The thread on the big 6.5's got me wanting a 6.5 stw since I have a Remington 700 in 338 win mag im thinking about rebarreling. Have any of you ran a 6.5 stw? What kind of velocity did you get with 120 to 130 grain bullets?

If a big 6.5 was planned, I'd wait and do a 26 Nosler.

Docs Gun Shop here in Carrollton,Texas has built several of them and 1 of the gents I was talking to uses 120gr NBTS and he was running them at 3850fps and said when it hit the deer it was like they were hit by lignting,most of them thru themselves backwards.He said he has pushed them as fast as 4015fps but they were exploding on paper at 150yds,

Do we have specs on the 26 Nosler yet or is it to shrouded in secrecy right now?
I don't mean Nosler's advertised performance figures but case dimensions, parent case, etc.

The 6.5 STW will beat the 264 Mag by the same % a 7mm STW will beat a 7mm Rem Mag. Not hard to look at a book and see what this will equate to.
4000 fps with 120s in a 6.5 STW? Somebody is either full of doodoo, or was very close to blowing his face off.

If this report is anywhere near the facts, the 26Nosler is all the 6.5 I could wish for and would be the exact ballistic equivalent of the STW or 6.5-300 Wea. http://cheaperthandirt.com/blog/?p=52201December 4, 2013
26 Nosler: �World�s Most Powerful� 6.5mm Commercial Cartridge?
by Woody
Related Topics: Ammunition Ballistics General Industry News News Rifle Ammunition
26nosler-promo-imageLike many shooting enthusiasts, the Nosler family has always dreamed of introducing a new rifle cartridge. And they�ve done it with the arrival of the 26 Nosler�a new cartridge that was submitted to SAAMI in June 2013. Formal launch of the round will take place at the 2014 SHOT Show.
Nosler hasn�t released case specs for the round, but some details have leaked out. A Nosler sales flyer says the round has a cartridge overall length of 3.340 inches and a usable case capacity of 93 grains of water.
The parent case is rumored to be the .375 Ruger, which at 99 grains of water has the necessary starting capacity to be necked down for the smaller 6.5mm bullet. Rifles chambered for the round may have 1:8 barrel twist to stabilize heavier bullets.
�I really feel the 26 Nosler has great value among the large family of 6.5mm cartridges,� said Bob Nosler, CEO/President of Nosler, Inc.
The company said the goal of the new 26 Nosler cartridge was to take full advantage of new technology available to shooters, including the advance of optics, reticle systems, and high-ballistic-coefficient (B.C.) bullets such as the company�s AccuBond Long Range line.
The company stated the 26 Nosler cartridge utilizes inherently accurate and high-B.C. 6.5mm (.264) caliber bullets, and is capable of shooting the Nosler 129-grain AccuBond Long Range (ABLR) bullet at a 3400 fps at the muzzle. Zeroed at 350 yards, the 26 Nosler has a point-blank range of 0-415 yards. Loaded with the 129-gr ABLR, the 26 Nosler retains as much velocity at 400 yards as the 260 Remington produces at the muzzle, according to a Nosler release.
Other 6.5s do fall quite short of the 26 Nosler�s published performance. Nosler itself loads a 6.5-284 Norma round with the ABLR bullet (#60128) that has a muzzle velocity of 2965 fps. Nosler�s Custom Hand Loaded 260 Remington 130-grain AccuBond #13055 has a MV of 2800 fps.
The .264 Winchester Mag in the Custom Hand Loaded line #14072 uses a 125-grain Partition to get a MV of 3200 fps, and a 130-grain AccuBond #14076 in that cartridge drops to 3100 fps.
The 6.5 Remington Magnum Custom #14325 with a 125-grain Partition scoots along at 3025 at the muzzle.
One Nosler Custom round that does eclipse the proposed 26 Nosler is the 270 Weatherby Magnum #15020, which fires a 130-grain Partition at 3450 fps.
The 26 Nosler case is non-belted, so it�s headspaced off the shoulder to enhance accuracy. The 26N also utilizes a standard .30-06�length action, allowing for a shorter bolt-throw and lighter weight than magnum-length actions.
�With minimal recoil, tremendous velocity, energy, and the ability to point and shoot at the intended target up to a quarter-mile away, this is the quintessential deer, antelope and long-range-target cartridge,� Nosler said. For reference purposes RCBS Load 2.88 shows the capacity of 300 Weatherby as 92.8 gr water, 300 Win as 86.0 gr water, 7mm STW as 92.9 grs water and the 264 win as 78.6 gr water. Which means there is no significant difference between the capacity of the 6.5 STW, the 26 Nosler, or the 6.5-300 Wea. 93 gr capacity for the new Nosler round minus 78.6 gr for the Win mag equals 14.4 gr. Which means the 26 Nosler has an increase of 18% case capacity over the 264 Win. We can expect a maximum of an 9% increase in muzzle velocity from the Nosler compared to the Winchester round. A comparison of five loading manuals on my shelf indicates that 3300 fps with a 120 gr bullet is a fair expectation from the 264 at what most of us would consider sane pressure levels. Thus the 6.5 STW or the 6.5-300 Wea, or the 26 Nosler should be capable of about an additional 300 fps. According to these figures Nosler might be loading the round down a bit in order to preserve barrel life. NOT a bad idea! Me????? I do love my 264 and my 7 STW. But they eat barrels fast enough for my taste. I do not wish to run any lower bore expansion ratio than these.

Velocity increases at 1/4 the increase in case capacity, not 1/2. A 22% increase in capacity would result in a 5.5% increase in velocity, when loaded to similar pressures.
With the 3300 fps with 120s you noted, that will be more like a 165 fps increase, not 350.

Okay, I stand corrected on the % increase. Also you will note a correction in my math. I originally misread part of the article on the Nosler round.

So, a 150 fps increase over the 264 velocity puts up pretty close to what Nosler is stating in their press release claiming 3400 fps with a 120.
And it is a hell of a long way from any joker claiming he is breaking 4000 fps with a 120 in 264 caliber.
Perhaps, with a 50 BMG necked down??????

Maybe a 6.5-50BMG with a 40" barrel!
