Lots of info on the 6 dasher. Good barrel life. Great brass life.
6x47 has amazing brass life
6 creedmoor has a good following. With the new lapua brass things could get interesting with this caliber.

I was just thinking this very same thing. I have a R700 action and a 7.5 twist 6mm barrel sitting around.
6Dasher sounded good until I read it might need to have a bushing for the firing pin, special mag conversions and some magical reamer used depending on if I plan to use Norma 6dasher brass or fireform it out of Lapua. My head got so foggy I decided to circle back to this topic when I was more relaxed. Not bashing it, just a lot of info for me all at once.
Seeing as you asked I'll sit back and let the more knowledgeable guys offer up advice.

They're all very nice. If you subscribe to the theory of modern case design and inherent accuracy that rules out the .243. Just like the .260 though, it just flat works. When lapua comes out with the creedmoor brass, any potential gap will narrow further. I lean towards lapua brass generally, but so far my XC has been very nice.
This topic has been beat to death, and there will never be a definitive answer.

Bushed firing pin costs $100 and is helpful for achieving maximum performance from the case, but not necessary

I just went through this exercise. Fired the first 50 Dasher rounds yesterday. Had this build not been for my daughter, it would have been a 243win.
I get the whole 35° shoulder, long neck, etc. That said, your can load 243 down to Dasher velocity (my hunting load is 33gr Varget with a 95NBT) or pack it full of H1000, RL26 or N165 and push a 105 over 3300. Lapua brass. Large rifle primer. Not to mention, current NRA world champion's chambering.
Love my 6BRs. Probably my favorite rifles for fun. Dasher is coming along but a 243Win is one bad mofo in stock form or as an SLR.

I've been running the 6slr for a few years now as my go coyote round. Im impressed with velocity, how easy it is to load for and how scary accurate it is.
If I do a 6mm, it would either be the 6slr again, or the 6 comp match. Both are very similar and both give good velocity to barrel life.

Like my 6x47 Lapua, most accurate gun I own. Thought about other chamberings for simpler brass prep, no necking down, etc.
Might do 6 Creedmoor next time with Lapua brass coming out. Gonna see how much life I get out of the 6x47 barrel first and see if it lasts long enough to satisfy my desire for the caliber and its performance.

6 creedmoor.
You really aren't getting any magical barrel life out of any other 6 offering, all depends on how hot you load it and and what powder you use. Even then its not going to get you anything significant.
6creed hornady brass is nice, im up to 5 reloadings and my primer pockets are still fine and its cheap to replace. Lapua has brass in the pipeline for it, a company called alpha is coming out with brass for it in the very near future which is supposed to be very good, and its the only offering right now that has affordable match ammunition (hornady). There is no fire forming for cases like other offerings and you don't need to bush your bolt for small primers.
You already have enough offered for the 6creed right now to make it a favorable option over the rest but give it another year or 2 and Id be willing to bet it gets close to the popularity as 6.5creedmoor. Probably won't be quite as popular due to barrel life but if you are set on a 6mm offering its hard to beat a 6creed at this point.

I like the sounds of the 6x47 and 6mm creed but the 6xc has a strong fan base and there has to be a good reason why. Let me see if I have this right.
6xc is a 22-250 case necked up to .243/6mm and fire formed to a 30 degree shoulder? Allowing it to push a 105 bullet between 2950-3050 on the high side?
6x47 is a straight neck down 6.5x47. So long neck, probably allowing the 105 to run around 3050-3150?
And the 6mm creed is a necked down 6.5 creed with decent brass availability and able to run the 105's at 3050-3150 as well?

I have two 6 creed builds at 24" barrels and both push 105 hybrids at 3150fps and I definitely can bump that higher before i get any pressure signs. Youll see a lot of people stop before 3200 due to match fps limits but it is capable of higher.

6mm Remington? Yes, if you want to shoot the heavy bullets at max velocity, it's there. And if you want light bullets going slow, then barrel life will be longer. Same loaded round OAL as .243, and for the really long-range loads, go ahead and put your favorite bullet close to the lands, and if it's not mag-length, just single load. You'll single-load anyway for long range.

I like simplicity when it comes to cartridge choices. So that leaves the 243 and 6mm CM now that Hornady has factory ammo for it. Barrel life will be about the same. Not enough to say one is a barrel burner and one is a barrel saver. I dont like fireforming or having to do anything exotic to brass to make it work for a wildcat. That takes the fun out of shooting and makes it feel more like a job.

I first chose a 6x47 Lapua for the sake of simplicity. Very good choice it's extremely accurate and 3050-3150 is easily achieved with N160, H4350, IMR4451, etc.
I then started reading about and talking to users of the 6 Comp Match (243 w/31° shoulder) and David Tubb released the new 115 Dtac (.620 G1 BC). I am making the switch to the Comp Match. If these accurate barrel life numbers are correct, 3000-5000+ using H1000, the change is worth it. Seems like it works like the 6.5 SAUM, lower pressure H1000 loads pushing heavy for caliber bullets in cruise control, if that's what's going on, I have to try it.

I chose 6 Dasher because all the cool kids are doing it.
Slightly less recoil, better barrel life, uses less powder, benchrest level accuracy and easy to tune. 1000 yard benchrest competition is dominated by the Dasher. Tradeoffs are fireforming and that I give up a click or two of wind to the faster 6mm's in tough conditions.

Why not just do a .243AI, and enjoy even more case capacity, use Lapua brass, & run the same slow burn powder for long case & barrel life?
Seems like the .243AI hardly gets any love with the 'precision' crowd & I'm not sure why? Only thing I can think of is maybe only being able to fit 9rds in a 10rd mag, due to those blown out shoulders?
My necked down .22-243AI feeds fine from AICS mags, so I can't see there being a feeding issue?
The latest rage 6 Dasher has a 40 ° shoulder, same as the .243AI...

The reason I don't run a 243AI is cause you can't run AW mags. Deal breaker for me.
I have a 6x47 and just spun up a 6SLR for myself. I don't have a lot of time with the SLR the thought behind it though was cheap brass that I could leave at a match. The SLR is preforming great so far with 115 DTACs so I'm excited to try it at a match. That being said I have zero complaints about my 6x47

I have a 6 dasher and a 6x47. Not sure I prefer one over the other. Like the little extra speed, no fire forming, and the no fuss mag feeding with the x47. The dasher is supposed to get better barrel life, but I have a friend that lost accuracy in fewer rounds than I have on my current 6x47 barrel. It's possible his was a fluke. Both have excellent brass life (lapua in both).
In my hands they shoot similarly in terms of accuracy and recoil. A better shooter will likely notice a difference, but both are great for me.

Seriously though, I think the Lapua small rifle primer 6.5 Creed brass will last longer than the large rifle primer Lapua 243 brass will because of the extra brass in the heel and then there's the .059 flash hole.
Next would be the shorter length of the case giving a bit more latitude for seating 115 DTACS or the new 110 SMK's in AI mags. I'm leaning towards going to those bullets right now when I run out of the Berger 105 hybrids.
The NAZPR just had a new monthly match start up near Wikieup AZ with most of the targets farther out with very few less than 400Y. Might have to rethink the 6 Dasher which I was going to do when this barrel is done.
I'll probably stick with 6x47L, been a good cartridge and past 30 cycles on the brass.

It would help but I doubt it. Nothing wrong with 243 as long as you're realistic about what it does and is capable of.I am thinking about doing a 6mm and going back and fourth on all this shit,my question is could one do a plain Jane 243 and load it down to 3050-3100 and still get the barrel life of the 6xc or creed?

I first chose a 6x47 Lapua for the sake of simplicity. Very good choice it's extremely accurate and 3050-3150 is easily achieved with N160, H4350, IMR4451, etc.
I then started reading about and talking to users of the 6 Comp Match (243 w/31° shoulder) and David Tubb released the new 115 Dtac (.620 G1 BC). I am making the switch to the Comp Match. If these accurate barrel life numbers are correct, 3000-5000+ using H1000, the change is worth it. Seems like it works like the 6.5 SAUM, lower pressure H1000 loads pushing heavy for caliber bullets in cruise control, if that's what's going on, I have to try it.

I chose 6 Dasher because all the cool kids are doing it.
Slightly less recoil, better barrel life, uses less powder, benchrest level accuracy and easy to tune. 1000 yard benchrest competition is dominated by the Dasher. Tradeoffs are fireforming and that I give up a click or two of wind to the faster 6mm's in tough conditions.

There is R700 bottom metal that takes 7.62 P-Mags?
Please elaborate
Thank you
EDIT: Nevermind. He's talking about the AICS pattern P-Mag.

OK, but along that same line of reasoning...Just thinking to myself as I read through this thread and here's what I came up with... 6mm Creed AI using Lapua brass. 105's at 3250 fps in a 26"- rough estimate.
Why not just do a .243AI, and enjoy even more case capacity, use Lapua brass, & run the same slow burn powder for long case & barrel life?
Seems like the .243AI hardly gets any love with the 'precision' crowd & I'm not sure why? Only thing I can think of is maybe only being able to fit 9rds in a 10rd mag, due to those blown out shoulders?
My necked down .22-243AI feeds fine from AICS mags, so I can't see there being a feeding issue?
The latest rage 6 Dasher has a 40 ° shoulder, same as the .243AI...

The reason I don't run a 243AI is cause you can't run AW mags. Deal breaker for me.
I have a 6x47 and just spun up a 6SLR for myself. I don't have a lot of time with the SLR the thought behind it though was cheap brass that I could leave at a match. The SLR is preforming great so far with 115 DTACs so I'm excited to try it at a match. That being said I have zero complaints about my 6x47

Ive always heard the 243ai is too dramatic in its velocity consistency to be a serious long range option.6x47Steve wrote:

I have a 6 dasher and a 6x47. Not sure I prefer one over the other. Like the little extra speed, no fire forming, and the no fuss mag feeding with the x47. The dasher is supposed to get better barrel life, but I have a friend that lost accuracy in fewer rounds than I have on my current 6x47 barrel. It's possible his was a fluke. Both have excellent brass life (lapua in both).
In my hands they shoot similarly in terms of accuracy and recoil. A better shooter will likely notice a difference, but both are great for me.

Seriously though, I think the Lapua small rifle primer 6.5 Creed brass will last longer than the large rifle primer Lapua 243 brass will because of the extra brass in the heel and then there's the .059 flash hole.
Next would be the shorter length of the case giving a bit more latitude for seating 115 DTACS or the new 110 SMK's in AI mags. I'm leaning towards going to those bullets right now when I run out of the Berger 105 hybrids.
The NAZPR just had a new monthly match start up near Wikieup AZ with most of the targets farther out with very few less than 400Y. Might have to rethink the 6 Dasher which I was going to do when this barrel is done.
I'll probably stick with 6x47L, been a good cartridge and past 30 cycles on the brass.
