Which is "best". 6 x 47, 6XC, 6 Creedmore, 6SLR??

[Frankr]

Soon after Mr Tubb designed it, I wanted to build a 6XC for shooting prairie dogs but the (then) necessary case crunching to form brass scared me off. Ended up doing a 6-250AI instead. Now that factory brass exists, the 6XC is a total no-brainer.

And like you kind of, when I first seen Norma Brass available for the 6XC I thought stupid just another case bla bla bla.
boy was I wrong..hey it happens.

 

[Sheldon N]

so your statement there is just not valid at all. sorry I hate being the bad guy.

Easy there, I never said that you couldn't shoot H4831 or a 115 DTAC in the 6xC. It's obvious that you can, Tubb is the one selling both of them.

Just pointing out that as you go up in capacity from 6x47 -> 6XC -> 6 Creed -> 6 SLR it gets easier to run both heavier bullets and slower powders. And you can do it with less pressure which is beneficial for brass life and barrel life.

I also said that brass quality was the most important decision factor, which favors the 6X47 and 6XC over 6 Creed and 6 SLR.

I don't personally think there's "magic" in any of the case shapes, maybe a hint of efficiency and accuracy advantage to the shorter/squatter 6x47 and 6XC cases... but that's just cause they're closer to the Dasher.

All this stuff boils down to trade-off decisions from multiple factors. You can't just declare one is "best" and say screw the others.

We are going to have to do that in November..lol.......

Haha!

I shoot PRS, so our finale is in January. Last years winner ran a 6x47 Lapua, this year the number one shooter is running 6XC. We'll see who comes out on top!

I have a pac of them Norma's too Factory Norma loaded with a molly coated Berger 105 VLD Target. Quite Expensive, not for shooting, Just for looken at. well I shot a few of them,not a hand load .Looks like the price came down only $112.00 for 50 rounds when I got them I thought they were like 145.00View attachment 990969 View attachment 990970 View attachment 990970 View attachment 990970

FJIM,

That is a good looking case and loaded round. Slightly off topic, but does anybody have any velocity readings from an 18" 6XC with any bullet from 87gr to 105gr. Just trying to get some idea as I am in the process of building a 6XC. Thanks for any info.

The 6XC came about by trying to improve on the 243 Win faults. the XC is better feeding with VLD type bullets, It's is more inherently accurate has better barrel life case's stretch less. there maybe more but just what I can think of.
In most cases the 6XC can duplicate or exceed 243 win Velocity. In a properly set up 243 I would think the 7.0gr difference would help some in the velocity but it give's up too much in everything else to justify the slight speed difference. The 6XC is just kind of a perfect case for launching the VLD type bullets. I thought about a 6 SLR, I had a reamer for a .243 30deg IMP and dies ready to chamber a new barrel and after shooting a 6XC for about a year I decided to sell the reamer and dies and just chamber it in 6XC because it is so easy to load,So accurate. It is just RIGHT is the only words that I can explain. I had a buddy just put a 1-8 243 together. I tried and tried to talk him into a 6XC but some just don't understand it. It shoots well. But it is not a 6XC by any means.

This is my professional opinion yours may differ or vary slightly.

You need to talk with John Whidden who won a lot of 1000 yds and records with a simple 243!

what will any of those do that a straight 243 Win wont,,,I have a 28 inch 8 twist Krieger chambered in 243 Win with the throat lengthened to seat the 105 VLDH at 2.825 COAL and have a .020 jump ,,,

with H4350 it runs those 105 VLDH bullets at 3200+ and shoots very well,,it`s to easy for most people I guess,,

I believe the benefits of these cartridges over the 243 would be barrel life. I do not have personal experience shooting a 243 but the barrel life of a 6xc is 2000+ rds.

 

[Hengehold]

Has any of the new 6mm cartridges defined themselves as the best of the bunch? They all seem to be similar in case volume, size and output velocity. Is it just the parent case that everybody wants to use that determines the choice? Thanks

Any reason why the 6dasher is not among the list of cartridges? My understanding is that the dasher would be in the same velocity class (105gr @ 3000-3100) as the rest of them.

I have had several 6xc 1000 yd rifles but no experience with the dasher. I think my next barrel will be a dasher now that commercial brass is available and I will never have to trim brass. Seems to me that a dasher would have most of the benefits that were listed for the other cartridges such as quality commercial brass, accuracy potential, ect.

[tbeasley]

The new Norma 6 dasher brass isn't getting the velocity like some expected.

What exactly is the OP question? Are you asking a best of all cartridge for BR gun or for a repeater? Because depending on what the use is, we can eliminate and criticize from there.

 

[Grimstod]

I would think a Dasher would be a bad choice for a PRS rifle. The sharper shoulder does not feed as nicely and that short neck will allow runmout if your banging your ammo around like the guys do in PRS.

Not true, I believe four guys in the national top 20 are running a Dasher right now. Last years second place finisher ran a Dasher. Low recoil, inherently accurate, small efficient cartridge running very close velocity to the super popular 6x47L and 6 Creedmoor, it's a perfect PRS round.

It's on the upswing in popularity for PRS, especially with new CRF actions like the Bighorn TL-3 and Mausingfield that feed and eject the Dasher well.

I'm having one built and based on the internet chatter over at Snipers Hide there are many, many others who are building Dashers to run in PRS.

 

[Frankr]

I built a 6 Dasher BR rifle(built by one of the best) and my experience with it was not as blessed as others. I got good help with it from guy's on this forum and it was accurate but it was finicky almost reminded me of a 6ppc how it can be in a hole one minute and then just shotgun. So I was disappointed in my Dasher. 26" 1-8 twist it was way out on the edge at 3,050 with a 105 more like 2,950's was more accurate.So finicky is how I would describe it. frustrating.

The 6XC just works mine shoots well from 2,950's to 3,150 with a Berger 115 with at least 5 different powders I can think of. Now it is not a benchrest rifle it is a tactical/Hunting hybrid is how I would describe it. 10.5lbs scoped.
now it will keep 5 shots in that group and if I play with wind flags and really work at it I could maybe get a little better
I know the numbers don't look great but it's holding about 2" of vertical at 700 yards.I have not spent enough time at 1K targets to tell you how it groups there but I just ring some steel plates. I think it is super accurate with enough velocity,enough case capacity to be versatile . I can't wait to get some of the new 115 DTAC's.

Both of mine completely different rifles will shoot in the mid .300's at 200 Yards. I feel that is quite accurate.That is a one inch dot so you can quarter it up.

I think the shoulder angle the same as your beloved 6.5x47. Also a top prs shooter designed a AI type magazine adapter to accommodate the dasher.

 

[Sheldon N]

40 degree vs 30 degree, but still feeds well. There are two companies producing AICS magazine adapters for the 6BR/BRX/Dasher cases, Patriot Valley Arms and Primal Rights.

Holy crap, I thought a dasher was blown forward 30 deg, I ought to research before I post, lol.

The BRX is the 30 degree version of the dasher. It might be more popular if it had a cooler name.

 

[Milo 2.0]

Yes the BRX was the reamer print I had looked at before my outburst of knowledge. I can't stand abbreviations myself.

 

[benchrest]

based off of brass options i would go 6x47 or 6xc

i went with lapua, the 6x47l with the small primer pockets holds up very well. some claim 20 firings on a piece of brass.....dont think i will take mine that far but it can probably make it.

how is the brass life of the 6xc? how many firings can you get on a piece of brass?

all of these cases can hit the 105gr bullets velocity sweet spot. so you're basically just picking a brass you want to use.

 

[XTR]

I am forever amazed at the devotion people have to Lapua brass. Yes, it looks better, yes it's packaged better, but I have yet to be able to shoot well enough to see it better than WW. In my rifles, with me shooting I've never been able to tell the difference on the target.

Now granted I'll don't shoot BR and have obviously lower expectations (I'm not looking for .1s or .0s) but my testing at 300 yards in 308 I I get consistent verticals in the .2's.

As for "have to make it" with the 6SLR, sure you do have to run it in a die before you load it, but whether it's WW or Lapua or LC223 I never load new brass out of the box. Any new brass I load goes over a mandrell and gets chamfered before it's loaded so using a Whidden die instead of a mandrell the first time the only extra step for me in loading a 6SLR is putting a little Imperial on the neck.


I don't have any groups to show but my 25" 6SLR running "crappy thin brass" shooting with a Steiner scope that has a fat aiming point routinely prints groups under .5 groups at 300 yards running 105s at 3100 or so with a load that I'm pretty sure may never wear the brass out, and there are a fair number of HM long range HP shooters that are running the 6SLR these days. I think there were at least 4 of them on the line at Oak Ridge in a recent regional.

Where would the so-called 6mm 'Long Dasher' fall in this mix?
