6BR or 6Dasher?

[South Paw Sammy]

Not sure if this is the right place to ask?
But here we go.
Wanting to get into the 600yrd and 1000yrd matches, This year (a few months ago) I got two rifles both 6x47L's (when your left handed you jump in with both feet)
Ive' been able to do some shooting at the house(out to 300yds) and both rifles seem to shoot pretty good for a rookie shooter anyway.
Everything I have been reading tells me that the 6x47L is a good round, but to be really Competitive at the 600yrd matches, the 6BR and the 6Dasher are the way to go?
It may sound strange a rookie wanting to be competitive? but when I do finally get a chance to go to a match I would like to have something that is in the ball park.
if I re-Barrel one or both rifles, What would you suggest? and what twist rate would you suggest?
And if I should post this somewhere else on the site please let me know?

Thanks
Sam.

If you are going to stay within 600, the BR is a great choice, easy to load, very accurate, decent barrel life.

For 1K, the Dasher works just fine. But you'll need to form brass from BR brass, until a commercial outlet becomes available. If you are considering F class, there are better cartridges for 1K, but the Dasher is doable with good wind calling.

For sling, in both mid and LR prone, I use a Dasher. Although I like shooting my Palma rifle, lower recoil, the accuracy of the BR, ease of loading, long brass life, the Dasher will spoil you. Best decision I made on a rifle build.

For just starting out go with the 6mm br, it's a lot easier for someone just starting out no fireforming just load and shoot and do a lot of reading on this forum.

How do your 6x47's shoot?

 

[South Paw Sammy]

Hey y'all thanks for the information
I don't know how to up load pics on here but on 10-3 and 10-4
I was shooting my Panda not sure of the barrel manufacturer? But it's a 8twist and I 30" long with the break. The best that day was a .134 and the worst was a .930
I shot five five shot groups the first day and five five shot groups the second day. If just did the math right the average of all ten groups comes out to .621?
Sorry I'm trying to do the math and type all of this on a cell phone.
The other rifle a Bat action with the same barrel length and twist, I haven't shot that much waiting on a new set of rings and base for that one.
Thanks again for the help.

I'm not sure you need more than you have now. Go try what you have and see how you do before you 2nd guess. Much of any success is being decisive. It's not that scary to compete, there's something for everybody at a match. You won't be the first guy to try it for the first time, trust me on this.

South Paw Sammy.... listen to Mike. He won't steer you wrong.

Would think you have the 6mm's covered. Maybe go a 6.5x47L or straight 284

+1 Your 6x47L should be very competitive at both 600 and 1K...doubt it's worth the effort for you to change to a Dasher...maybe when you get better.

The 6BR does not have enough juice to work well at 1K. For 1,000, it depends on whether you shoot at windy places or not. The 6x47L will work well for you at 1K....until it gets windy. Then, no 6mm cartridge is going to do well. A 6.5x47L with an 8-twist barrel and 140 hybrids will do much better in the wind at 1K. A 9-twist 284 WIN with 180 hybrids is the gold standard.

600 or less 6 br 600 or more Dasher. Larry

I shoot a 6mm BR at 600 yard in F-Class. It's OK, but I'm certainly not convinced it's the best choice. It is accurate, not too expensive to reload, low recoil, and components are readily available. Plus there is plenty of load data and factory ammo is available too. Barrel life is reasonable as well.

But the 6x47 Lapua has some appeal, at least to me. The larger case can give the same 6mm bullets I shoot a LOT of additional velocity. In other words, same bullet cost, same BC, same availability, but less time-of-flight. What's not to like? Well, for one thing, you have to make your own brass. But going from 6.5x47 to 6x47 is apparently as an easy "wildcat" cartridge to make as any. It's really not a big deal, from what I'm told; just a matter of annealing the neck and running the brass through a sizing die. But there is very little load data and no factory ammo either. But people who shoot the 6x47 Lapua claim it's easy to tune, very accurate, and while barrel life isn't as good as 6mm BR, it isn't all that bad either.

As a 6mm BR shooter, I find myself dreaming about moving up to the 6x47 Lapua. I know this; if I owned a pair of 6x47 Lapua rifles I would be hard pressed to follow the advice to change to 6mm BR until confirmed for myself that I couldn't make them shoot or until the disadvantages of using a "wildcat" cartridge proved to be too big a PITA.

Just because lots of folks shoot 6mm BR at 600 yards and just because the 6mm BR is a good choice (especially as a starting cartridge for 600 yard shooting) doesn't mean that is the best choice, and it certainly is hard to say it's worth changing from the 6x47 Lapua you already own.

For sure, I would say stick with what you have for a while until you prove to yourself that a change is warranted, if that day ever comes.

In 1000 yard BR the Dasher dominates over the 6 BR. Hardly any 6 BR, 6x47, 6.5x47or 7mm anything shows up. The 2 that show are 6 Dasher and 300 WSM. BR and F-class are 2 different games. In BR both group and score count and group takes Precedence. A quick look at all the records or big matches whether IBS, NBRSA or Williamsport show almost all the records were broke by 6 Dasher or 300 WSM. Almost all the aggregates are also won by them.

If you are going to shoot NRA F-Class you will have to take the muzzle brake off. If this what you are wanting to shoot, test without the brake ans see if it is still as accurate.

The X-ring in F-Class is 1/2 MOA and this is the accuracy you should work toward at distance.

Hey ya'll thanks for the information and encouragement, I am taking all of this in.
the main thing is to just get out there and shoot and get some matches under my belt and have fun.
I'll take any advice i can get.
gotta be short today just had some issues come up here at work.

Thanks again and Ya'll have a Merry Christmas if I dont get to talk to yall between now and then.

Sam.

 

[jawjaboy]

Sam, I shot my first official match with a borrowed rifle I had only first shot 2 days before. You're way ahead of the game with your own rifles.

 

[suberjc]

Stick with the 6X47 L
Try Berger 105 Hunting VLDs.
Start off running them about 3100 (H4350)
Go to touching the lands and work in slowly.

I know I know. Just try em.

South Paw Sammy,

No round can run with 6BR and 6BR Imp's in 600 yds.Benchrest. For 1000yds the IMP's will do better. I run a 6 BRX and done very well at 600yds. shooting 3 IBS records, with a 0.749" LG Group in 2007. I tried to get more speed with a 6XC, but accuracy was not there, as a lot my friend, trying the 6X47L found out also.
Some of the 6x47L will shoot very well, some don't. Take what you have to a match and see how they shoot. The 6BRX and 6Dasher run best with a 105 gr or 108 gr. Berger at 2975f/s
Try the speed in your 6 X 47.

I don't think it's strange at all. If one didn't feel this way I'm not sure they would ever do very well. Shoot shoot and shoot if your going to shoot BR I would go ahead and go with the Dasher
