Home Forums Hunting & Shooting Hunter's Campfire load info for 6.5mm-.300 Weatherby

I have a hankering for a new chambering. Can anyone give me load info for 6.5mm-.300 Weatherby. I will use a 26" 8 twist barrel; if that is needed info.

I have G.S.Custom 106HV and Lapua 123 bullets. Maybe some real heavy bullets would be best for this cartridge.

Any info will be appreciated.


Edited to add: I heard the 6.5 STW has the same case capacity.

Probably advisable to keep a couple extra barrels on hand!

I figure if I run the 106HV at 3,750 feet per second the pressure will be low enough that the barrel wont burn out quite so fast. Burning out a barrel will not be a new thing for me, though.

lol, it'll still burn fast...

Sierra book had data last I looked. I run 7x300 wtby but believe much more in heavy bullets for long shots rather than light...

I believe one of the old Sierra manuals, published around 1971, has a few loads listed for this cartridge.

It was originally known as the 6.5x.300 Weatherby-Wright-Hoyer, back in the day, and was used by some shooters at the 1,000-yard matches at Williamsport, PA.

Jocko hit it, from my 1971 Sierra manual:

86-88 grs x283 powder, Fed 215, 140 gr MKHP

82-84 grs H870 powder, Fed 215, 140 MKHP

79-81 grs H570 powder, Fed 215, 140 MKHP

best accuracy all loads in the middle, and no velocities given . Magnum Man

I think two of the three powders are obsolete.

Thanks, guys, but never mind. I can't find any brass. I already have a bunch of 9.3X64, so will go with it.

Ringman ,I've never seen x283 but still have H570 and H870. It's not the powder that is obsolete but the cartridge. There are better ones to look at like the new 26 Nosler, the 6.5 SAUM, and a long throated 264 Win Mag. But if IIRC fire member Deertracker's little brother shoots a 6.5 WWH for hunting maybe Deertracker can give you some more info. Haven't seen any posts by him in a long while someone needs to wake him up. Magnum Man

There is the "new" 26 Nosler.
Will that fill your need?

6 THINGS TO KNOW ABOUT
THE 26 NOSLER

The 26 Nosler is a non-belted, 6.5mm centerfire rifle cartridge.

Designed with a maximum C.O.A.L. of 3.340�, the 26 Nosler cartridge functions in a standard (30-06 Spfd.) length action.

The 26 Nosler is capable of firing a 130gr bullet at a Muzzle Velocity of 3400 fps.

With a useable case capacity of 93 grains of water, the 26 Nosler outperforms the 264 Win Mag by over 200fps with a 130gr bullet.

Zeroed at 350 yards, the 26 Nosler has a maximum point blank range (PBR) of 415 yards.

Loaded with the 129gr AB-LR, the 26 Nosler retains as much velocity at 400 yards as the 260 Remington produces at the muzzle.

Huntsman,

Wow! Thank you for going to this trouble. I enjoyed reading and responding.



No. The neck is too short for maximizing the throat life.



Belts don't bother me. In fact one of my wildcats is a .224 MBOC. That stands for .224 Magnum Belted Of Course.



I purchased a long action for this build.



I expect that performance from a 6.5-.300 Wea.

The height above sight is too high for my taste. I don't want anything above 3" at any point.



This sounds like it matches the 6.5-.300 Wea. with a barrel that wears out sooner.
