailing new for $200.00 is a vastly different chunk of glass than a $500.00 VXIII.

It sounds, on the face of it, to be a fair to very good deal. If you ever find the same gun in left hand bolt, please tell me.

I saw a picture post on anothersite a few years back where some goofball who didn't know what he was doing filled a 6.5 swe case with bullseye- he figured that if the powder was safe in pistols, a rifle shouldn't be a problem:rolleyes:

The result was a ruined M96. What impressed me was the limited amount of damage to the rifle considering what he had loaded in the cartridge- the bolt was sprung upward, but still in the receiver, the stock was split, the receiver was somewhat mangled and twisted, and the shooter had what looked like roadrash on his left forarm.

It impressed me that the rifle didn't completely grenage on the shooter and kill him, but held together more or less. Seeing those pictures gave me a lot of confidence in the strength of the 96 rifles, though I don't think hotrodding a 100 year old rifle is a smart idea.

You may be able to enlighten me on something. I've got a 96 with the big adjustable receiver sight, the hooded globe front sight, and the detachable wooden pistol grip. Does this variant have its own model designation?

And is that thing you're using on the Mark 32 scope turret the real, genuine, proper armourer's tool?

Its most likely M96 converted to a target rifle, probably for a civillian marksmanship club.

There are factory target rifle variations such as a CG63 and CG80, but they have an entirely different stock on them altogether.

Is there any significant difference when it comes to ballistics and loads for different barrel twist rates? I've heard that the swedish mausers have a 1 in 8" rate but most commercial rifels are 1 in 10". I'm working on loads for my sporterized M96 and it has been reccommended that I stick with heavier bullets, 140 & 160 grain, for the slower twist rate. I'm new to this caliber and rifle so any help is appreciated.

On the subject of sectional density and ballistic coefficient, my 'range' at the farm is 800 meters from bench to berm. In the berm are several 50 plus year old pine trees with circumferences of up to five feet.

It was a given that any 6.5x55 FMC or RNHP round of Hansen or Federal 139/140 grain would fully penetrate the treetrunk up to that distance.

Yeah, it does dig deep. I have 3 Swedes.

This is from http://www.tfd.chalmers.se/~m95perm/vapen/eldhandv/disk.html:

The "one screw type" brass disk

The larger sector tells the actual calibre of the bore.
A triangular mark is made above the "hundredth of a millimetre digit",
e.g. a triangle above "4" in the outer group of digits means 6,54 mm,
and a triangle above "9" in the inner group means 6,49 mm.


The second largest sector tells the difference between the point
of impact and the point you are aiming at -
when using the "new" pointed m/41 bullet.
"Torped" is a boat-tailed, pointed bullet.
"Íverslag" is over.
"str" is an abbreviation for streck which is a unit for plane angles,
there are 6300 streck to a circle,
and 1 str makes approximately 0,1 m at 100 m.
So if it say "2" on the disk you will hit 0,4 m above the point you
are aiming at, at a shooting distance of 200 m,
that is - if you are using the Swedish Armys m/41 ammunition.



The smallest sector tells if there is any rust in the barrel.
A small triangle above "1" means visible signs of rust,
above "2" more rust,
above "3" rusty but still acceptable
Note that "3" does not mean poor condition, the Swedish Army never used
weapons in poor condition.

If there were more rust, or if the diameter of the bore
- at the muzzle end -
was bigger than 0,06 mm over the calibre stated on the brass disk,
or if the diameter of the bore was bigger than 6,56 mm,
the disk was removed and red sealing-wax was poured in the hole.
The rifle was then sold, or sent to an arsenal to be rebarreled
(during WW2 often into an m/96-38).

If the diameter of the bore was more then 0,03 mm,
but less than 0,06 mm, over the calibre stated on the brass disk,
the rifle was used only for training.



There are actually five grades, or classes, of deep seated rust,
or pitting corrosion in the barrel.
0 Absolutely no corrosion, abrasion or scratches
- As good as new.
1 One or just a few dark areas in the corners
between grooves and lands.
2 Rust in the corners between grooves and lands,
some spots of rust in the grooves.
3 Spots of rust throughout the whole length of the bore
but no sharp edges.
4 Sharp edges between corroded and not corroded areas
- Discarded.
