I am hoping the 25 Creedmoor has an appropriate twist rate of one in 10.
I could live with a one in 12 too, I guess.

My Bartlein has a 1 in 10 twist.. It allows use of the Berger 115 VLD and gives sub 1/2 moa accuracy..
Also used 85 and 100 grain ballistic tips with good velocity and accuracy..
Just recently have used Hornady 110 ELD-X’s.
So far I haven’t encountered a bulletin rifle won’t shoot..

The .25 Creedmoor will probably appear after today's incredibly high-level demand for the .25 Souper, .250 Ackley Improved and .257 Roberts dies down.  I have wanted a 25 Souper for probably 30 years, but never quite got around to building one. When the 6.5CM came along, the practical side took over and I said "that's close enough". Great factory ammo, lots of rifles to choose from, high BC bullets. Hell, it's better than close enough 
FÜCK Jeff_O!

When are we going to see a 25 Creedmoor? For the 25 fans. It would basically be a .250 Savage AI................which would be pretty cool. what we really need is a 5.926548 creedless ackley disapproved with Gibbs front ignition, rimmed, dinodestroyer.....you know.....something totally new and something we haven't had at our disposal for many years I'll start work on it if you'll buy shares in the company!

Greg,
Speaking strictly for the 257 Roberts necked up to 6.5 mm...the 6.5 x 57..
on a long action, in a modern pressure rated action...it has a lot more potential than
any 'lawyer safe' load data would suggest...without stressing anything...
it will run with a 6.5 /06 all day long....
I still can't figure what a 6.5 Creedmoor or 6mm Creedmoor offers over
a 260 Rem, or a 243 Win, when equipped with the same barrel twist etc...
but latest greatest seems to still sell to those that have to have those things..
I'm of the other camp.. if its been working for 20 to 60 yrs... why do I need to reinvent the wheel...

Nothing new here.....the .257 Roberts was necked up tp 6.5 mm to work in some of the Japanesse Arisakas after WWII surplus rifles hit the market.....The Japanese Arisakas weren't ALL dumped into Tokyo harbor as was the case with boatloads of them.

Seafire you’re right, of course, all these rounds are in the same camp..
Doing something different every so often keeps me engaged and interested.
For me, the quality of the 6.5 creedmoor lapua brass was enough the get me moving——

Jim,
Why a 1-10 or worse yet a 1-12 twist?
If I were to build one it would be a 1-9 minimum or better yet a 1-8. My current two .257 Roberts have 1-9 twists and I am wishing they were 1-8's. I was too conservative with the twist rates when I ordered the barrels. Bullets are getting longer, not shorter. The two 1-9's shoot 75 grain bullets into as small of groups as the 1-10's ever did.

For me the lapua brass with a small primer pocket, like the 6.5x47 lapua, allows you to run higher pressures if you are so inclined. The small pp offers more resistance to case head expansion than domestic brass in the above mentioned cartridges. IMO, the lapua brass also uses a better alloy which allows higher pressure before you encounter pressure signs like hard bolt lift, brass flow into the ejector pin hole and excessive case head expansion..
The only benefit to all this is higher velocities, if you wish...
I also have chambered rifles in 6 creed and in 6.5/47 lapua as well as that case necked down to 6mm..
All fine rounds, as are the rounds mentioned earlier in this thread. If higher velocities is the primary goal, why not go with a case that has more capacity, like the 25-284, 25-06, or 257 ROY? What magazine and issue is your 25 Creedmoor article in?

I put together a dedicated varmint rifle in 25 WSSM with a 1-14" ROT in 2006 with the intention of only shooting 75, 87, and 90 grain bullets. The idea was that the slower twist might lead to a longer life, but it has less than 2,000 rounds fired so the end is not yet in sight.

Well I have a bunch of .25s so what is one more.....practicality be dammed😄. Can go to the 25-264 improved if I want velocity and the .256 Winchester Magnum or the .25-20 if I want to slow it down. Guess different is pretty much just that......the 250 Savage really has it covered (for me anyway) - but what’s the fun in that?

Has me confused with someone else, I didn’t do the magazine article. In fact,I would like to see it too.
For whatever reason I prefer short actions. Highest velocity in a .25 wasn’t the goal for me. Highest velocity that a case will give with good accuracy is..

I am a lonely and misunderstood fan of the 25 WSSM. Just 'cause it is a short fat 257AI equivalent doesn't make it less than what it is, it is just a different vehicle to get to the same place. Well that and it gets as much love as a red headed stepchild from those who don't embrace it.

Actually 260Remguy don’t feel too alone I really like my two 25WSSMs.....especially the Browning Mountain Ti when I’m still hunting in the “big” woods of PA or trekking out west for whatever. ......and 25 Creedmoor don’t get me wrong I’m all about practical hunting accuracy - velocity just for the sake of velocity has never been a goal.....just need to hit where I aim with whatever I’m using (and quite often it’s a 250 Savage or a reasonable facsimile 😊) PennDog

You're just too dog gone practical, John.  Rifle loonyism demands we look past practicality, with an eye on duplication and replication.

Or, if there’s a better mouse trap consider embracing it!
Coming from me that’s laughable as I’m horribly conservative!

What bullets are you shooting or wanting to shoot that need a 8 or 9 twist?

Problem is that to get those twists, you generally have to go custom or buy one of the very few factory rifles set up like that. Some also think the 30 degree shoulder will give somewhat longer barrel life, and there's always the problem of long bullets in short magazines. I chose the 6CM for my Barrett because the only .243s they had were 18" threaded ones. Once the pain of buying new dies is over, I'll be fine. More choices is always a good thing, and I don't get butthurt about stuff that competes with my favorites. It's all good.
What fresh Hell is this?
