Just announced this morin.

Dammit. Now I'm gonna have to get that 25-06 barrel after all! .334 G7 looks better than a 19yo pair of titties....

Go figure. The quarter bore crew is excited about the new heavy bullet developments while the 270 crowd is pissed off Winchester is trying to introduce the same in the 6.8W. Oh well, looks like it's time for a .257 something build

Great!!! but will this bullet kill an Elk??

Got a 700 LA here waiting for a new barrel, got 7 Wby brass. How about using 7mm brass necked to 25, 7.5 twist PAC-NOR. Or should I just go with a 257 Wby. fast twist?? Lots to think about..Maybe a 25-06, 26 inch tube..gotta get some of these new bullets..play with seating in dummy rounds...

Looks like Pete and others got their wish...

If anyone is going the fast-twist .257 bore diameter route:

110 Super Bulldozer

Mine is a 1:7 benchmark barrel 26" in a Ruger #1. Caliber 25-06 AI

Still waiting for gale winds to die down.

I've got 131 gr Ace Blackjack and Hammer 130 gr bullets

No reason for the 25 not to have the BC of others.

I haven't sit down with all the BC & recoil numbers, expected barrel life, etc. etc. but should be in the running with the rest.

25's can kill things, BTW.

I mentioned this in another thread.....I am hoping someone will take the 6.8 Western case and neck it down to .257 caliber. Maybe Winchester will eventually...yet doubtful

Hang in there guys. Just a bit longer and i'll have permission to share a new Barnes bullet.

Be advised, you're in the "long-range" forum... Barnes ain't never made thing (!long-range) or worth a fuuck period...

May i make that comparison please? Purely scientific of course

Anybody do the math on that yet...what's the minimum twist at expected velocities?

Care to elaborate or share your experience/s?

You're going to have to supply your own samples for comparison. As it is, my memory is getting a bit fuzzy.

My .257 bee has a 1/9 twist Bartlein. Wondering if this would give me enough rpm's?

Per Bergers stability factor chart, you just make it. 9.25 is marginal. Look it up.

Thanks, I forgot about the calculator.

With a recommended twist of 7.5, you think it will sell? I think the twist for the majority of .25's has kept high BC bullets from being developed (able to sell).

Might be a custom barrel only bullet.

i think my 257 Creedmoor with a 7 1/2 twist barrel is going to shoot those Berger 135 gr 25 caliber bullets great. i also have to agree what Judman posted, i too have never have had Barnes bullets that shot very well at long range ever either.

At sea level and 3200 fps your stability factor is 1.17
Minimum Twist Recommended: 1 in 7.75"

I don't know about that. My 30-378 Bee slings 175 LRX's at 3450 fps. It shoots flatter than Kate Hudson!

Can't deny that would work waaaay out there. Not my cup of tea, but you are welcome to enjoy it.

I'd rather look at Kate fwiw.

All this over an extra 10-15 gr weight? Wow....must have a really pointy nose on that thing.

Yeah, can you imagine a 250 AI with the ballistics of a Creedmoor?? That would be something!

25 PRC might be a fun little project......

Long time back there was a gun loony that had a wild imagination. As I recall he went to a 5-5.5" twist for the Roberts and loaded it with 150 gr bullets. Mebbe he should'a used a .25-06 or .257 Bee?

I am going the 257 Weatherby route. I get different info on twist rate, Black Jack says 1-8" but others say 1-7". Any down side to 1-7"?
Will the Bergers hold up at Weatherby velocities?

There was a series of those long bullet cartridges in 22, 25, 6.5 and I think 7mm. They were called the Arch or Condor depending on the creator. One account was of a hunter putting a 125 grain 224 bullet through both shoulders of an elk. Barnes made the bullets out of copper tubing.

https://bergerbullets.com/new-25-caliber-135-grain-long-range-hybrid-target-bullets/

Was hoping these were the Hunting bullet, but the heavier jacket of the target style may be a plus at the ranges I shoot. If anyone finds where to get these please PM me as I bet they will go fast.

Just saw that they have a 133 grain hunting version too, it is not even on the Berger web site. McGeegunstocks.com is taking pre-orders but they are selling mostly the 500 box. I will see if I can get the 100 boxes to test before getting 500 of them.

Good Bullet for my 1-7 257 STW

The big 25s are hampered by wind drift way more than trajectory. These and other high BC bullets could go a long way to correct this. These will also make the smaller cartridges shine and competitive with the6s, 6.5s and 7s.

fotis.any range report yet.interested in your findings.

i just have had a 257 Creedmoor built with a 7 1/2 twist shoots great now with the custom dies, i also have 2 new 257 Roberts with a 7 1/2 twist barrels all 3 are Brux S.S. barrels the 30 Rem.Express that i had chambered 257 Roberts 71/2 twist barrel shoots excellent, the other one is a real nice Mauser i had rebarreled in a 257 Roberts 7 1/2 twist Brux barrel for my daughter but this rifle is waiting for me to pick up ,but since i had this back surgery it will be a while before i pick up this mauser 257 W. Mag.. i am thinking and wondering about building another 257 Weatherby mag. chambered ? looks like the best way is to buy a used Weatherby Mark 5 accumark rifle and rebarrel with a 257 Weatherby Mag. 7 1/2 twist Brux barrel for the best accuracy and cheaper too maybe a 28 inch barrel length ? maybe be able to get 3400-3500 fps. with the new Berger 135 gr. bullets ?

I just ordered a seven twist 25 barrel that will get reamed to the Weatherby chamber. The 7.5 twist should work but the 128 Hammer bullet needs the faster twist. I don't think I will regret the 7 instead of the 7.5 twist, although Black Jack recommends the 7.5 twist for their 131 gr. bullet.
