6 mm Remington

[kochie]

Anyone shoot the 6 mm Remington caliber in target competition 600 yds or 1000 yd competition?

 

[Kurz]

I used to shoot one of the many variations in competitions at 1,000 yards. It was the 6mm Crusader which has a 32 degree shoulder and slight body improvement, about 61.3 grains of case capacity. One of my favorite cases to shoot.

Now though the trend towards smaller cases and less capacity is in full swing.

I started out using the 6mm Super LR case which is fine at 1,000 yards also. But now I switched to the 6mmGT case and the 105 VLD bullets since I have so many.

I will always have a 6mm Rem. and I keep lots of cases on hand just in case.

Enjoy!

6mms are great and there are a lot of different chamberings for that caliber. The only problem I see with the 6mm Remington is the lack of quality brass. And yes, I had 2 - 6mm Remingtons. Now I have one 6mm Remington and one 6XC. 6 mm is my favorite caliber.

The only problem I see with the 6mm Remington is the lack of quality brass.

These days, finding any brass which suits your cartridge choices is favorable. This is especially true with those cartridges which do not enjoy all the hoopla of newer cartridges. The 6mm Remington does not now enjoy any of the accolades showered on the 6PPC or the 6BR or any of the other 1/2 dozen 6mm wunderkind cartridges. So it languishes on the sidelines because of being ignored in favor of more dollars, faster from the manufacturing of those cases with more notoriety and higher sales figures. So it goes. Many cartridges can claim the same.

If you can't find 6mm Remington brass you just need to join the ranks of those of us who rely on converting other cases. Currently I've found .257 Roberts +P, 6.5x57 Mauser and 7x57 Mauser without having to use the resources that I have stocked up on in the original case.

I do understand that most reloaders glorify Lapua brass as being the pinnacle of quality and when they can't find the cases they want by that manufacturer, they believe that they are taking a step down. That may well be. But...

I've been using Remington and Winchester brass in 6mm Remington for a few decades without any drawbacks. Do I get 15 reloads from each piece? Nope. But I rely on recipes utilizing newer, modern powders which burn cooler and at lower pressures.

Sometimes we just have to dig a little deeper to find the brass we can use.

The 6mm Rem sure is a great cartridge my Ackley version was built back in the 70s by Charlie Durham and accounted for many varmints throughout its lifetime.
I have since put a new Lilja on it but in a moment of questionable thought process I decided on making it a 6-284.Most likely because of the ease of obtaining Lapua for yet another Varmint caliber that I thought would be the coolest one yet.Dont get me wrong I love the 284 case and all it’s offspring but I often wish I had another 6mm Rem Ackley or standard again.Wish I was smart enough to have purchased a 1V or a 700 BDL VS in 6mm back when.Will keep my eyes peeled for one, at the very least I will barrel one of my 700 actions in 6mmRem eventually.

Kochie -

Howdy !

I designed my " DEEP 6 " wildcat so that the chamber could be cut by running a
6mm Remington reamer in " short ", for a nominal .466" base diam.

I utilize 7 X 64 Brenneke as the parent case. 7 X 64 is .308 bolt face compatible, rimless.
Norma 7 X 64 brass is superb !

Since my wildcat's cases are formed using the lower portion of the 7 X 64 brass, DEEP 6 cases have thicker upper case' side walls and shoulders than most factory cases do.
So, they are very robust, and last a long time.

DEEP 6 case capacity is in the 6XC - 6 Creedmoor zone.

In theory..... a 6mm Remington barrel could have the chamber section shortened for a .466" base diam, and some threads added; to arrive @ a DEEP 6 rifle. The donor barrel would need to have enough material thickness in the chamber area to allow such an exercise to take place. And... enough barrel life should still be present, so that such a project even makes sense.

Thanks again very interesting

Great cartridge made even better by taking it to the Ackley Improved version. You make brass from any case used for the different cartridges based off the 7x57 Mauser case.

But if you want as good as it gets, mine are made necking down the 8x57 Mauser case from Lapua. I use many flavors of Lapua brass, 6.5x47, 6br, 220 Russian, 30/06, etc. But that 8x57 brass is as perfect and tough as any I have used to date from Lapua or anyone else!

I will say for competition, with a 1-8 twist for long range and heavy 6mm bullets you need to keep em small for 600 or 1000 yards group competition, it's over bore!! I built one and found them big 105's to 115's don't like more rims than 3000 to 3060 fps puts on them.

I could drive them 3250 and better, but accuracy came around the same speed I get with 20 grains less powder at those speeds with cases around the 6br case.

So I reserve this 6mm Remington AI for the slightly slower 1-10 twist barrels, and 80 to 95 grain bullets over 3300 fps for Long Range Varmint duty. Allowing those bullets to give their better terminal performance for better quicker kills out past 600 yards. Something I've found the smaller BR case strugles with from its anemic speeds out that far.

Just the results I've learned from.

Make no mistake, the supiority of Lapua cases should be obvious. Nothing wins more, and those using it aren't using it because the want to spend more. They also don't use it because it isn't better, but want more challenge!

It is what it is, the brass every single other brand is judged by.

I don't say this to argue, I state it because those that don't know should at least have the facts to make their decisions. In the Varmint field it may not matter, but when it has to be the best, it matters.

 

[Zero333]

If you're willing to make 6mm Rem. brass from Lapua 8 x 57 IS ( neck down with bushing die in a few steps down to 6mm and then neck turn ) then it might be worth shooting the 6mm Rem.
Otherwise R.P. brass is shit,.. flash-holes most of the time not even centered and punched like shit with lots of burrs protruding in the inside of the case.

Same here made some with Lapua 8x57 then fireformed to 6 Ackley really nice brass

 

[AckleymanII]

I have shot Many 6 Remington and several of the 6 AI. Every chuck shooter should own a 6 AI in his life time.
The last two 6 Ackley's had 26" barrel.

One 10 twist Douglas shot the 70g Nosler at 4000
One 14 Twist Shilen shot the 70's at 4100. 80g Sierra single shot pistol bullet at 3800
Both barrels shot similar loads, but the 10 twist had pressure about 1.0g sooner for what ever reason.
Chambers had zero freebore

In standard 6 Remington customs, I ran 60g Sierra at 4000 fps, shot into bug holes, and 80g Sierra's at 3600.

I was running Rem and Winchester brass with winchester taking the pressure of the 70's at 4100 much better.

Rock Chucks looked like they had been shot out of a circus Cannon with the 80g Sierra.

We all like fine brass, but Winchester and Remington will serve you fine for varmint hunting, coyote, and deer hunting. R#26 with 105-115s would be awesome in Lapua brass, but a friend here is killing deer with the 95g nosler ballistic tip at 3550 out of the AI where he says they never take a step....what ever that means.

The 6 AI, 6/284, and 257 Weatherby(zero freebore) are the flattest shooting varmint rifles I ever put together).

I gave up on the Remington brass, 2 or 3 loadings and primer pockets were very loose, with some so loose you could press a primer in with a finger.

Now that was in a 257 Roberts, AI. THAT Roberts was shooting 85 grain Balistic tips faster than a buddy could push them out of his 257 Weatherby.

Sorry but after using both, I could never call the Remington brass anything but a poor choice in any AI case, where most are building one to push hard. Anemic loads I suppose any brass will work.

I also found more consistent accuracy and lower Extreme Spreads using the Lapua 8x57 cases. Just my personal experience.

 

[Fast14riot]

My dad finally shot out his 6rem barrel on his 1000 yard f-open gun. Shot 105s out of it, did pretty good. He's building a 6br now (different gun) and were looking at rebarreling the 6rem to 260 or 260AI because having two 6mm guns only 200fps difference shooting the same bullet is a bit redundant.

 

[DocDoc]

You will like a 260AI. Some see it as the "Goldilocks" case capacity for the 6.5mm.

 

[AckleymanII]

Wild catter, Brass was plentiful, I fire formed on hair, decapped by hand, tossed the lose pockets. We were hunting coyotes, lost a lot of brass while hunting as were looking for multiple coyotes to come in, had NO interest in trying to catch brass. Agreed, the rem was softer for the AI purpose, winchester much tougher.

If Lapua 6/284 brass were available, that would be the best choice today, but It may have gone the way of the DoDo bird.

Wildcatter, where would I buy 8x57 Lapua brass?

I'm sure you know that any 284 brass will never work for a replacement case for any cartridge using a 7x57 case, standard or Ackley Improved.

I would try a want to buy, trust me there are other gunowners out there hoarding it, some that don't even have a need for it.

Same with a 222 Lapua brass, I just bout a few hundred new. But a willing gun owner was who made it happen. I would guess at the big matches where many sell components. Much like the IBS Nationals, a good place to find components competitors in those competitions are in need of, from powder to primers and cases, usually at better prices than the scalpers demand.

GL if you make the attempt!

 

[AckleymanII]

Of course, I know, I was mentioning the 6/284 as an alternative, more available than the Lapua 8x57 brass, which probably came from Canada?

Hot rods are falling out of favor now for the medium size cases with high bc bullets, many more shooters are not reloaders, never will be....way too much thinking required.
