- I Finally get the first shots through my 8.6 blackout build and I go over some rumors I've heard about the 8.6 blackout cartridge... I also cover a problem I had with it. Did I make a mistake building this gun? Will the popularity grow?

Way to showcase the quietness of the round. The indoor range and crappy music really helped
Any gun is quiet without being suppressed 🙄. The video wasn't about how "quiet" the round is. Move along.....
Any reason you opted for such a long barrel with this cartridge?
I had the receiver and handguard set already and didn't know how the pistol brace stuff was going to pan out at the time.
That 1 in 3 twist rate is what allows the projectile to achieve such an efficient transfer of energy to the target as subsonic speeds. Reducing that will make the cartridge less lethal.
It will also mess up the accuracy
You can't mess with that one in three twist and maintain the full functionality of what that round is designed to do. It needs the one in three. The trouble is, most ammunition is not built to withstand the extreme RPM. Of such and extremely fast twist rate. There are small handful manufacturers that build projectiles capable of spinning that fast. This is a 338 caliber. Designed specifically to run subsonic. By the same people who brought you the 300 blackout.
Wowsers!!! Beautiful cerakote!!!
Thanks man, I love the look of it 👍
8.6blk is best suited for subsonic hunting. Bolt action SBR with a suppressor shooting subs is the way to go for 8.6blk. I expect most people who shoot this round supersonic semi-auto will hate it, there are a ton of better options for supersonic. Stop using the handle of your screwdriver as a hammer, lol, right tool for the right job. If you hate your gun you can always just swap the barrel for something else.
300 blk was best suited for a bolt action suppressed sbr as well and look at it now.... Once more manufacturers get on board, it will take all forms just like 300 blk. As far a tools, use what you got in hand 😂😂
That scope would give me a black eye
🤣🤣🤣
Looks like you have a rifle lenth buffer tube on there. That could have something to do with your cycling issues as well as the reason your scope is back so far. Of course the gas block will be your first adjustment step, but buffer tube might need to be adjusted. Also are you putting a can on? I would tune it with the suppressor on because that will definitely change cycling things. I have a PCC that would not cycle with subsonic 9mm. Put a can on and I worked flawlessly every round.
As of right now, no can. It has a carbine length buffer tube spring and buffer. I don't remember the buffer weight off the top of my head, but it is 100% gas block adjustment... Or lack thereof
Ammo price is gonna be a major factor before i ever touch 8.6 Blk. It's a cool caliber for the AR-10 platform though. 👍
Yes, it's not cheap
So besides making a case from 6.5 creedmoor vs.7mm bench rest , is there any difference between 8.6 blk and .338 whisper? Speaking of .338 whisper, talking to ssk industries about what works for it may be a good idea. They have a few decades of experience and J.D. Jones who founded ssk pioneered the whisper family . They are the blk's inspiration and forerunner. .300 whisper has been around since the 1970s. .300 blk IS the .300 whisper plus 1 mm case neck length.
Interesting, I don't have any experience with either of those cartridges to be honest. Might be something to look into. Thanks 👍
The 338 whisper 1, which was abandoned a long time ago, is similar, but it has a shorter case, less capacity and a more 308 style shoulder.
It was replaced by the 338 whisper 2 which had a straight walled case.
8.6 has better capacity for supersonic applications. And it can take bullets 50 gr higher, and uses higher twist.
Try Halworx Ballistics for ammo. I have been running Gorrilla 285's and am not real happy, I am shelving mine for a while. Got a 22cm to play with on the way while waiting for the twist thing to work it's self out
I'm surprised by how many people believe the 8.6 is a hunting round, it was never designed for hunting, it's a wildcat cartridge Q can't find a buyer for. Even if it does get SAAMI approved it's going to be overpriced for people to enjoy, the 1-3 twist prevents it from using economical bullets. The only place for it would be for suppressor using hand loaders.
It is a very controversial round.... Everyone seems to have varying opinions on it. With that said, I wouldn't hesitate to hunt with it.
I want an 8.6 w a 12” barrel for the majority of my hunting.. It better not fart out already.. put real scope w a decent bell on the front,those lv whatever’s are for dumb movies.
👍 that'd be a sweet setup, but I disagree on the lpvo's (if that's what you meant) they are awesome on certain guns
Not safe? Lol what? The projectiles are designed specifically for that twist rate.
The fact they say it MUST be 1:6 when the best shorty 300 blk nowadays are 1:5, even by major military manufacturers like Sig.
What it is is that faxon developed a special way to make high twist button rifling, before they developed that, hoing below 1:6 was a technological hurdle.
Very SUS IMHO.
I'm just relaying what I heard from multiple different sources that design products for the cartridge... With that said there's got to be a hangup somewhere or this thing would have been sammi approved long before now. 🤷
@@ballisticallychallenged I'm not doubting your honesty or your sources. I'm doubting the validity of SAAMI's complaint.
@ravissary79 yea, I guess we'll see
@@ballisticallychallenged see, if they said 1:5 I'd buy that. 1:5 was in the early test range Q tried out and it did well, but I think they were trying to push the twist envelope to harness rotational energy for expanding copper subs... get as much juice into a slug without making it go faster. But aside from that, 1:5 is already very successful with multiple manufacturers and is safe for cartridges that don't even need it as much as 8.6 does. (The max length vs width of 300 blk should never need more twist than 8.6 might need at its max possible length vs width... the 8.6 can load bullets that are much longer but only slightly wider, bullets like this need more twist than wider shorter bullets do, per velocity).
And RPMs on a bullet that's fragile is increased in destructive effect when applied to wider bullets. So despite the 8.6 needing more twist, it's slightly more vulnerable to the destructive effects of centrifugal force. BUT because the bullets have considerably more mass there's more mass to function as a heat sink. And since it's using monolithics, there's no soft lead core to go fluid when spun too hard under enough pressure, and there's no thin skin clinging to the outer edge of that centrifugal force.
I think the danger to jacketed bullets is what SAMMI is afraid of. But in a subsonic application I don't think this is a problem either, as lower velocity keeps bullets below the common 300,000 rpm safety top range. The 300 gr Sierra match king is the 8.6 standard loading, and it's a jacketed hollow point... no problems.
But if you put a 200 gr jacketed soft point in it and push it to supersonic speeds... boom.
So I get it, but that's a reloading problem, not a factory problem.
@@ravissary79My issue with that is when they first designed this cartridge, they specifically said to not use jacketed lead core ammunition because the high twist rate would shred the jacket off. Everyone who buys an 8.6 blackout with the 1:3 twist knows not to use a lead core projectile. Copper solids only. And it’s generally better to use full copper because it retains form in the barrel a lot better than a lead projectile. To me, the notion of arguing about dangers to lead core ammunition when the cartridge was never intended to use lead core ammunition just sounds like taking 10 steps backwards in the wrong direction when there are plenty of case examples of this cartridge being proven safe to work with copper solids out of the 1:3 twist.
Why yo scope so far back? Do you hate yourself? Wanna talk about it?
i'd love to talk about it. I actually don't hate myself, thnks for asking....but the scope is set for eye relief, not asthetics
@@ballisticallychallenged didn't expect a reply lol but fair enough. I was just curious 😁
😂😂 I was going through comments I haven't replied to.
Looks like you're over gassed.
