True. As far as the complainers go..... ![[Linked Image]](http://i1243.photobucket.com/albums/gg546/elkhunterinnm/A8FA9680-E6A2-44A2-969C-1C686B055B78-10455-000009F85E861132_zpsaf81e80a.jpg)

Simple 260 or 6.5-06 in a ultralite model would be sweet .. just thinking aloud

What a colossal waste of time when there is 1000 yard 243 already on the campfire, proving the lack of need of all this wasted discussion...
That sand up in there has got to itch and burn.

I heard about that. I also read on that thread that the .300 Weatherby isn't a long range cartridge. LOL. No you didn't read that nor did you hear that but I have no doubt you "felt" that.  I know there is a niche market for ultra performance at any cost, whether it be automotive, computer hardware, or ballistics. But most of us mortals have to settle a bit in the performance department as performance increases at a rate inversely proportional to cost.
Ultra-capacity cartridges are of little interest for ranges inside 600 or 700 yards. Extended ranges typically mean heavy for caliber bullets with high ballistic coefficeints.
Mule Deer has shown us years ago how to acheive that elusive 3200 fps with a 140 in the 264 at sane pressure.
But such loads are still very scarce in the load manuals. While the 6.5 Nosler exceeds 3200 fps by slim margins.
There is a significant performance gain in the 7 mm magnums when increasing capacity from that of the 7 rem/wea mag to capacity of 7MM STW/3OO Wea.
That performance gain is much diminished when bore diameter is reduced to 264. I didn't really want to like the 26 Nosler but the SAAMI chamber is designed much better than the SAAMI .264 Win Mag, specifically the throat. The 26 Nosler throat is still not right but won't die nearly as fast as a SAAMI .264 Win Mag throat. 3200fps/ 140gr bullet will come easier (26 Nosler) and at lower pressure, which will also benefit throat life. DF: I know you like those big 6.5's...  Gonna get a Weatherby? Naw... The 26 is big enough, burns enough powder, makes enough noise... I have only one Wby, a Mk V and it wears a Brux 7RM tube in a Wby Express McWoody. That's enough Wby for me... Jorge and Fotis are real Wby fans... DF All this talk about hot rod 6.5mm is making me think there might be something there. I might just have to give one a go.  Wonder if it will kill an elk?

This is the first time I have heard someone saying the 26 Nosler potentially having longer barrel life than the 264 WM. Care to estimate how many rounds the "average" 264 WM, 26 Nosler and 6.5/300 Wby would last?

I have more than that through my 264 WM but recently found out the throat has gotten quite long.

The original barrel on my Win 70 classic lasted 2500 rounds, but 1000 of those were 3000 fps w/ 100 gr 0r 120 gr ballistic tips and IMR 4831 as ground squirrel loads.
About five years, for me.
The only way the barrel on a 26 Nosler or a 6.5-300 Wea will outlast a 264 barrel; is to hold the velocity of the bigger cartridge to 264 levels. As John Burns stated in his post.
The 26 Nosler pushing a 140 to 3200 fps with 869 will run at a lower peak pressure/flame temp than will the 264 pushing the same bullet to 3200 fps with Magnum or Retumbo.
But, how many purchasers of the two larger capacity cartridges will settle for running them at 264 velocities? Most will be striving to hit 3250 at a minimum or 3300 fps.

Interesting. Most would want to hot rod the two bigger rounds but I would be happy with longer barrel life and run them at 264 WM speeds.
I have used mostly Retumbo since building the 264 WM in 2008 but can't complain with how long the barrel has lasted. Still shoots decently but I need a lot more powder now to get the speed I used to.

Like some others have posted here. I would run them max as it is a hunting rifle and I wouldn't run that many rounds through it each year. Probably last my life time, but 223 dog town rifles are a different story.

Yours is not a unique mindset. I do not run my 6-284 or my 22-243AI nearly as hard as I might. But they still exceed the rifles' original chamberings of 243 Win and 22-259 Rem. Dr Howell promoted a whole series of oversized cartridges, not to maximize velocity, but to reduce chaber pressures.

I've got a 257 Weatherby and a 270 Weatherby. I've been hoping for something to fill that performance gap.
EUREKA !!!!

The .264 Win Mag seems to be making a comeback. The 6.5x68mm is better than the 26 Nosler and better than the 6.5-300 weatherby. John, how do you feel about below: You're right, the most direct comparison is against the 264 Win. Mag. Craig Boddington once wrote in Safari Rifles about the 6.5x68mm and said, ...the velocities are wonderful-about the same as or better than the .264 Winchester Magnum without the magazine-capacity-devouring belt. If that's the case (at or better than the .264 Win. Mag), how might it compare to the .270 Win at long range? Can it use a shorter barrel like the .270 Win eg 22-23" or as you and I suspect, must it have at least 24+" to produce significantly higher velocities to gain an edge over the 270?
