I get 2900fps from a 22" .260 Remington pushing 123gr.
Hodgdon's max load data for 123gr SMK is 2937fps from a 24" .260 Rem.
I know some guys that wildcatted the 458 SOCOM down to 6.5mm, did all kinds of things, ran into all kinds of problems. They got insane speeds, but something was wrong and it was scrapped last I had heard.
Remington missed the boat by making the .30 RAR .30 caliber. Should have been 270 RAR, 6.5 RAR, and .257 RAR, with an urge to get the industry to dust off the .257 projectiles.NRA Basic, Pistol, Rifle, Shotgun, RSO

They tried necking down .50 Beowulf too.
That .30 RAR would be an interesting case to work off of, understanding that mags are single stack at that point.NRA Basic, Pistol, Rifle, Shotgun, RSO

About to get started on a .264 with a .473 head diameter for the AR-15. Its going to be based on nato brass, with the option to use other brass such as 6.5x47L and maybe Norma Dasher. case length will be around 1.570" and will be able to use all but the longest VLD match bullets at or less than 2.260" OAL. It needs a name. Like with the Mongoose, you guys get to name it.
Middle cartridge, below.

The Timberwolf is the brainchild of Mad Dog Weapons. He does good work. I have a Wolverine and the hard hitting Yeti.
The Timberwolf is still in development and I believe it is based on 6mm Norma Dasher brass with a 43 grain case capacity. Initial testing showed 2950fps at the muzzle with a 123gr pill. Looks to be capable of 85-140gr projectiles.

It most likely will not see production for quite a while yet.
