I figured id get a cheap barrel from Tacticalinc.com for $99 bucks since the Daniel Defence barrel i wanted is not to be found anywhere...

Got to lookin over the email to see if i could find a tracking number and noticed it said 6.8 instead of 5.56.. HUM..
So im prolly fixin to venture into the 6.8 world.
Hey atleast the 7.62 suppressor will fit on it

Just what i need is another caliber....

 

[nonnieselman]

Just got off the phone with Tacticalinc and the lady told me she would send out a call tag and swap it out for a 5.56.. I ask her if i could try it and go from there..
She said that would be fine and if it doesnt meet my expactatoins then she would send the call tag out then and send me out a 5.56 barrel no charge.


I already have 6.8 brass, and dies in my cart on Midway

 

[mattblake]

So they did mess up huh? Only you nonnie.

 

[nonnieselman]

Yea... now i gotta find a 6.8 Bolt...
Might just end up building another AR

 

[M1GarandFan]

:lol4: Sounds like a good excuse to me :lol4:

 

[mattblake]

Yep sounds like a new build to me

 

[captain-03]

What the heck!! ... it is just 1 more caliber to support ... :affraid:

 

[jbpmidas]

Is the 6.8 barrel normally $99?

 

[nonnieselman]

Na its bout $130 or 140 i think. I finally got the burnt out 5.56 barrel off the receiver and of course like most other things it drew blood. But i got that ammo sucker off. Cleaned everything up and got the 6.8 barrel on. Now i gotta get a bolt, brass, dies, hand guards, gas block, atleast one mag, and a flashhider.
Thinkin bout takin the muller scope off my 308 and using it on there. Good thing i got some 90hp, 110 match, and 115 smk stocked up from my 270.
Gonna have another deer slayer goin soon.
Will update when she is slinging lead.

The tacticalinc.com site says this barrel is a 6.8 SPC chamber. This will limit how hot you can load your ammo. You can ream the chamber to SPC II specification, and that will let you load hotter. (Reaming to SPC II just increases the jump to the lands a tiny bit -- it doesn't make any other changes to the chamber.) However, the 1:10 twist will also contribute to higher pressures. A 1:11 or 1:12 would let you load a good bit hotter.

The tacticalinc.com web site doesn't say what length the gas system is, but FWIW best results on the forums for 16" barrels are from the mid-length gas systems.

BTW, I'm not trying to rain on your parade. Just wanted to let you know some of the limitations of that barrel.

I would like to have a 6.8 or 6.5 with 22" or 24" barrel.

I been reading on 68forum so im learning this stuff slow..
If i dont like it, ill get them to send me a 5.56 barrel

Gas system is Carbine length..

In 6.8 you don't gain much velocity with barrels beyond 16 inches. Going from 16 to 20 inches you gain about 100 fps best case (i.e. 25 fps per inch added). The powder is pretty much all burned up by the time the bullet gets 20 inches down the barrel. I don't think inches beyond 20 would add much velocity at all. None of that's applicable to the 6.5 though. I believe I read that it benefits nicely in velocity if you go from 20 to 24 inches.

Yeah, you may end up loving that barrel. The price you found is incredible so you might as well give it a try. If you decide to keep it, it's probably worth it to get the chamber reamed, or ream it yourself. You can send it to ADCO or I think Wilson Combat for that, or buy a reamer yourself and sell it on the boards for probably 80-90% of the original cost.

With the carbine length, just keep an eye out for signs of rough/hard extraction. It might be a little tough on the brass and/or extractor, but those can be changed easily enough.

One of the things the 1:10 twist is good for -- heavier bullets over 130 grains. The 1:11 and slower twists will stabilize the 130 grainers just fine. But if you want to shoot 150's, then the 1:10 twist will be better. The people shooting 150's are shooting hogs at close range, or trying to stay subsonic.

 

[nonnieselman]

I have some 150gr Bergers.. but they are gonna be wayyy too long..

As long as i will do 1moa or 1.5moa ill be happy..

Thanks for all that info.. saves me alot of time researching.

 

[smoffett]

Yeah, long bullets are tough on the 6.8. The case is pretty small relative to the size of the bullet it's pushing. Most folks who are loading in the normal range (i.e. 90-130 grainers) are at or near compressed loads once they've worked up to maximum.

You should easily get 1.5 MOA. With your 1:10 barrel I'd probably start with the 115 SMK. Lots of good results on the forums with those. Let us know how it goes.

FWIW, the Hornady VMax are notorious for being inaccurate in the 6.8. Nobody seems to really know why, and YMMV. I just notice a lot of new 6.8 owners on the forums who start with the VMax because it always worked well in their other guns. So they start with VMax in their 6.8 and think the rifle's no good. They switch to another bullet and voila, problem solved.

Have you got your mags yet? Reason I ask is that the different brands are pretty different in how long you can load. PRI allow the longest COAL (about 2.3 inches) but they're pricey. You'll want to load as long as you can that will still allow the bullets to fit in your mags. It helps reduce pressure and tends to make the 6.8 more accurate as well.

Yea i was gonna break the barrel in with some 110gr Vmax since they really didnt do great in my 270 and i have no use for them..
i have some 115 and 135gr SMKs im gonna use for a hunting/target load.

I was looking at the Cproducts 5 and 10rd mags..



BTW,,, that barrel nut was extremely tight on the Delton Upper.. Took forever to get it off..

All the bolts about the same for the accuracy standpoint?

Here's a really good review of all the 6.8 mag options right now. I like the C-Products mags fine, and the price is right. The first 6 I bought allow a COAL of 2.297 inches. (The PRI mags let you load out to 2.3 to 2.305 inches, the longest you can get, but they're pricey at $40 each.) However, I recently bought a few more C-products and they don't let me load as long. The way they spot welded the front edge makes the metal project inside the mag a little bit. (See pictures in that review I linked to above.) But my handloads are already loaded out to 2.297, so I'm gonna have to sell these shorter mags. I've got 4 of the 25-rounders like this. Wanna buy 'em? I'd sell all 4 for $30 shipped. BTW the 5 round C-products mag is the same as the 10-rounder, but with a different spring and a plug so it will only hold 5. Might as well buy the 10-rounders if you're going this route.

You know I haven't heard a single report from anybody who replaced their bolt and said accuracy got worse or improved. I haven't heard of anybody breaking a 6.8 bolt either. I'm thinking a bolt is a bolt here. However, if you just want the toughest bolt out there, take a look at this one. Bigger construction and tougher materials. More info here about a third of the way down the page. By all accounts he makes fantastic weapons, so this bolt should be GTG.

HTH.

 

[smoffett]

BTW they are doing a group buy on the C-products mags over at the 68forums. $8.25 per mag plus shipping. This is extremely good pricing. Here's the link...

I know this is an Old thread... but I've heard bad things about the 6.8 cproducts mags... I have two PRI mags... and they are expensive. I've also heard you can slightly increas the OAL of the cartridge in specii chambers to increase accuracy but the slight length increase they will not fit in cproduct mags..
