6mm Rem coal w/ 100 gr Partitions

[CjC73]

I'm looking at putting together a 6mm Rem and don't plan or desire to shoot the super heavies (105s or 107s). Just a good deer hunting bullet such as the 95gr or 100 gr partitions.

I'd like to build it on a short action and was wondering if would work. What's the COAL with a 100gr partition or interlock?

I'm not totally sold on the short but have one in mind, otherwise I can build it off a Tikka action.

I've read about it being done but it significantly reduces the case capacity.

Do you know if factory ammo is built for short action? Looking at the 100 gr factory ammo and it's listed at 3100fps muzzle velocity. I'm good with that. I don't need to squeeze powder in the whole case.

Yes. The Remington 700 in 6mm is a short action. They even made the Model 7 in 6mm. Not ideal, but not a huge handicap for conventional flat base bullets like the Partition

My 6MM Remington 700 BDL is not a short action. I bought it new as a 6MM and rebarreled it about 20 years later. The case is .314" longer than the 308.

Here are the cartridge and chamber drawings for the 6mm Remington SAAMI specifications:




Please note that the Minimum and Maximum COAL are specific to the short action magazine.

While you may have an exception, you have exactly that, an exception and not the rule. The factory ammunition produced since the release of the cartridge has always been a maximum of 2.825" OAL for the short action magazines.

I built my 6mm Ackley on a savage shirt action. Certain 90 &95 grain bullets like the Sierra TGK or SMK are nowhere close to the lands do to mag length restrictions. I suggest a long action if possible.

 

[AckleymanII]

I have shot many 6Rems in Ruger, Rem, and mauser. The mauser with it's long action was the best of all. I would suggest that you use a Remington long action and forgo the Tikka, which is an odd duck if you ever like to switch out barrels, stocks, triggers, etc.

Remington 700 short actions are a Pain in the butt with the 6 Remington, and that is an understatement.

My hunting partner and I shot the 95g Nosler partitions for years on big Nebraska corn fed white tails, later on, I used them on Cow elk, with no issues around 3100 fps using IMR 4831 with Rem 9 1/2. We attained better accuracy with the 95g than the 100 in various guns and barrels. Today, I would be using the R#26 with a cci 250 and would be all over 3300 fps in a 25" barrel, make the freebore around .030-.040 where the bullet should sit perfectly at the shoulder neck junction with the 95g. 85g Barnes TSX has also proved very effective with a heavy charge of R#19 and a Fed 215 primer where the speed/accuracy is unbelievable.

If you are absolutely stuck on a Rem short action, then consider having your gunsmith open up the mag well .120 for a Wyatt's mag box, that extra length will be cherished, 243 Winchester shooters could benefit from this also.

yep I would go long if possible. I have some 100 partitions, they are LONG. I will measure one if you want me to. The 85 sie and 87 berger are much shorter and their boat tails would help you in a short action. marc

What was your COAL with the 95g bullets?

 

[AckleymanII]

It will vary from gun to gun from Ruger, Remington, and Parker Hale mauser. I will work up a load with the bullet seated about .020 off the lands IF POSSIBLE!

Rem short action is A POS deal on a 6mm Remington cartridge. If you have tikka action on hand, that is your best option.

Plan for success in the future, not just when the barrel is new. You want to be able to chase the lands as the rifle is shot, hence the longer action is needed and preferably with a shorter freebore reamer that cuts the barrel.....WIN/WIN situation

If you are hard set on a Remington Short action, then consider the 6x47 Lapua which will give you great lattitude in OAL and mag box length.

I'll measure the action when I get back from holiday. I remember over 30 years ago (yea really) setting it side by side with a 308 I was selling and noticing that the action was longer than the 308.

I do remember that the gun dealer said he had a real deal for me and the rifle was in packaging when I looked at it. I believe it was $350, I can tell you that it pushs a 75 grain VMAX at 3,900 FPS, averages 1 1/16" at 300 yards, on dozens of occasions it has printed 5 shots in a dime at 300 yards.

Now if it happens to be a custom rife then I did get a deal.

All this made me look into standard (there none) action lengths. According to the link itseems it varies by manufacturer and Remington has 2 different short actions.

Short Action vs. Long Action

Do you need to replace the stock on your Browning A-Bolt or Remington 700? Are you confused whether your rifle is short or long action? Don’t worry, you’re not alone. Many centerfire rifle owners face this dilemma when ordering parts for the f

'(there none)'

That's because there are two ways that actions get categorized:

- Distance between action screws which can be and is a variable.

- Internal length of the magazine.

Remington uses two action lengths based on the action screw distance and overall action length. Originally, it was the XP-100 short (short) action, now Model Seven, and the M700 short action even though the magazine lengths were basically the same. We shot everything based on the .308 Win. cartridge length in both actions without modifications.

You need to measure the magazine box length to determine SA or LA. Long actions can have a modified magazine box where a spacer is added to the back of the magazine box to allow for a short follower and spring to be used for SA cartridges.

 

[CjC73]

Sort of why I want a Tikka action, can do both on same action. Great actions and nice triggers to start and even better with a $10 trigger spring and super easy to swap if needed.

I'm just looking at the 95/100gr partitions/interlocks for deer hunting. And lighter bullets to plink.

Now, just to find one, rifle or action.

My hunting partner and I shot the 95g Nosler partitions for years on big Nebraska corn fed white tails, later on, I used them on Cow elk, with no issues around 3100 fps using IMR 4831 with Rem 9 1/2.

Was this a short or long action 6mm?

 

[Orr89rocz]

I have a 700 adl in 6mm. Its a short action. Coal with factory federal 100gr partitions is 2.795-2.800 as the lead tips vary. rem mag box is small, appears 2.8 is about it.

fwiw i have a savage 11 rebarreled in 257 roberts that i can load to 2.97 magazine, depending on bullet but the short freebore limits oal with the longer heavies. Probably a better short action for a 6mm rem

There are two interesting aspects of this for me, 1 I may have gotten a buy on a custom rifle. 2 the 6MM Remington is certainly a maximum sized cartridge for a short action. The COAL of 2.825 pushes the limit as does the 57MM case.

As AckleyMan said, if using Remington 700, go with a long action. The problems being discussed here go back to the Rem 722's in 244, 257 Roberts, 6.5x55, and others based on the old Mauser length cartridges. The 722's and SA 700's are not long enough for these cartridges IMO. This is even more noticeable in a factory rifle that has a longish throat. You will not be able to come as close as you want to the rifling for accuracy, and have the handloaded rounds fit in the magazine. So at best you have a single shot rifle. That is why some went to a large ring Mauser for these chamberings. If you have Ken Waters' book he talked about a 3" 257 Roberts. In his instance he used an Enfield action. I have notes about the 722 magazine measuring 2.84" in length. With this limitation, I estimate handloads have to be in the range of 2.810" - 2.825" long. The Rem 722 in 244 has 1:12 twist, and even with appropriate, light bullets (60-75gr), the magazine length limitation caused me headaches. I'm certainly not suggesting a Mauser or Enfield action. These are just examples of remedies to this issue found in years past.

Best of luck, Peter.

"I'm just looking at the 95/100gr partitions/interlocks for deer hunting. And lighter bullets to plink."

Finding the action is one issue, finding a reamer with short freebore is another challenge. Standard freebore, you can barely touch the lands with a 70g Nosler ballistic tip.

Today, reamers are ground with the 105g long vld's in mind with 8Twist barrels, which means you are screwed on 55-80g bullets, an 85-87 would be minimum acceptable.

I would advise you to go to the gunsmithing section on this site and ask for gunsmiths that have reamers in 6 Rem with short freebore. I would suggest a 9T barrel for the bullets you want to shoot.
