How many here are seriously interested in the new 6.8 Western?

We can’t even get ammo for mainstays like .308 or .300 win mag, why on earth would I buy another new caliber right now.

And why is the twist rate on the barrel so much faster on it?

As has already been mentioned, the twist rate is need to stabilize heavy bullets. To make a bullet heavier they have to make it longer. There are several reasons to make bullets heavier, the two main ones are:
Penetration
Higher ballistic coefficient (which basically helps with wind deflection). Wind normally isn’t an issue unless you are shooting past 250-300yds.

Not a chance

So why are all barrels in other calibers have 1:10 or 1:11?

Calibers or cartridges?

In other cartridges like the .270 win the heaviest bullets you can find (production) is what 150gr? Faster twist isn’t needed to stabilize that.

All I know is if a machine puts out 1 rd/sec, out of a dozen one is loading 6.8, and no two machines are loading the same caliber, it's being loaded at the same rate. That only applies to one manufacturer, though. And its likely that this cartridge will not be off the machine for many many months. The same thing happened with the last new caliber launch

Yeah I’ll call bullshite on this. Why would a business retool and recalibrate to produce some new round “at the same rate” when they cant make their product fast enough at all as it is.

Many, many years ago, before there were Spitzer (pointed) bullets you needed a really long bullet to have anything resembling a decent BC and longer range capability. To stabilize longer bullets you need a "Fast twist". Fast is relative, the smaller the bore the faster the twist needs to be. The three most common military calibers were .308, 7mm and 6.5mm and they all had fast (10" for 30 cal, 9" for 7mm and 8" for 6.5) twists to stabilize long bullets. The soldiers that handled these military rifles often used them for hunting when they got back home and the longer heavier bullets worked significantly better on game.

Decades passed, Spitzer bullets are invented, bullets are made better (still not great, but better) and optics start appearing on firearms. With optics, skilled rifle shots can take advtange of point blank aiming out to longer distances (2-300yds). Because bullets are made a little better, and you have moderate BC's with shorter lighter bullets, you don't need the real long heavy bullets anymore. Faster, flatter shooting bullets like the 130grn in the 270Win become the new favorites to extend maximum point blank range. Max point blank range is really important because estimating range is very difficult w/o training, mildot reticles and even then it's iffy particularly on game that can vary tremendously in size.

Bullets are better, but still not great and the smaller a bullet is the harder it is to make precisely. Overstabilizing these imprecise bullets leads to accuracy problems, so the "new" chamberings have the min twist necessary to stabilize the heaviest bullet commonly shot in them. Things stayed like this w/ moderate incremental improvements until the invention of laser range finders.

Now with laser range finders, range estimation is easy. With precise laser range finders, scopes that will dial properly and accurate ballistic calculators "flat shooting" doesn't really mean much. If you know how and have the equipment anybody can make easy hits on target out to 600yds or so - as long as the wind ain't blowing! And the wind is always blowing out west where longer shots are more common.

Now things come full circle, rifles w/ fast twist rates and long high BC bullets have the most resistance to wind. So, the 10" twist 30 cals, 9" twist 7mm's and 8" twist 6.5's again are back in vogue. Bullet technology has improved so much there really is no downside to fast twist. If you shoot 120grn flat based bullets in your 6.5mm CM they will still be accurate.

People have been building fast twist rifles for years to take advantage of the bullets available. Up until recently there weren't a lot of bullets available in chamberings like the 270win that could utilize the faster twist. That's changed. There are real long, high BC bullets available for .277 (270), 25's, 6mm, 22's etc. and people are now building rifles w/ fast twist barrels to take advantage of these bullets.

The 6.5 Creedmoor was so popular because the factory specs had it being built the way it needed to be to be effective out of the box with no modifications. The success of the 6.5CM has manufactures attempting to cash in on that success formula, the 6.8 Western just makes the 270wsm what it should be, out of the box. There are no negatives for someone shooting at a whitetail at 60 yds in the woods, but there are a lot of positives if he decides he wants to go elk or mule deer hunting with that rifle and needs to take 300yd+ shot in high wind conditions that are very common.
