6-6.5x47 or 6br

[6.5 shooter]

Hi folks,

First time poster, I have been lurking for a while but havent posted til now.
Well im Garry from Northern Ireland and most of my shooting is vermin at range with a bit of steel plate aswell.
I shoot 223, 220 swift and I just recently built a 6-6.6x47 lap for something with a bit more reach.
Problem is I cant get it to shoot just aswell as my 6.5x47 tac rifle
Im thinking to myself I wonder should I have just built a straight 6br instead or can the 6br be matched or beaten accuracy wise by the 6-6.5 but I just havent found the holy grail load yet?

Has anyone had similar experience and went back to 6br after trying the 6-6.5x47 or has any one upgraded from the 6br to 6-6.5x47 and never looked back?

Interested in youre real world findings please?
I am shooting 105 gr bullets.

Garry

Yes, I,m on my 2nd 6-6.5x47 barrel now and like a few others I have found they can be tempermental. Sometimes, good, sometimes not. At the moment my 6-6.5x47 is going fairly well, but doing load developement to keep it perfectly tuned all the time would wear the barrel so I just except that I will use more of the X ring in verticle than I got with my Dasher.
Some people with more knowledge than myself put it down to the smaller primer being at the edge when it comes to igniting a long powder column WITH SLOWER POWDERS used in the 6mm version and the lighter faster pill not building up as much pressure before it starts down the barrel? Could this be why the 6.5 version has a better name than the 6mm?
I find mine works better in hot weather and never any good in winter, could be the powder I use?

Everyone seems to rave about 6BRs and Dashers for accuracy for a reason, and my Dasher in the prime of its life was just so consistantly tack holing accurate.
I have 2 more shoots till the end of the competition season and the barrel will then be chambered for either a Dasher or BR.
But then this is for high end competition only, even on a bad day, my 6-6.5x47 would be more than good enough for hunting.

I am using n160 powder in mine and it seems to be ok accuracy, groups floating +\- 1/4 inch with an es of just over 20 for ten shots.
Maybe im just being too fussy but I have got the rest of my rifles to shoot one small hole. Id rather have more accuracy and less velocity rather than more velocity and slightly less accuracy.
I know 1/4 moa is still good enough but If I thought i could get one hole from a 6br and lower extreme spread id pull the barrel and rechamber.

1/4 inch 10 shot groups? I would say that is accurate!

Isn't that one hole? What size groups are you looking for?

 

[6.5 shooter]

Hi Erik,

Its 1/4 moa 3 shot groups. 10 shots over the chrono came to 20 es.
I know this is good but I just want to find out if there is more achievable accuracy out of this calibre and is it worth the effort necking down brass etc over the 6br.
I have never owned a 6br so I have no baseline to judge.
What sort of accuracy and extreme spread are people achieving with their 6br and do you think the 6-6.5x47 is worth it over the standard 6br?
My groups are one large ragged hole.

Regards

Garry

My 6X47 shoots 2's all day with standard deviation in the single digits for 10 shots . At 3200fps with 105 JLKs , and RL17 I would'nt even fathom going back to my 6BR , or Dasher . They can't hold a candle to it . If you're having deviation problems I'd look at tuning that load again . Many of us don't spend enough time working up to a good load .

LCazador- What do you expect to see for barrel life with that load?

howdy guys..
wondering ... is there any advantage in 6-6.5x47 over a 6 dasher for score under 600yards...
i'm in for a new project soon an not sure about what barrel to order ...6mm or a 6.5 ?

6.5,

I know many guys that had the same results fom the 6 x 47L, The 6.5 x 47L does very well. The 6BR and 6BR IMP will out shoot anything at 600 yds, and do very well at 1000yds.

I think Don Nielson would disagree. ;D

My 6.5x47 shoots 130 vld bergers at 2800 fps in one single hole with an es of 3!
This is no fast load but boy does it group at range well!
Maybe im spoilt with this kind of accuracy and im expecting the same from the 6x47.
I just dont want to shoot a 130 grain bullet across the field and id rather a 6mm bullet do the job.
Im just being fussy, although im just wondering if a br case or variant would be more accurate.

Garry,

The 6BR and variant will be just as accurate. I would like to try the 6.5 x 47L. But the 6BR's are hard to beat.

Erik,

Don have done very well with his 6.5 x 47. But look at the record books. Ask Sam Hall about the 6BR and variants. I know there will be other rounds and shooter doing very well, but the 6BR and variants hold must of the records. The 6 Dasher took top 10 or so places at the 2011 IBS Nationals.

MarkS,
That's because the majority are shooting 6BR's or variants of it. Take the F-Class Nationals for example, most if not all of the top 10 had a 7mm. 5 years ago they would have had a 6.5-284, because most people shot 6.5-284's at the time.

Do you think that if Sam Hall had a 6.5x47 Lapua he would come in last after all the Dashers?... I didn't think so! ;D

Don't get me wrong, I know the 6BR's and variants are tack drivers, my point is they come in on top because most people are using them, that's all.

 

[MarkS]

Erik,

Sam would come in first if he was shooting a slingshot. Sam did have a 6.5 x 47L 2 years back per season. I guess it did not shoot as well as the 6 Dashers he is shooting now. Sam has tried them all, but still comes back to the 6BR and IMP. When 600 IBS started, guys were shooting everything. A lot of 30 cals from 1000yds BR. 6mm came to the top very fast. Joel Kendrick was kicking ass with a 6 x44, By the end of 2005 a few of us were shooting 6BRX's and 6BR, and winning matches and breaking records. The guys shooting 6BR and IMP are shooting them because they win Matches, not because everyone has one. All but one IBS 600 yds records were shot with 6BR and IMP.

Canuck. I am running the same components with my 6x47 (40gns powder). I played with seating depth and mine much prefered .015" jam, didnt go so well with jump. Might want to experiment with jamming even though the bullets are meant to be seating depth tolerant.

I built my 6x47L as a varmint rifle so with that in mind I shoot 75grn V-max`s driven by 39 grns of AR 2208 (Varget) velocity is 3750 fps with es in the single figures and .2 moa at 300m.My ladder test was .2 grain increments from 38-39 grn and all 10 shots went into.23 moa at 300m.When this chamber has its day it will be rechambered as a 6x47L

are dies ready made fore the 6.0x47 or do you have to have custom dies made ?

thanks
