6 mm Remington

[CJ6]

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?

Precision Reloading had 6.5 284 Lapua brass last night. $163.19 per 100 but they also had a 12% off code for orders over $100.

Now there is a viable option, thanks CJ6!

 

[wildcatter]

Absolutely, a 6x47 is very easy to neck, and a very efficient 6mm cartridge. I just sold one and was very impressed with it. I'll probably end up with another someday. But I'll always have a 6mm AI, unless I have a 257 Bob AI, my favorite cartridge from this case!

 

[AckleymanII]

The kiss'en cousin to the 6x47 lapua is of course the 6 XC, and I have found it a very, very easy case to tune with 105-108g bullets in 8T. The 6 Remington with today's powders would be a Magnum.

 

[wildcatter]

With a 1-8 twist barrel the xc, 6x47 are a better choice unless you want to load the 6mm AI down to their level for optimum accuracy. I gave up on trying to push the 105 and heavier bullets past a little over 3070fps. I have taken them to nearly 3400 fps, but all at the expense of less accuracy!

I have that barrel cut down to 6BR and have a 1-10 twist barrel ordered where I can push up to 95 gainers around 3500 fps, without creating to many rpm and over stressing the bullets to the point of compromising accuracy.

Expensive lesson, but now I know why those cartridges all deliver match winning accuracy, with the big bullets, and the bigger cartridges dont!

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.

Every batch of Lapua 223, 222, and 308 that I’ve used was less uniform than Norma and RWS. Enough to matter? Probably not. The Lapua is also harder than both, and Norma is so soft that I would say it is somewhat disadvantageous. I still really like Norma, but you can’t load it hot, at least for the first 2-3 firings, and sometimes you need to load hot to get your desired results.

I recently prepped and sorted 150 Winchester 6mm Remington cases and the results suggested that 1000 Winchester cases would not yield a single group of 100 that was as uniform as 100 Lapua, Norma or RWS cases right out of the box.

I recently prepped 200 Lapua 8x57 cases for use in a 6mm Rem and 6.5x257AI. Those 200 cases were hands down the best brass I’ve ever seen. I didn’t think RWS could be beaten. Maybe I got lucky but those 200 cases are so darn close to perfect that I’m not sure I didn’t make them worse by working on them.

If necking down, check your neck clearance, and turn if necessary. Also anneal your necks you won’t get many reloads before they split.

 

[AckleymanII]

Wild catter, you may have a typo on that 3500 fps on the 6 BR with the 95s.

Wish I could Lay in a supply of 8x57 Lapua brass.

 

[CJ6]

If your going to neck brass down why not get RWS 6.5x57 brass ? Much easier.

 

[Ackman]

My goal was to shoot 70BT's @ 4100, to equal the 240 Gibbs and work with a particular scope/reticle that was designed for those ballistics. AckleymanII has done it with the 6mmAI. Also a friend made several varmint videos and did spectacular things to rockchucks with the 6AI and a 75Vmax at estimated 37-3800. (Years ago some clips were pirated onto youtube and touted as shooting taliban out of rocks, but that's another story). My 6AI is a 26"Bartlein 12tw, 0 freebore. Been fooling with others and spent only a little time with this one, just looksee groups at 50yds to get on paper and some idea of what it will do. Nosler 70bt's shot into - literally - one very slightly elongated 6mm hole with a couple charge weights. The 75's a little larger. A pleasant surprise. If this is any indication of longer range potential it will be rockchuck poison next season. Winchester brass, not easy to find anymore. And Frontier .257 turned with about 60% cut necked to 6mm. Any performance difference is yet to be determined, haven't shot enough of both to tell. But I do like necking down and turning to size.

No, I didn't say I was running the 6BR at 3500, I said I made the 1-8 twist barrel a 6BR because you can't push the 105's to 108's to 3400 in the 6mm Rem or Ai, any faster than a 6x47 or BRX, etc class of cartridges at those rpms without loosing accuracy. I ordered the 1-10 barrel to get 3400 to 3500 fps, but I mentioned with a 95 grain bullet, because you can't stabilize those heavy bullets with a 1-10 twist.

This should have been obvious to me when for years those bullets are capable of setting and holding records, when used in the smaller cases that are only capable of pushing them around 3050 to 3100 fps. without comprimising absolute accuracy.

Sorry for the confusion!

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.

Last few years I have been buying older Rem and Win brass, probably from the 70s? I think it is pretty high quality. It is expensive but I have a pretty good supply of brass in a few different calibers that are no longer popular.

I see alot of post about Rem 6mm brass. When I could not find it, went 7mm brass. The 6mm was designed off the 7mm.. Anneal it, Lube it run thru full length sizer, if needing trimming, then fire form. Fire-forming will smooth out any crinkles in shoulder, ck trim lgth. and go for it. lol.
Been shooting Rem 6mm for alot of years. Started with 788, finally shot out the barrel. It had old twist 1-11.
Best load for it that I found was Rem. brass-WLRM-40.2grs.-W760. Push old SMK-70 over 3k, won alot of match`s with it out to 400yds. lol
Now I shoot Rem. made 03A3 action, Monte Carlo Stock, Timney Trigger, Shaw 1-8 26in. heavy barrel. With 36x Gold Ring, 1/8 dot. Use the load of 40.2 grs. WLRM W760 pushing 107SMKHP-107 gr. at 2865 fps. I moly coat all my match bullets Could push it faster but at my age lol at 407 yds. cutting same hole so reckon I`ll leave it alone.
P.S. The darn thing will only shoot Rem. Brass. Here is the proof.

I have owned multiple 6mm Remington rifles for varmint and deer but only one left today. To use that chambering in 600/1,000 yard competition might be fine if you can get a properly tuned load for the rifle. Unless you have or built it in a heavier barrel contour, properly scoping for target, it probably would not be competitive. You really need something that can do .2MOA or LESS. That does not mean you would not have fun. Then there's another issue.

That issue would be the short barrel life. From new the typical 6 BRA/Dasher's get 1,400 to maybe 2,000 rds of competitive barrel life. Some less ... few more if you want to be competitive. A 6mm Remington will even be less barrel life than a 243 and that's too little. The case, by design, just holds too much powder for that kind of repetitive shooting.

It makes a fine low round count varmint cartridge but you can burn it out on Prarie Dogs.

I took my first Mule deer and antelope with a Remington 788 in 6MM Rem. I also shot many coyotes and hundreds of jackrabbits with it. I shot that barrel out and bought another 788 in the same cartridge. I still have dies and 80 or so cases. My last 6mm rem was on a Mauser 98 action and I also shot that Douglas barrel out. It is now a 270. Great cartridge though I doubt I will ever build another.

 

[Red-ass]

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.

Hey, 17VLD, try the Shaw S.S. 26in. 1-8 twist. Ya be pleased as peach if`n ya do. Ck my post 2nd page. Red-ass

 

[Albany Mountain]

I would think the 6 Remington would be great at 1000 but factory twist offerings do not have 8 twist barrels. Remember the 244 Remington had 12 twist barrels and the 6 Remington had a faster twist for larger bullets. But not 8 twist that is required for the heavier bullets that would be good at a thousand

I'm embarrassed to say that when I dusted off my Ruger #1 about 3 weeks ago (after ignoring it for the last 20 years) i found 15 of 120 pcs of Remington brass had split necks. In that most of them had been fired, I annealed what seemed to be salvageable. I also purchased 50 Prvi Partizan cases in 6.5 X 57 Mauser to add to my inventory. In an attempt to reduce the working of the brass I purchased a Redding "S" sizing die (the last one Midway had).
In the meantime I had been playing with the Corbin bullet swaging system and made up a few 100 grain flat base 9 tangent radius bullets using some rather questionable jackets (I won't identify the source but they are not J4's). Checking Berger's twist analyzer, it looked like my 1:10 would work.
I loaded up a few of the bullets ahead of a reasonable load of VV-N160 and a Winchester primer and promptly fired a 3/8" 3 shot group which in pretty impressive for a #1.

I have that barrel cut down to 6BR and have a 1-10 twist barrel ordered where I can push up to 95 gainers around 3500 fps, without creating to many rpm and over stressing the bullets to the point of compromising accuracy.

Expensive lesson, but now I know why those cartridges all deliver match winning accuracy, with the big bullets, and the bigger cartridges

can you clarify for me, a 6BR 1-10 twist can push 95 grain bullets at 3500 FPS? If so whT length barrel?

 

[JeffSummers]

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

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.
