Advice for first 6br

[rookie7]

Hello all,

I've never shot or owned a 6br, but I'd like to try one.

Is there a difference in the 6br Remington and 6br Norma? Hogdgon lists the 6br Remington in their reloading data center.

I have a Remington model 600 that I would like to rebarrel to 6br.

Right now it has an aftermarket 20" .243 barrel on it, so it's not factory original. I got the rifle second hand many years ago.

I have a little over 400 Hornady 105 BTHP match bullets, so I'd use those first.

I'd like to keep it simple - no neck turning or anything special.

I have plenty of powder and primers.

This won't be a bench gun. It will be a fun rifle to take to the range to try and shoot small groups out to 300, and I may take it for whitetails and coyote.

I am thinking a light or medium palma (or something similar) 24" barrel.

I don't know which twist: 7" or 8" ?

Thank you in advance for your help and experience.

There are a bevy of great bullets for target between 103 and 109 grains. Those probably need 7.5 or 7 twist in a straight 6BR.

For varmint hunting, the 90-100grain class of bullets is excellent. These are the same bullets used by most 243 Win loads. I think an 8 twist will work here.

No less than a .272 neck. Lapua and Peterson have been loading up to .270 for me using virgin brass.

Really your gunsmith should have some influence on these details. I would focus on determining which bullets will be most valuable options for you. Freebore and twist will follow.

If you go to the home page of this site, you will find calibers listed on the left hand side. Click on the 6BR and you will get some really good information.

Thought there are said to be MINOR case dimension differences between the 6mm Remington BR and the 6mmBR Norma, but the main difference is that you need a faster twist and more free bore in order to use the heavier, longer projectiles. I have shot older 6mmBR (not Norma) in both of my 6mmBR Norma chambers.

My Remington Custom Shop 6mmBR Norma (Built at Dakota Arms after the move) has a 1:8 twist barrel. The custom shop bought a reamer to my specifications in order to chamber it. They still can supply the older 6mm Remington BR also. Won a Score match at one of Bob White's Bench Rest Clinics with it. Technically it even makes it into Factory Class at Club Shoots.

My Bench Rest rifle that I use for 300 yard shooting is also a 1:8 twist. But I have a tighter neck and need to slightly neck turn brass for it while my Remington 40X from the custom shop has a no turn neck.

And as pointed out, you can buy Lapua Brass and Lapua loaded ammo for this caliber.

I was considering ordering a barrel from NSS and doing a remage setup.

Both of my 6BRs have Krieger Barrels.

An 8 twist Remage will work fine with the bullets you have on hand . My 8 twist Remage shoots 105s down to 75s and shoots them well.

Blue-print the action

Jewel trigger / 2 to 6 ounces

Oversize/tapered recoil lug

Hart, Lilja or Shilen Select Match barrel - 23" length

A good, comfortable and properly pillar and glass bedded stock

6mm Remington Bench Rest / freebore cut to match your specific bullets / match prepped brass but no turn case neck

Tell your gunsmith to set the headspace to match YOUR brass.

When all is said and done and with the right loads, accuracy in the 2's on a good day should be very common for a non bench rest rifle as you wanted a rifle for - "it will be a fun rifle to take to the range to try and shoot small groups out to 300, and I may take it for whitetails and coyote"

I have built hundreds of rifles like this, and the accuracy potential has always far exceeded everyone's expectations, and usually turns out to be their go-to rifle for everything!

Lots of good advice already but I’d recommend better Bullets than the hornady 105. When I got my first 6br I used those and the groups were decent at short range but when you get out to more distance the groups just aren’t there. If you go to a higher quality bullet you’ll save a lot of frustration. Think Sierra 107, Berger 105 vld or hybrid or Berger 108 or lapua scenars

You didn't mention what kind of powder you had but if you have any RL-15, that is another go to powder. rkittine gave some good advise regarding home page & clicking on 6br. A wealth of info there.

I have had good results with the Sierra 107 Tipped Projectiles as well as the Berger 105 Hybrids and both the 90 and 105 Lapua Scenar Ls. Berger 105 VLDS have not been as good for either or my 6BRs.

First a 8 twist will work for you and the 107, 105 to 90g range.
The 107's are easy to shoot and finding a load for.
I used 95g Sierra's and could push them faster than the heavier bullets, using IMR4166
Had a .273 no turn chamber. The med. palma is a good compromise in a 24 inch will
be good for what you want.
The Sierra match bullets might not be the best for hunting. Not a lot of expansion with match bullets.
It's a fun and accurate round. It will do many things.

 

[rkittine]

Good point about target projectiles for hunting. I only target shoot, but I guess I would damage less of the meat if shooting Woodchucks!

 

[Danley]

Since your rifle has been rebarreled, there’s a chance that the action threads have been opened up (if the action was trued it’s a possibility). If that’s the case, a Remage setup isn’t going to work because they all come with standard threads (to my knowledge anyway).

I think you are picking a winner in the 6BR I would do the Norma chamber if you don't have a barrel lined up I can do a remage barrel for you about a 2 week turnaround.

My Custom Rem 700 6BR .271 neck .120 free bore with 1 - 8 Tw. Krieger 26 " barrel shoots the 95 gr. Target Berger and the 105 gr. Hyb. Target Berger very well. Varget with CCI BR-4 primers in new unfired Lapua brass was my initial load. Mine is the Norma version.

 

[std7mag]

From my understanding, the difference between 6br, & 6br Norma has a lot to do with the differences between SAAMI & CIP.

Much like with the 6.5-284, & 6.5-284 Norma.

With CIP if you change pressures, throat, freebore, etc. Then you must rename the cartridge.
The cartridge itself may not be changed, but if the chamber itself is changed in any way, the name changes.

 

[HTSmith]

You want the Norma/Lapua version. An 8 twist works fine with most bullets up to 108Gr. There are a few like the new Berger 109 that would take a faster twist. For your use I would recommend Berger 105 VLD Hunting. They'll work for varmints, deer, and targets out to 1000 yards. They are picky about seating depth, but once you find it they will shoot. Just my $.02 It will be a fun ride.

DON"T DO IT. All it does is start the opening of the rabbit hole.
