6br versus 6x47 lupua

Haven't had the 6x47 but a friend of mine had one for a while and he told me that he had more of a difficult time getting it fine tuned compared to his 6BR.

He said the 6BR was just so much more easy to tune and more forgiving.

Actually, he even went on to say that he had an easier time tuning the 6.5x47 Lapua compared to the 6x47 version.

Take that info for what it's worth.

Just personal preference but I would choose the 6mm BR for that distance. Or go the Dasher route.
 
Maybe I was lucky, my 6x47 is as accurate as my 6br or 6bra.
I might have gotten a hummer of a barrel.
And it wasn't hard to tune.
This was the seating depth test, dated 2019
@100yds. It shot one hole groups quite often with 103g
I use to say, I could close my eyes and it would shoot small.
I pulled it after 800 rounds and still have it. Need to put it back on and shoot it some more.

Two of my favorite cases, 6BR and the 6.5x47 necked down to 6. I’ve had several 6BR and variants and they are easy to tune and accurate. I have a 6x47 built by ODCR that has shot everything I feed it into itty bitty groups. Between those two cartridges I really don’t think there’s a wrong choice, the 6x47 feeds better but with the new mags the 6BR does just fine. I’ve used 105 hybrids in both with excellent results.
 
6BR is just an awesome cartridge. Ive been shooting it for many many years along with 6.5x47L. Everything I stick in my 6BR's, powder, bullet, it just hammers.

Ive been shooting 6.5x47L even longer and its a straight hammer over numerous different barrels over the years. I went 6.5x47L for the brass before 6.5cm existing and stayed with it while many went to 6.5cm..

These days, you can get excellent brass for both so you dont see many people adopting x47L anymore.

I never got into the faster 6's like 6x47L, 6cm, etc for barrel life.


This was 3 five shot groups in a row @ 100yd testing some new DOD 106 A-Tips in my 6BR with my 30.2gr 105 Hybrid load.. No load development or tuning. Just swapped bullets... This is why I love my 6BR's..

I agree that the 6X47 may be a little harder to tune but I'm on my 4th barrel and have a 6BR And have 3 6 Dashers and the X47 will shoot with every one of them. I'm really not getting all out of my X47 that it offers but it shoots insanely accurate at 2950fps and it easy on components at that velocity. Now as far as the easy button the 6BR is like a little 308 it's the easy button IMO. Some people may can get high velocity out of their BR's but I run mine pretty mild with 105s. If I had to pick one cartridge for 600yds it would be a 6Dasher for me! I know some people don't do this but I shoot a short barreled dasher at 600 23-1/2" works good for me! Just My 02
 
Afternoon
Is there an accuracy difference between these cartridges if they are both using 105 Berger hybrids at 600 yards?
Thx for the help

Hi. Why do you ask? Because there are different answers to the question. Are you building your first gun and trying to pick a cartridge? You already have a 6 BR and want a little more oomph? I agree with 6 BRA. A skilled tuner/loader/shooter could get equal accuracy from either case. I currently run a 6x47 with a 109HT in the low 3100s at 1k yards with what I would call Dasher accuracy (routinely less than 3/8" at 200 yd). I want to run the higher BC bullet fast at 1k to help in the wind and I am prepared to accept the resulting barrel life.

Let us know your goals? Competing? Shooting for fun? On a budget where barrel life is more of a concern?

When in doubt build a Dasher. But don't be fooled: all of the 6mms fry barrel throats, especially with 2x base powders.
 
I presently shoot F class and after taking a couple months off, I’ve just got back into it. The reason I was asking is I shot a 6 x 47 that I had a barrel for on my panda and I had trouble in the high windy. Conditions controlling it. My friend was shooting a 6.5 x 47 Lapua and did much better got me by a few points but I think that 6.5 bucked the wind better Another person that was shooting with us. He had a 6BR and he shot as good as the 6.5 x 47, so my question was if the BR is capable of out shooting the 6 x 47 but the design of the cartridge ?

Yup. I frequently get beat by a small margin by 6.5x47s when the wind is tricky even though my 6x47 is much faster and flatter. We all know that within a caliber its better to run a heavier BC bullet slower. The higher BC usually beats out a bit of extra speed. Same is true from 6mm to 6.5mm. The higher BC of the 6.5 is likely to edge out the faster 6mm bullet in the wind. I think this is the main consideration, not the group size at 100 yd. If you want to win, go up in caliber.

You seem to be loyal to 6mm like me for reasons I can't explain or justify. So I run a 109HT fast to get the most out of 6mm in the wind and that takes a bigger case and 30" barrel. 6BR is probably a bit more accurate, but 100 yd groups are just 100 yd groups. The downrange ballistics far outweigh a slight accuracy difference at 100 yd IMO.

Hi. Me again. You guys following this thread seem reasonable to talk with - I don't bother with guys slinging hype and zingers and gotchas. The reason I replied at all was I've only run the 6x47L for a year. I needed to because I was working on a batch of brass for the wildcat I normally shoot. I did not previously consider the 6x47L a Benchrest cartridge - didn't think it had the accuracy. Dono why. Just assumed it was better for PRS and other roles.

It has far outweighed my expectations and I'm considering sticking with it. Thus chatting with you guys. It just goes against my (obviously incorrect) beliefs that 6BR, BRA, BRX, Dasher are the accurate 6mms.

You asked about accuracy. I put the attached together to summarize my year with 6x47L if you want to take a look. Bill

Thanks for the replies everyone it’s been suggested that maybe going to a Dasher might be a good choice for 6 mm could someone give me the 101 for building a Dasher anything peculiar to it I know you have to fire form brass and a friend just told me the other day that Alpha sells already made brass and so does Peterson And I see lapua is gonna come online maybe at the end of the year is there a special reamer involved with any of this thanks for the help

With the 6GT on the market now too, I would sure take a look at it also against the Dasher.

If you are looking to have an advantage with wind @1000 use a cartridge that will get you good fps with the 115gr class bullets. The 6xc has worked well for me over the years and it worked very well for D. Tubby also with many championships. Using a cut rifled barrel such as a Kreiger one can usually get 2500+ rds before accuracy drops off.
