Forming the false shoulder and fireforming. Unless you're using Norma Dasher brass that seems to be the way most people load it: http://forum.accurateshooter.com/threads/6-dasher-fire-forming-false-shoulder-step-by-step.3918893/
I'm just saying it's extra steps I personally don't want to do. Are you guys not forming the false shoulder or are you using Norma brass?

I bought Lapua 6BR hydroformed into Dasher brass. After doing the math paying for hydroforming was a little less than cost of the bullet+primer+powder I would've used for one round of fireforming. The hydroformed brass was 100% load and shoot, and was consistent enough that I used it in a couple of matches.
Theres are so many variables it's hard to say on barrel life for a caliber. I hate to say this but I went the route of 6 comp match. Very small following but I have been very happy on barrel life
In a gay way?6gt looks much sexier than creed..
BRA is a bit more forgiving when fireforming by all reports.
You don't need to jam bullets or create false shoulders with BRA. Because you are only changing the shoulder angle and not actually changing the shoulder position the process is easier on the brass.
The first loading of 6BRA is essentially 6BR, then after that you get the BRA velocities. No split necks, and the accuracy is incredible with the FF loads. You can shoot matches with 6BRA FF loads.
You know Dasher and Dancer and Prancer and Vixen
Comet and Cupid and Donner and Blitzen
But do you recall
The most famous reindeer of all?
Rudolph the Red-Nosed Reindeer
Had a very shiny nose
And if you ever saw it
You would even say it glows
All of the other reindeer
Used to laugh and call him names
They never let poor Rudolph
Join in any reindeer games
Then one foggy Christmas Eve
Santa came to say
"Rudolph, with your nose so bright
Won't you guide my sleigh tonight?"
Then how the reindeer loved him
As they shouted out with glee
"Rudolph the Red-Nosed Reindeer
You'll go down in history"

how long does an extra step take? after fireforming you just load and shoot it 10-20 times. Unless you are going through thousands of rounds of brass prep every year with a Dasher...it's no big deal.
Their are some more advantages of the GT over some of the others. Here are some of the reasons for its development
No feeding issues out of a non modified mag (yes some don’t have issues with dasher, but lots do especially from an aw/ax double stack)
The ability to run varget over h4350. The size of both the creed and XC lend to h4350 burn rate and fill capacity being better. Varget is just PFM. One of the reasons dasher shoots so well. And 6.5x47.
35 deg shoulder and case design (hardness and overall wall thickness). A case is not a case. Internals matter.
Available brass without having to fire form. GAP is also going to try and start this out right without 5000 different readers from guys who “know best”. This should help keep everything where it needs to be.
Now the real question is how will the market react if there is quality GT and dasher brass available.

How's that going? Of the barrels I saw torched in 6 comp, they ranged from 1200-1800 rounds. 1800 had been making it stretch out for a couple hundred rounds, too.
Listen to the right people and it's "3400fps and 3000 rounds with a 105"... I've never seen either of those.
I run a .243AI shooting H1000 with 105 and 115 bullets. Pretty much the same concept as the 6 comp match. I don't push it hard. 3170 and 3050 respectively. The first barrel was done at 2500 rounds. I tried to milk more and pulled it at 2800 after shooting really shitty at a match and taking it to the range to find it wouldn't hold vertical at 800 yds. The second barrel is at 1400 rounds. It is still shooting sub half moa, but the throat has advanced a bit and I had to chase it and add powder to get the velocity back at around 900 rounds. For the amount of powder it takes to get that performance I'm thinking there has to be better alternatives. I'm going to burn through two more barrels and then evaluate if I want to go a different route. Then I'll have a better idea of what the average barrel life is, so I can compare it to whatever I try next. I think to get 3400 fps out of it a guy would have to run a 30" barrel and a shitload of pressure. In my opinion that is likely to make the barrel life very poor.
Alpha Munitions has a waitlist for the new Redding 6GT Type S Match Bushing dies and GAP has the RCBS 6GT Matchmaster dies. The Redding dies are going to go for $289 while RCBS is only $163.54. I'm trying to decide between Redding or RCBS.
Big difference in cost. Noticed George is selling the RCBS with the bushing. The Redding bushing will be another $20 for steel and $30 for ti.
I have a couple of Redding Match S bushing dies for different calibers. Never tried RCBS. The price is a lot more appealing though and I can use that extra $100 I'd save for the brass or bullets.
Ya little over $300 after shipping plus you have to find a bushing. That's another $20 to 30 + shipping. Would have close to $340 in just the dies. Or I could try the RCBS for $164. GAP wants $18 to ship to me so $182. ( was pulling the trigger on these until I seen the $18 shipping). Still leaves me $158 for brass. I'm thinking brass will be about $1 to $1.10 each so 100 will be $110. Going with the RCBS I will have Dies and 100rd of brass and an extra $58 in my pocket for another 100 rounds of brass.
As you can tell I'm trying to justify buying the RCBS but all this math is making me wonder if I really need another caliber at all! Haha!

I went with the RCBS dies. Same reasoning it's a little cheaper so I can use that extra money for brass.
If you guys didn't see it, Alpha has been taking pre-orders and is now taking regular orders for brass, $115 per hundred.

Area 419, NSS, Paradigm Gunworx, and probably many others offer 6 GT prefits. Supposedly X-Caliber will be adding it by December.
Exactly my results, and I agree with your comparison to h4831.
