6mm rem.why isn't it

[akajiggs]

I never hear of anyone shooting the ,lacking for a better word,obsolete 6mm rem.I am just an ignorant hillbilly trying to learn something here.
Is it just not as accurate as say the 6br,6xc or some of the others.
Could you put that cartridge in a quality barrel chambered by an excellent gunsmith with a custom action and a bench stock and be looking at a shooter.
Sorry for ignorance but I would like to know.Just hate to see a good cartridge die.Thank you.

It's way to much powder for the 6mm, maybe the heavy 6.5's but I think it still may be a little over bore.

Look up Richard Franklin, he LOVES the 6mm AI.....


Lots of people still shoot the 6mm.

 

[GerryM]

Its a great case Mine love,s 4895 and 85 gr sierras.

It is one of the FINEST 6mm cartridges ever created. It is especially good in it's A.I. (P.O. Ackley) version. It it undoubtedly one of the L-O-N-G-E-S-T range varmint cartridges in existence. With proper BIG GAME bullets it will hammer deer sized game well out beyond what you should be shooting them. It is EXTREMELY accurate and could easily be used in F-Open. However, you would be doing good to get 700 rounds (accurate rounds) out of it if used in that capacity! BUT if you did, WHOA it would be VERY hard to beat! I have never used it in that capacity, however, you should be able to shoot, with a 30" barrel, a comfortable 3300-3400 f.p.s. with 115 DTACs>> IN THE A.I. version..

Additionally, a little known "trick" if you will, is to use 7mm Mauser (7 x 57mm) brass and neck it down to 6mm, blow it out and gain an easy 1+ grains over a "standard" 6mm case blown out.. AND you will get better brass to boot.

I had 3 6mm Rems and one in the A.I. version>>>>phenomenal cartridge indeed!

I would love to have one! Even a 6mm AI. Having been a 243 win shooter all my life, I am always looking to the next size up, while still keeping the recoil monsters at bay. It is a caliber I seriously consider with my next 6mm coyote blaster that will have a very fast twist for the 6mm heavies.
I think the calibers that are popular here are with competition shooters that consider every single advantage that the details of a certain case brings to the bench. Barrel life being one of the big ones.
If a person doesn't compete, then it isn't as much of an issue. I have about 350 rounds down my douglas 1-12 barrel, always taking the time to let the barrel cool. I only hunt in the colder temps (40 degrees and less), so barrel heat isn't as much of an issue. I am addicted to bullet testing tho, and Im not sure why. I have several loads that shoot half MOA if I do my job, but I test away anyway.
Look how in recent years the 264 win mag has rebounded after spending decades in the doghouse. If i would get the chance to get a deal on one and put a muzzle break on it, wow! A 140 grain berger w/.612 bc and low recoil? That would be amazing!
If you would want to try something with it, try a different twist in a new barrel. Faster or slower. My douglas shoots the 70 TNT's great. The 88 burgers are right up there with it. (If they ever start making the 88's again that it is.)

370BC, if you ever do decide to get one for hunting, say for the Coyotes you mentioned, I would use RL-22. It is a bit dirty for long strings of shooting, as in competition, however, for hunting it is excellent. In my 6mm A.I. I used 107 SMK's and 105 A-Max's. With a 26" barrel, I was getting almost 3400f.p.s. but I was pushing it. I decided to cut it back to 95grs and started using the 95 Comb Tech Ballistic Silvertip. I was pushing it to 3475f.p.s. with excellent accuracy. It was a virtual BOMB on our "smallish" Texas "Hill Country" deer. On Coyotes it would rain total destruction on them W-A-Y out there!

Remington made two mistakes with the 6mm Remington.

First, it was named the 244 (NOT a mistake), but they gave it a slow,12" twist, cuz they saw it as a super varmint cartridge (which it is)... but the 243 came out with a faster (10") twist and advertised it as a varmint/deer cartridge, and the 243 took off.

So, Remington came out with a faster twist (9") which was good.

But the second mistake was big - they changed the name to 6mm Remington.
America was not ready for a metric named cartridge, and turned their backs on the 6mm.

Same thing happened with the 7mm Express - you couldn't give them away - Remington discontinued the 7mm Express for a few months, and then announced the 280 Remington (the exact same cartridge, same twist barrel, exact same everything), and it has been a huge success.

The 6mm Remington is still VERY popular for custom rifles, and even Winchester makes a special run of brass every few years (which is sold out before it made).

It's way to much powder for the 6mm, maybe the heavy 6.5's but I think it still may be a little over bore.

Pure Bull poopie... the 244/6mm Rem is 2 grains larger than the 243.

 

[snert]

It is a GREAT groundhog cartridge. Just finding brass is tough. HAve had several and loved every one of them. My last barrel held 1/2 or under to just under 2900 rounds. Then it finally went kerput...so had another barrel put on...they can do that, ya know.

I have had a .244..12 twist shilen on a rem 700 action for 25 years, a friend suggested one to me after his shooting one for 40 years or so. Everything from fox, prairie dogs to a antelope. The 85 gr Sierra hpbt
Is extremely accurate for me. A great overlooked cartridge, with a slower twist barrel it is extremely fast with a 60 gr bullet. I love that 6 mm/244 cartridge. Saw an antelope drop at 600 yds in Wyoming wit a 85 gr Sierra hpbt. Luck was with us that day. Too bad we don't see the popularity of that cartridge today.
Brass is a problem to find.

[nastynatesfish]

I use a 6mm Remington. Necked down to 224(22/6mm). I'm coming to like it a lot. I think it's a perfect case for the heavy 22 bullets
About 3700 with a 75 max and retumbo

 

[akajiggs]

ShootDots,what twist were you running in you 6mm to shoot the heavier bullets.Mine is a 9 twist and it will not shoot anything over 75 gr.I have not shot any of the vld bullets because of the mag length.
I would take it down and build another,but my wife bought it for me in 1981. Guess I will keep it like it is and shoot the 75gr hp in it.Thank you.

A 9" twist should shoot anything up to 105's. You have other issues.

 

[Shynloco]

Good Morning Guys,
Just saw this thread and not trying to hijack it. But since this is a learning moment and Cat has raised an issue that I've wondered about in the past AND oldwildhog mentioned it (that he can't shoot anything over 75gr bullets and Cat writes he has other issues); why is it that some rifles having a given barrel twist rate that is SUPPOSED to shoot bullets up to a certain gr weight, but won't go up to that level ((105's in this case) while the majority of barrels with the same twist rate WILL shoot up to that weight level?? Sorry for the long winded question guys but I've experienced what oldwildhog has (not in 6mm Rem) and always wondered why. Thx.

It's usually more the shape of a billet. The longer bullet contacts more surface. A bt bullet with a long nose will contact the same amount of rifling as a shorter flat base bullet.

 

[shortgrass]

I did't know that the 6mm Rem was obsolete! Might not be found in factory chamberings but I sure seem to cut alot of them, especially in A.I. If it's being called obsolete because of the lack of brass, I'd say there's a lot of cartrides that are "obsolete". Heck of a varmint/deer round in my part of the country.

Alex... good "hijack"

Anyone that says they know why, is... well, you know

Burger has a program on their website that is supposed to calculate bullet stability. Now, there are certain combinations of velocity, twist, bullet weight and bullet design... that just plain, God damn work every time.

Like a .224 bore, 14" twist, 52gr hollow point, at 3,100, but Berger's program says it at the edge of unstable. Huh???

A lot of what people claim to be stable or not stable, is either myth, or based on the old Greenhill formulas that were derived from empirical data (trial and error, for you guys in Rio Linda) gathered from blunt nosed, lead bullets... and then tweaked.

A few years back, someone promoted the idea that the BC of a bullet shot from a light weight barrel was much less than when shot from a heavy barrel... and people were dumb enough to believe it. Huh???

Why a barrel of a given twist will not stabilize bullets of a specific design, when another barrel will shoot small groups with the same bullet is one of those things that I doubt we will ever know.

It's usually more the shape of a billet. The longer bullet contacts more surface. A bt bullet with a long nose will contact the same amount of rifling as a shorter flat base bullet.

A longer bullet of the same weight contacts LESS barrel, not more. A boat tail of the same weight contacts LESS barrel than a flat based bullet.

The 244/6mm Remington obsolete???

Sure, just like the .220 Swift, and the.22 Hornet,

 

[MarkS]

oldwildhog,

The 6mm Rem is a great round. I have had 3 6mm AI. Your 9 tw should shoot Hornady 105gr, not the Berger's. Try the 87gr Vmax. Are you sure it is a 9 tw, not a 12 tw.
One thing about the 6mm Rem is the Rem brass it is not the best. Win did make it a few years ago, I don't know if they do now. That is one reason the 243 used more, better brass and factory ammo.
I have gone to the 6BR and 6BRX for my shooting. The 6BRX can run 243/6mm velocities., with less powder and much better accuracy.

[Ledd Slinger]

I have a 6mm Remington and absolutely love it. It's one of the most accurate rifles I own.

 

[Changeling]

Well, this has been a really interesting thread. ShootDots has fairly evaluated the round and brought to light the difference between the 243 and 6mm Rem in case capacities! I bet this started causing "Squeals" of "NO" from the 243 guys as they rushed to verify the statement, LOL.

I have used the "6mm AI" for a long time and found it to be one of the most accurate/effective 6mm rounds available in the high velocity realm of FAST and ACCURATE cartridge designs.
It's just one of those cartridges that works, pure and simple!! I don't think that anyone will ever know why exactly!

Caveats: Use Winchester brass, NOT Remington. I've always used Winchester!

For my next barrel I will be using Lapua (7 MM Mauser) necked down, set up as "No Turn".
