338 Creedmoor / 8.6 Creedmoor

[Danilo]

so... Q has been posted some random IG stories of a 8.6 silencer being made. and today this post (pic) showing their "Fix" Rifle with silencers and the caliber is 8.6CM or 338CM.
Anyone know anything else? Maybe someone at SHOT will see something at Hornady.

Kevin, when will factory ammunition and brass be available?

 

[m6z]

What are the goals for this round? Will there be factory subsonic ammo available? Long range capable? Primarily for hunting?

 

[Kevin Brittingham]

Yes, from Hornady, and others.

 

[Kevin Brittingham]

Goals for 8.6CM are to become the big brother, essentially, of 300BLK. Awesome supersonic and subsonic performance out of a short barrel. Expanding subsonic. Accuracy. Functioning of gas guns with both supersonic and subsonic ammo. Lethal. More energy with the supersonic out of a short barrel than 308 out of a long barrel.

Yes, Hornady and others (likely everyone), will make the ammo.

Long range? Not "long", but long enough for most things.

Hunting. Targeting shooting. Silently shooting.

Maybe you can partner with NF and their nx8 and put a 338 blackout specific reticle in it like you did with leupold

 

[redneckbmxer24]

This is cool. I see a 6.5 Creedmoor fix with a 338 Creedmoor barrel in my future.

 

[RickyRodney]

What is going to be optimum barrel length? Less than 16” ??

And partnering for a quality LPV, FFP optic, BDC reticle and adjustable turrets would be outstanding.

12.5”

In many ways it seems to me in a similar fashion of 300/338 win mag, but short action and sub sonic goodness on top of it. Definitely excited to see what comes of this, and how heavy of subs we can get away with. Bigger bullet can do wonders.

 

[hlee]

How is this different than the 338 federal?

 

[buffybuster]

My thoughts too. I guess details to follow.

 

[Kevin Brittingham]

Shorter, more efficient case, allows for long bullets to be loaded and fit into the SR-25 mags. And a subsonic option.

Agreed. Way over 300gr.

Back when I posted this- lots of questions. Listening to the Q & A** Podcast, you've talked about it a bit, and on the Instagram live videos too. I think between that and what's been posted here, I am good to go.

Thanks

 

[usmc45]

Just when your sure you don't need another rifle then something like this comes along. Hopefully they will get the "can" to market first so we can get that ordered and waiting. Very interested to see where this goes.

 

[PlinkIt]

Agreed. Way over 300gr.

Interesting...
Can you give us any insight on what the expected factory configuration will be for the ammo?
Velocities vs weight you guys have seen on the sonic rounds?

1,000fps. 250-0ver300gr. Expanding subs.

What bolt face and action length would this cartridge use? Also what barrel length and twist rate have produced the best results?

 

[littlehendrick]

Above it said a 12.5” barrel. Going with the fact it is a creedmoor case, a 308 bolt face most likely.

That sounds very convenient.

 

[jram]

The barrel life on this should be amazing, just guessing but I would expect well over 12k! If the factory ammo becomes as plentiful as 6mm creedmoor I’ll definately get a barrel spun up.

Any info on the supersonic loads?

250-330gr. expanding subsonic. It's life changing.

 

[jram]

This might be what pushes me to get a supressor, but obviously the current advice of buy a 30 cal can for all your guns wont work. Would a 338 can still attenuate the report of a much smaller caliber, like 6mm and .223?

Yes. I ordered a TBAC 338 Ultra for my magnums but it outperforms the .30 cal Ultra-9 on a 300WM in Ray's testing, and on everything else it's tried on.

 

[jram]

Cool, thanks for sharing that

 

[DiscreetBallistics]

Here's a pic of the expanded subsonic projectile we're working on for the 8.6 Creedmoor. It's pretty close to the 30cal pill we currently offer for 300BLK subsonic. This prototype is 280 grains and expanded at around 800fps.

 

[m6z]

Still interested in this, but I did just buy a .30 Full Nelson.

Will you guys be releasing a .338 can soon?

This ammo looks nuts!! crazy expansion.

 

[GlockandRoll]

I can't wait to get a fix in 8.6. I'll most likely put my CQBSS 1-8 on it, and cant help but wonder if I could fire subs through my .45 Ti-Rant on a 12" bbl? That would be cool and lightAF!

 

[Rootshot]

I've hunted using a 338-06 with 185gr Barnes TTSX bullets at about 2800fps. The devastation on wild boar was extreme. It was as if the pig swallowed a hand grenade (see below).

If you plan on doing range shooting, the recoil without a muzzle device is equally extreme. When my guide wanted to buy the rifle from me, I gladly sold it to him.

I mean, you can do 300 Blk subs through the Ti-Rant 45. So... Por que no los dos?

 

[deersniper]

Any updates on a cartridge specific reticle in a F1 scope?

Pretty much every first focal plane reticle is cartridge specific. That's why we get dope for our specific bullet, twist, and velocity etc

The 300 blk reticle in the Leupold scope works very well.
And good luck remembering your holds for subsonic ammo while doing any kind of practical shooting/hunting.

Well if I were to do that I'd remember or have it written...just like in every stage in every match...

 

[deersniper]

You know in real life you don't get to do a walk through, range find, and data book check before you shoot. Things are. Quicker.

Edit. I think some people don't realize the drop from 50-300 yards of a subsonic cartridge.

If you're a good hunter you've ranged several objects in lines of sight and will be able to get pretty damn close with a scoped rifle, let alone say a slug gun

And if the target is farther and you can't either get closer or get a solid range...well then I couldnt help you

 

[deersniper]

The drop from 50-100 with subs is the same as the drop from 100-400 with supers. So yeah good luck lol

 

[Crazy1323]

Has this round been submitted to SAMMI yet? I have an extra 700 that I’d love to get a barrel spun up in 8.6 creedmoor.

Obviously I’d need dies and brass too

Any idea how fast this would sling a 285gr eld out of a 16” Barrel?

@Kevin Brittingham any update on the TBD twist rate?

 

[Akdodge88]

@Kevin Brittingham any update on the TBD twist rate?

Listened to the latest Q&A$$ podcast and it sounded like it would be a 1:1 or 1:2 twist rate.....

that's really fast...

 

[Hondo1]

That seems crazy fast for super sonic speeds

 

[Dirty D]

That sounds stoooopid fast but I was talking subsonics with Pete Gould and he said that DoD is and has been playing with subsonics and having very good results with very high twist rates that would tear up most bullets at supersonic MV's.

Relistened to the podcast. He starts talking about the 8.6 @34:30. Supers will be between 150-180gr, subs will be 250-350gr. Twist is between 1:1-1:3, not 1:2, still sounds crazy fast.
Sounds like Q and Hornady are doing a lot of r&d so they release all info to SAAMI and manufacturers.
Seems like they are concentrating around a 12.5” barrel. Hopefully 16” barrels will be developed to support those of us that don’t want a pistol or SBR.

 

[Dirty D]

@Kevin Brittingham did Facebook nuke the the_official_q page? I typed in the page in the FB search bar and the page wouldn't come up, Akdodge88's page came up and the_official_q was in the text of his page but a dead link. WTF FB?
