Is the 6mm BR my next gun?

[BuffaloBill]

I’m relatively new to the precision game but have been shooting all my life and reloading since 1979 or 80. As others have said, getting tiny groups out of a 6BR or variant seems to come easily (6BRA in my case). It’s inspired me to try 22BRA for my next build.

 

[Benchrest Braxton]

anything br, bra, dasher will be stupid accurate

my 8 twist carbon proof 16.5" 22 dasher pistol.

3 different charges 0.5 grain apart at 100 yards, 2 shot groups.

going to be a groundhogs worst nightmare this coming year

 

[Infrequent Shooter]

I have been shooting highpower rifle (XTC and Long Range) competitions for 25 years. 2-3 yrs ago I put a 6BR barrel on one of my guns and it was one of those experiences that made me think, “where has this been all my life?”

It is by far my favorite cartridge to shoot for competition/paper targets.

Low recoil and incredibly easy to get it to shoot well. Bullets are relatively inexpensive compared to larger caliber bullets. Lots of capability in a low cost per use cartridge.

Ha, A lot of us are wired to do something the hard way. I sure am. Guilty as charged.

 

[Belly Benchrester]

Shoots small and easy to load for! My wife shoots ragged hole groups with mine at 200 yards too. 28.5-29.0 n140 and a 105-108 stacks them up

 

[ELR LVR]

I'm the odd man out,
I prefer a 22 BR in all aspects --- all the way
I have a 6 BR, but it's boring to me, no skill required lol

If you want a boringly accurate cartridge, a 6 BR is one of them

I have a 6BR Norma.it shoots 105s and 108s very well, but I've not had any luck at all with any bullets 100gn and under.

I have found this to be true for my 6BR barrels (all 1-8" tw.). They shoot certain 105's and 107's extremely well, though when trying bullets in the 80-90 grain range - the performance has been very mediocre, despite varied component changes/tuning, etc. I retired one of the barrels to varmint shooting and was dismayed it absolutely would not shoot the 87 V-Max, which so many find to shoot well in their rifles. Fortunately, I dropped down to a 75 V-Max (stoked with Rel. 15) and it hammered!

Forum Boss: it may have to do with bullet diameter. My 8-twist 6BR PacNor shot 103 -105s consistently 1/4-MOA, 90s were also accurate, and the 80s often drilled one ragged hole for 3 shots. I could pretty much shoot any match bullets sub-0.3 MOA that I could get into the lands a few thousandths.

Two nice looking rigs you have there.

How far were they jumping?

Save time and $$$, just do a Dasher first time.

 

[ghostrider272]

Have an X Caliber carbon 6 BR Norma running right now. Really like the round and setup I have. When that barrel is done, I have a Schneider 6 BR Rem barrel waiting for installation. Glad I found this round!

I think when Lapua finally hits the scene with their Dasher Brass, everything else will become a second thought.

I think it is weird that factory dasher brass is made with a short neck. Why not give it the same NK length as a standard 6BR?

 

[charlie b]

Probably because it would then become a different cartridge, ie, it would not fit in std Dasher chambers. Dasher is just a blown out BR case.

I am a little surprised no one has made a 'Dasher' with a longer neck. But, there is the 6GT.

87 Vmax is a crap shoot--some love em--more than a few can't get them to shine. I gave up on them --life is too short to play with bullets that won't shoot

What about the "Norma Dasher" with a longer neck?

“Oh no – not another wildcat!” I hear you rant. OK, I know, wildcats are one of those creatures you either love or hate. Regular readers of Target Shooter will know that I am a ‘cat lover through and through and the Dasher is certainly one of the most successful wildcats ever. Need convincing? Take…

Thread 'New Production Norma 6mm Dasher Brass'

Dec 3, 2018

I received 200 of the new production Norma 6mm Dasher brass today (from Graf's), and decided to provide some info for the group regarding it.



I made some rough measurements as a comparison:

Cartridge-- LOA-- NECK LENGTH
Lapua 6mmBR-- 1.5555-- .3100
Lapua 6 Dasher Hydroformed-- 1.5375-- .2050
Lapua 6 Dasher Fireformed-- 1.5320-- .2250
Norma 6mm Dasher-- 1.5960-- .2900

The Norma shoulder is at the same length as the...

[BULLET 05]

I love my 6 BR! I purchased my Br and really started the reloading habit after I got this gun. Savage action, custom barrel, rifle basix trigger, custom laminated stock, Leupold 8x25x50.

I believe that. It is not very often I can't get a particular bullet to shoot with powder changes and tuning techniques- but that bullet challenged me. I'm going to measure the diameters of those bullets just to see the differences.

 

[BULLET 05]

I have had trouble with consistency with the 87 V Max. The last few boxes I have tried have not shot as well as earlier boxes from 7 years ago. I will say that I really think the 87 V Max is an awesome bullet for varmints. They really do what they were designed to do.

Norma did up to last year. It is .050 longer. I have enough Brass till death do us part...........

How far were they jumping?

I tried the range from .040" off to as close as I could get to lands with enough bullet still in the neck to provide good support. The 75 V-Max was jumping pretty good and put them into about .200" +/-. I had really wanted the 87 V-Max due to the improved ballistics. The 87's were more like 1/2+ MOA. While the 75 V-Max is super accurate, it doesn't provide much superiority (ballistically) over other calibers I shoot at ground squirrels, like .22 Nosler and the 63 ELD-VT, which recoil even less, use less powder, etc.
