I have a walnut/blue Ruger MkII chambered in 300RSAUM and like it a lot. Always wished I had grabbed a 7SAUM in a Model 7 before they were gone.

Now I have a hankering for a 6.5 in a short action, and am tempted to fall for a 260 in Model 7 stainless or perhaps the 6.5 Creedmore, but keep hoping that the 6.5SAUM will be introduced as a factory chambering in something like a M700 Mountain or Ti.

Why don't you talk to Remington about this, though they will probably not give you any information?

Have you considered a 6.5x284? Factory ammunition is--or was--available from Norma.

Does the big Green R even chamber for the 6.5 CM ?

I have spoken with Remington, with no response.

Don't hold your breath waiting for a 6.5 RSAUM Mtn. Cool idea, but
It wants an Intermediate length magazine to accomodate those 6.5 VLDs properly. Same issues as the .260 really.

You might be able to do something with the Custom Shop for a few $$$
Remington is known for twisting the 6.5s too slow.

The 6.5-284 is a long action chambering, that has developed a reputation for short barrel life, mostly due to throat erosion. This is exacerbated by the .284s short neck.

If you don't mind wildcatting, I'd turn it into a 6.5 SS(Sherman Shortmag). Or a 7 SS, for that matter.

6.5-284 certainly a possible. Irritating how Remington doesn't support their cartridges... i don't even think they load ammo for the 300RSAUM any more... all ten loads available at Midway are Nosler... for Nosler to be offering ten loads, someone has to be using the 300RSAUM. grin.

I love my Model Seven 7 SAUM. I contacted Remington about their brass availability. They said that they are a loaded ammo company first and foremost. And that they would release brass as they gain a surplus. They then claimed that they still offered factory ammo for that cartridge. I asked them where I could find some of it, cause I haven't been able to find it. They said that they had no way of knowing where it was. Lol

Some time ago I read that pretty much all of the brass and primers we get for reloading from the ammo makers is what's left after they fill their orders. I'm sure there are exceptions, but that's the general rule. They'd rather sell high-profit ammo than brass. It's always risky to jump on the new cartridge bandwagon, especially when the round isn't based on a common case type.

I would doubt seriously they would ever consider 6.5 saum as a production chambering. Not saying it would never happen but highly unlikely.

If you want a short action 6.5 I would pursue a 260 rem, 6.5 creedmoor or the like. I am afraid you would grow moss waiting on a 6.5 saum. And I think think a 6.5 saum would be a great cartridge offering but just don't see it.

I don't believe the SAUM series has been a great success for Remington; I doubt they'll ever be a factory 6.5 SAUM.

Build your own 6.5SAUM on a 3" action such as the Win70 or Ruger77.

Easy neck-down/false shoulder from 7SAUM.

Bingo - 3" mag is the key with the 6.5s, maybe not even enough for the most VLD 140's

Sure is tempting for Medium to Long range hunting.

I don't know about factory, but GA precision appears to have a good grasp of the cartridge,plus hornady is making the brass. There are a handful of gun smiths reaming barrels to the 6.5 saum frequently. Everybody I know with a 6.5 SAUM will not part with it,I had a semi custom 6.5 creedmoor built a few years ago and I remember people saying a 6.5 whaaat...Now, creedmoor is common to the guys holding up gun counters. My last full custom was a 300 saum, so I think a 6.5 saum could catch on with enough of us "loonies".

I was somewhat dismayed to recently see MuleDeer selling off his "highly accurate" 700 take-off barrel in 7 SAUM,
here on the free classifieds. Went quick.

Tragic lack of commitment to the chambering.

Perhaps he converted his stash of brass to 6.5s for a feature article ?

Wonder what the mag length is on a Tikka T3 .270WSM..
Then there is the Kimber 8400 Shortmag action..

To the best of my knowledge, all Tikkas are a long action. Why the fascination with the short action? I have never understood that.. Several 6.5's that will do whatever, but for the most part are a long action cartridge. If you want magazine restrictions then get a short action. If you want bullet selection light to heavy, then you need the longer action. 6.5's for the most part is a rather long bullet not friendly to short cases and magazine lengths.

Yes T3's have long actions..
But my question is will their .270WSM DM handle a COAL of 3.00" or close to it..
If they do, then for me that would be the way to go for a fairly lwt. hunting rifle..
Cheaper than a Kimber, lighter than a M70 or R77..

I wouldn't bet my next pay check on it

Don't know on the length, but a few guys have done a 6.5 SAUM on a T3. Seems to work well...

The AW mags let you seat out to 2.96 I believe. No problem with the Templar short action that GAP uses, which is pretty much a Defiance Rebel action.

I haven't had any issues with mag length in my Model Seven. I load to 2.80" with great accuracy. However, I don't care to shoot bullets that need to be close to the lands.

Winchester should make a 6.5 WSM

Given the propensity for modern cartridge creations to not make the grade, and if you want reliable access to brass and factory ammo, I gotta believe the smart money is on 6.5 Swede, 260 Rem, and 6.5 Creedmore (in that order).

I bought a Tikka WSM magazine this past Sunday, the max internal length is 2.905" to the best of my ability to measure it. Of course you'd want to subtract a few thousandths from the cartridge OAL to give the nose and base some clearance.

Didn't they have a 6.5mm short action magnum a few decades ago?

Thanks Jim..
The wheels are a turning..
Need to find some 6.5 SAUM brass dies and reamer first and someone to import it to Canada..

If Buck Rodgers had a deer rifle.....

My son likes his pretty decent. It's the 350 RM version though

Dang nice buck there! Rifle looks better without the Buck Rodgers rib. Bet the 350 hammered that buck.

I would bet it will be a factory round.

Think about it. The rifle companies have to come out with new chamberings, even if there is no reason to.

6.5's are growing in popularity.

Its a logical step.

I would order them Creedmoor, 260, Swede.

If it's picked up by a factory, I hope it's Hornady!
They'll give it full support and develop ammo that works.

Winchester will let it fade in three years.

Remington will advertise it and let it die in six months.

I'd thought the .30 Rem AR was a possibility, glad I waited six months...

Since Hornady already makes the brass, it wouldn't be a stretch to see them offer factory ammo with the 143 ELDX

Despite the fact that the original has everything wrong with it (belt, magazine too short), mine in the 673 version has been busy this year......
