    Looks very similar to the 26 Nosler.

    I love 6.5 caliber rounds, but I don't get the 6.5 "ultra mags." They would benefit greatly with some bullets heavier than the 140's currently available. I read somewhere about somebody making a 160 gn high bc bullet, but haven't seen any around yet.

    Agreed. The 6.5 in 160 gr RN is a serious combination. 160 gr high ballistic efficiency bullet, doesn't Berger do a VLD? , at 3000 MV would be extremely interesting.

    I recently ran into this while looking for a new rifle. I read on THR that the 6.5 is the "Goldilocks" caliber with the right many great bullet choices for hand loaders.

    I had borrowed a friends .270 Wthby to work up hand loads. He also owns a .300 Wby. Both are very nice rifles. I am working up loads later today, ready to charge cases.

    I was on the Weatherby site looking at the .257 Wthby as maybe the rifle I should purchase for deer hunting.

    Do not get me wrong, Weatherby make great rifles. 6.5mm is a great caliber. But all things considered, the 6.5 caliber is pretty crowded already. Do you thing many shooters will spend $1600, $1800, $2000+ on a new cartridge rifle?

    How many years until this cartridge is deemed a success or fades away?

    The 6.5x300 WWH (Weatherby Wright Hoyer) was a 90 day wonder in the 1960s.
    Developed for Long Range target shooting, it was very frustrating to its developers.
    It shot marvelously flat and close to the wind, but it funneled so much slow burning powder (H870 I think) down a small hole that it would not go the 20 rounds plus sighters of a NRA match without cleaning. They ruined barrels with fouling so hard and heavy it could not be removed.

    I am sure better powders are available now, but barrel life will still be short.

    Nothing new about it.

    Like the 7mm RUM, it's too far over bore capacity; very inefficient, and hard on barrels. Modern metallurgy will prolong barrel life some, but like 7mm RUM vs 7mm STW in 24" or 26" barrels, you're still not gonna see any real world performance gains over what a smaller case could do without running a really long tube.

    I don't think there's a doubt that they are chasing the early reaction success to the 26 Nosler (and shortly thereafter 28 Nosler). I agree with posted above about pricing, $1500 + for this in a weatherby rifle? Even the Patriot rifles are up there in price.
    With the knowledge and quantity of smiths out there you can get an action, bluerprint it, barrel, chambered and threaded, nice trigger, and stock for under $1500. You can get a Ruger American in 6.5 Creedmoor for under $400.
    I guess to sum up my rant I hope they bring this out in an OPP Vanguard to get it into more hands of shooters to at least test it. Heaven knows we will be tired of uttering the syllables six point five by three hundred Weathery and sticker shock from their ammo prices.

    I love 6.5's and innovation, but didn't we go through this whole Ultra-mag thing a while back?

    that 6.5 as was said held world record 1000 yard groups for years and even up thru the 80s was the hot caliber for 1000 yard competition. It was later found that less is more consistent and less problems.
    I still shoot a .264 Win Mag for antelope and deer to long ranges under certain conditions

    I think this is more for the gun shop commando that buys one, takes it home and puts it in his safe. It's fodder for the "my dog's bigger than your dog" debates.

    I knew a guy that had a .30-378 Weatherby. Accuracy went away at about 900 rounds, and this is most likely about the same. Tried to sell it. When you figured that a new barrel was about 2/3rds the cost of a new gun, there wasn't much interest

    I once saw a real life example of a .224-20MM cartridge. I chuckled, which is exactly the affect the owner who made it was looking to evoke. As to Weatherby's new-to-production 6.5-300 Wea Mag, and their Mark V rifles, I'm still baffled. It will be interesting to see how many rounds the barrel can deliver before going back for a re-barrel.

    For me, I'll stand by my .22LR, .30-30 Win and .308 Wins all day, shooting for decades. Yes, I do have a Fibermark in .300 Wea Mag, and I have owned several other Wea Mags. Those can do damage enough for my likes. When my .300 Wea Mag goes south, it will be rebarrled as a .300 Win Mag. I suspect that even such treatments as Black Nitride will do little to prolong barrel-life in cartridges the likes of 6.5-.300 Wea Mags, etc. This is going to be interesting!

    JMHO,

    Geno

    you could probably go pick up a PO Ackley book and he already played around with something similar...

    heck doesn't Lazzeroni have a caliber like this already?

    already been said...will be said again...really nothing too new under the sun as far as caliber/cartridges goes.

    Why go with such a small case?

    I have a 6.5 Rem Mag. Ballistically very similar to the 6.5x284. Not in the ballpark of the new Nosler or 6.5x300. Mine has excellent 1 shot groups; more than that and there's no telling. I've never figured it out.
