Curious to see what those of you more knowledgeable than I think.

Combined with high Ballistic Coefficient (BC) projectiles designed for long-range shooting, the velocity of the 6.5-300 Weatherby Magnum is meant to open a whole new world of possibilities for competitive shooters and provide hunters with optimal terminal performance.

“We have taken ‘Nothing Shoots Flatter, Hits Harder, Or Is More Accurate’ to a whole new level with what is now the fastest production 6.5mm cartridge in the world,” states Adam Weatherby, Executive Vice President and Chief Operating Officer of Weatherby Inc., “The speed and energy of this cartridge is unprecedented and worthy of carrying the Weatherby name, all while exhibiting very manageable recoil.”

Weatherby will offer three different options in loaded ammunition for the 6.5-300 Wby. Mag. The loads will range from 3531 fps to 3395 fps at the muzzle and feature either Barnes or Swift bullets. Correspondingly, the 6.5-300 Wby. Mag. will be chambered in the New Mark V family of rifles and offered in the Accumark, Accumark RC and Ultra Lightweight models.

Sounds like they are trying to 1 up the 26 Nosler

I'm waiting for Ruger to chamber the 77 mark. II in 26 nosler

There was the 6.5x300 Weatherby-Wright-Hoyer in the 1960s.
It was very fast and very accurate in a good barrel, but the H870 powder tended to foul it out before the end of a Long Range match string of fire.
It still has some adherents, powders are better now.

I used to be a member of the "my dog's bigger than your dog" club. After a while I kinda figured out that the little velocity increase comes at the cost of recoil, muzzle blast, and barrel life. Just remember that a 10% increase in powder gives a 2 1/2% increase in velocity.

At one time Weatherby was pushing the .30-.378. Super smoker. Had a friend that had one. Recoil without the muzzle brake was brutal. Muzzle blast with it was brutal. Shot the barrel out at less than 1k rounds.

It is not new .... Weatherby just is claiming that it is ... as someone above said it has been around since the '60 ... I have a Sierra reloading Book from 1971 that has data for it ... so it ain't new!

Shot the barrel out at less than 1k rounds.

That's the problem with overbore rifle rounds, terrible barrel life.

I shot a .264 Win Mag in thousand yard matches back in the late 1960's. It would put 20 to 30 rounds inside 1 MOA at that range with Norma 139-gr. FMJBT nickel plated bullets over 72(?) grains of H870 properly tested.

It lasted 640 rounds at that level then went from that to 3 MOA over 4 shots.

I doubt Weatherby's new 26 caliber will do any better.
