New Weatherby Cartridge!

Nothing new here. I have a gun that I have progressively rechambered from 264 WM to 6.5-300 WM to 6.5-300 Wby to 6.5 RUM. If you want to be able to go from 3100 to 3500 fps with a 140, that's what you have to do. If you want long barrel life, buy a 260 Rem.

I liked the 6.5-300 WM the best - it's essentially a 26 Nosler.
 
Introducing a belted cartridge in this day and age seems so quaint. :)

What was the last belted cartridge introduced? What was the last one that actually NEEDED a belt? 450 Marlin?

An example of a modern belted case, where the belt is actually necessary, is the .500 Wyoming, Freedom Arm's propriety revolver cartridge. The belt in lieu of a rim keeps the cylinder diameter a standard size, unlike the massive S&W X frame guns chambered for the rimmed .500 S&W. Legitimizing the 6.5-300 Weatherby has been a long time coming. Now to get a version built on the .378 case to be the first commercial cartridge capable of 5000 fps, which is the theoretical limit with our current propellant technology.

As a velocity junkie, I think its awesome. Now having said that, will it do anything my 257wby wont do to reasonable hunting ranges(inside 500y)??? Im not sure, Than again Ive never drank the 6.5 cool aid yet... maybe this will be reason to do so. Brass will be much cheaper than the 26nosler, 300wby brass is every where. Will be interesting to se how it falls into the sales market.

The 6.5-300 WM is essentially a 270 Wby.

It's actually not. The 270 Weatheby does not use the full sized 300 Weatheby case. It uses the smaller case capacity seen in the 257, 270 and 7mm Weatherby cartriges. The 300WM is the full sized case. As such, the 6.5-300 will definately out-perform the 270 Weatherby. For all practical purposes this is probably not neccessary... but the bullets will sure move:)

Weatherby,..what will they think of next?

Throat erosion and bang flop are Weatherby trademarks, not Winchester with the .264 and these terms can be found as such in most dictionaries under "See Weatherby".

Geez,.. Roy and company were doing this and hammering anything that moved when most of us were looking around in thickets for our double lung shot 30/30Deer.

And then 70 years later,.....Nosler invents a screamer that bang flops all that strays into it's tracker beam. I say fooey,....it's been long time done. If .22LR was the low point and .50BMG was the high water mark, the man who totes a .300Weatherby Magnum, may be carrying one of the most versatile tissue shredding, sharpnel delivery vehicles yet invented.

The 300Wby had the balls 6 decades ago to do all that seems to be the craze today with 1200, 1300, 1700 yard kills on big game, it was merely limited in yesteryear to it's glass, bi-pods and ballistics programs and more importantly mind set.

President Truman had a plaque on his oval office desk that read "The Buck stops here",.....well Roy Weatherby envisioned in his head some 70 years ago, that "The Buck flops here".

All Hail the Wby magnums, Father's of the modern 2 km big game rifles and being the original barrel burning, cheek jolting, shoulder cracking and scope cutting beasts, that projected "hydrostatic flop" on anything inside of a quarter section.

The 6.5/300 will no doubt continue the Weatherby reign of terror on any game animal unfortunate enough to stray into the open with a line of sight between it and the Weatherby rifle.:stirthepot2::stirthepot2:

I should probably buy me one of those Wby magnums before I dies, no?................... Oh wait, I can't even take my old 7mmRM on the bench anymore, so the Big 300 would bang me all over hell's half acre.:p:p

The 6.5-300WM is the 6.5-300winmag.
 
Just received the Canadian Direct Dealer pricing/product list from Weatherby this morning. The 6.5/300 wby will be available in the Arroyo, Arroyo RC, Outfitter, Outfitter RC, Terramark, Terramark RC, Accumark, Accumark RC, Ultra Lightweight, and the ammo will be three loads, 127 gr Barnes LRX, 130 gr Swift Scirocco, 140 gr Swift A Frame, and brass will be priced the same as the cheapest Weatherby brass (currently $49.00 or so) My apologies if this information is already posted but we just received the new list hours ago.
 
Hard to get excited about another cartridge + rifle combo that falls 150fps short of my 7mm STW with all bullet weights. No doubt many wild tv watchers will be twitter patted by it.
 
Is WBY offering a sub MOA guarantee like Nosler is with their 26 Nosler? Or is WBY sticking with their 1.5MOA accuracy guarantee?

Wby's Range Certified accuracy guarantee is .99" at 100 for 3 shots according to their webpage.

Looks like the new Mark V's will all be guaranteed sub MOA according to www. americanhunter.org/articles/2015/9/29/weatherby-introduces-the-new-mark-v-rifle
 
I guess WBY has seen the writing on the wall and decided to step up it's game. WBY brought velocity and the concept of "high quality" to the game decades ago, but I'm sure they have seen their market share plummet in recent years. WBY had always appealed to the high end market, but these days people that want good stuff have way more options and want precision.

"Double radius shoulders" and "freebore" are so old school that few will still fall for that nonsense anymore.

WBY has painted themselves into a trap. WBY style cartridges are not in favor anymore, and for good reason. I doubt this cartridge will catch fire. It ain't no 300WSM or 375 Ruger ;)
 
To the ego strokers whom are saying it's not new, where have you been buying your factory Weatherby 6.5-300 Magnum ammo, all these years? :jerkit:

Who buys factory ammo at all?

Most everything had been necked up and down and shoulders have been blown out and moved in every which direction. Just like the 338-06 wasn't "new" when Weatherby decided to chamber rifles for it, so to this new 6.5 is nothing new because it's been done before...way before.
