6.5x55 sweed

[sgt_zim]

Coincidentally I have never owned a .270.

Now, I see this along the same lines as the .25-06, the .270 diameter projectiles are unique to a small range of cartridges.

Well that’s from what I can see . With just 7 thousandths of an inch difference again if .280 gained popularity would we need the .270

But this is coming from someone who wants a 6.5-06 to be a standard over the .25 calibre .25-06 and who uses a 7mm calibre in preference to the the .270 wincHester.

For just seven thousandths of an inch difference the is probably duplication in performance in those .30-06 based cartridges.

But I have a 6.5x55 a .280ai and a 7x64 and would like a .260 rem so my bias also comes from wanting to stick with 6.5 and 7mm variants because otherwise I would be trying to keep a range of .25 and .27 cal projectiles.

Performance wise I’m not splitting hairs for what I do but just favoured the cartridges I chose.

Or imagine that they'd made the 270 with a 9 twist barrel from day 1.

I can’t comment on that. I haven’t seen bee given the .270 serious consideration or compared the specs.

Nothing against the .270 but I went with .308 as my first hunting rifle cartridge .

The good old 6.5X55 will do nicely thank you!

With a 9 twist, I believe they'd be able to stabilize 170 or 175 gr pills, instead of being limited to 150 gr pills I consider marginal for anything bigger than a mule deer.

I agree the 260 rem is limited to coal due to the short action. I still think it is better than a 243 and is a good cartridge but as you say 120-139 ran grainers are really about all it can handle well.

@dlmac
A bloody air rifle is better than a 243.

@CBH Australia
Chris a 25-06 or a 257 Weatherby with a 1:8 twist for the long 131gn bullet would be a devastating long range round especially out of the Weatherby at 3,000 fps

Totally agree with you except on 280 AI. In 7mm cartridges, 170 - 175 bullets are king. Usually pretty good to great BCs, with SD at .3 or higher, but at more modest MV of 2700 - 2800. With a good bullet like an A -Frame, North Fork SS, Nosler Partition or Accubond, it's a great cartridge for both near and as far as I really care to shoot, 400 yards under most conditions, and 500 under ideal conditions.

And I get 1 more round in the magazine relative to 7mm RM. Better to have and not need than to need and not have.

Hi sgt_zim,

Myself not being a fan of PO Ackley’s chamber modifications, I’ve never been tempted to own any of them.
I have fired two different fellow’s, Ackley style re-chambered rifles, (at inanimate targets).
One was a .257 Roberts so re-chambered and the other was a .30-30 Winchester, likewise re-chambered to Ackley’s sharp shoulder, plus almost no cartridge taper.
I shrugged.

Even with that, I have to agree with you that, among the long list of Ackley modified chamberings, indeed the .280 rechamber is the one I would choose, if I was in the market for one of these ultra-light rifles, so popular with hunters of the various high mountain wild sheep species.
And, if the 7MM Remington Magnum had never come along.

That one is definitely not super efficient, compared to the regular .280 and 7x64 or the .280 Ackley.
(Neither is the .30-06 very efficient, when compared to the .300 Savage).
But, I like the 7MM Magnum (and the .30-06 for that matter).
The 7MM Remington Magnum is my 2nd favorite long shooter for hoofed game, in wide open conditions.

However, I do not hunt those expensive high altitude sheep species, not to mention that my skeleton is rebelling against me (arthritis), now that I’m in my 70’s.
And so, an ultra-light rifle is not in my future.
I repeat that I do agree with you on the .280 Ackley.
It’s a good one, even though I personally don’t believe I’ll ever need one.

Be that as it may, I repeat, the Ackley .280 is a pretty good one.
It is close on the heels of the 7MM Magnum and reportedly recoils a little bit less, probably due to less powder being burned.
Plus, as you mentioned, the belted magnum holds one less cartridge in the magazine of comparable .280 rifle repeater designs.

So, even though a .280 Ackley would not really benefit me at this stage in my life, I do understand why it is getting popular.

Cheers,
Velo Dog.

My apology to all if my above post response didn’t print.
I managed to forget that I was typing it under the Edit time restriction.
And it rightfully timed me out.

CBH Australia,

In brief, I was just curious why you would want a .260 Remington, since it duplicates the 6.5x55 that you already have.

Cheers,
Velo Dog.

Oh, in a round about way I decided I wanted a .260 rem for a target cartridge as I don’t want a 6.5creedmoor.

Now in the the space of a target round that is splitting hairs but I got sick of the hype and the way a new shooters face would light up when they mention it.

I looked at the limited range of factory HB .260 rem available. I could have got a discounted Tikka TAC-A1

I still have Peterson brass on back order.

I got a new old stock shop soiled Tikka 6.5x55. Tested it to be accurate in the light barrel and went away to the gunsmith and said let’s put a .260rem in this long action because I have a HRS Bifrost stock.

We discussed a few things and he said why not go 6.5x55 and load it to potential.
On the drive home interstate I thought it over ,and over.

Now because of the stupid rules in my state I would need to do a change of details on the chambering notified by a dealer. I gave in and said just do it in 6.5x55 on a Varmint barrel. Due to the Tikka action face they don’t support a heavy barrel.

I have not fired it with this barrel because I might sell it.

I had a Rem clone action built with a heavy barrel in 6br to get .243 performance with less powder available brass , and good for my purposes.

In brief, , just re read that. I plan to have a .260rem heavy switch barrel for my clone action built target rifle (Kellbly) That’s why I’m not using the 6.5x55.

Hoping I have many years ahead of me on the range along with all the hunting I can achieve

 

[Velo Dog]

I understand.

Being a fellow rifle enthusiast like yourself, we want what we want and that is that.
Various reasons drive our choices but at the end of the day, we are enthusiasts and sometimes we are eccentric.

Ammunition availability somewhat influences my choices of calibers.
Therefore, wildcat cartridges do not interest me in the slightest.

History, nostalgia and many years of proven track record are the major driving factors behind my wacky tastes in riflery.

I know I am eccentric and at times, it’s to the point of being quite odd, if not totally weird with my taste in rifles and related equipment.

Rant over.

Not knowing you, but you have never come across as eccentric.

I was intent on staying with standard offerings like the common ones on offer in most stores in Australia.

But, I took a detour

Thanks for that,

But most anyone who is around me for any length of time will tell you that I’m eccentric, if not simply an “odd duck”.
Even my dog is eccentric.

My next step of load development:
S365 , 43.2gn , ELD-X 143gn , OAL 78.75mm
S365, 43.4gn , ELD-X 143 gn , OAL 78.75mm
S365, 43.6gn , ELD-X 143gn , OAL 78.75mm

Will measure chamber length after this round ....
I need to get to at least at 2750f/s enabling me to work in the most productive range of velocity know for the M96 Carl Gustav 6.5x55 Swedish Mauser ...shooting out to 300 meters small groups is the aim...
This will be my longer range hunting /gong shooting rifle ....

 

[Wayne t]

been running a swede years was told by the old guys years back one of the best cartridges ever
I’ve had a sporterised 96 that I passed onto the wife as my first one never let me down
Ive been shooting a sig sauer ssg in it for ages and then just like busses two more come along at once that I couldn’t turn down
Zoli tiga and a merkel helix both in the 6.5/55 brand new in the boxes and the wood on the zoli is way nicer than the merkel that’s apparently a grade 4 wood

I'm assuming you're hunting high-ish country, 1000 meters or higher.

At 2650 - 2700 fps MV at that altitude, you're still above 2300 fps at 325 yards/300 meters.

sgt_zim, always nice to have your input and great informative replies ...I like this forum with all the knowledgeable members who always assist in developing loads and giving great information...
2300f/s at 300 meters will be great to ensure less meat damage and deep penetration for sure.
Looking at information from 6,5x55 shooters`s load data I am still safe when moving up to 2750 f/s with my 6.5x55 Swedish Mauser in the M96 version..

I love my Swede, but I typically like to be one power level over what’s necessary. To quote Untouchables (and I ain’t from Chicago, but I like the Chicago way)

You wanna know how to get Capone? They pull a knife, you pull a gun. He sends one of yours to the hospital, you send one of his to the morgue. *That's* the *Chicago* way! And that's how you get Capone. Now do you want to do that? Are you ready to do that? I'm offering you a deal. Do you want this deal?
