6X6.8

[Deleted]

Billy let this out so we might as well start the discussion about it. We already have the 243 LBC that shoots the long for caliber bullets very well. The reamer is even set up for VLD style bullets. So I got to thinking what about the shorter bullets.

This is where Billy comes in. He is at work in China without a lot to do so the call goes out. Find all the data about this cartridge you can. I spent the next two days reading every link he found. Believe me there are volumes out there. This case has been mauled badly. Necked up, necked down, shortened, lengthened you name it. After many discussions with Billy, the decision was made. Keep it simple!!!!!!

We will have a standard factory case with the only modification being necked to 6MM. It will be formed and re-loadable with standard Redding 6.8 bushing dies. It should only take 2 bushings to go from 6.8 to 6. Bullets can be seated with any of the short Hornady 6mm seater dies 6 PPC, 6X45 etc.

Brass for this case is every where. Remington, Hornady, Silver State Armory. If SSA brass is used it has the same case capacity as a Lapua 6.5 Grendel.

This should be a lot of fun to play with. Something old thats new.

The key is to make a 30 degree shoulder. QL gives the best performance this way. Look for 6mm DTI it is basically the same thing. others have done the same before.
It makes a very nice round in deed. Should be king with the 87vmaxes.

No 30 degree shoulder on this one. That takes custom dies. It should work with a 23 degree shoulder. That also will keep the cost of dies down, Remember keep it simple. Also don't need any QL. I can do this the old fashion way

Hey I do have stuff to do over here in China , SHOP. Lmao But Ritch is right we been talking about this one for awhile and I finally came back to work So I had time to dig up info lol But we decided to keep it simple like Ritch said and have another offering in 6 mm without the Custom die cost , kind of same deal I am doing with the 6 BRX

I am very interested in this. I had been thinking for some time that a 6.8 necked down to 6mm would be very nice for the lighter 6mm bullets.
Once this project gets rolling will BHW offer barrels?

Yes sir if all goes well with our testing of the first couple barrels , It will be open to the public then which we will all help as much as we can with the info we find out about the test barrels.

6x6.8?

I'm assuming by that denotation its a true 6x43mm? If so, would this be a 6WOA?

I like the idea of it. Been watching lots of folks win competitions with the 6x43. You have SSA and Hornady that offer good small primer brass.

I like the 6x41 just as much though because it will allow for longer 6mm Bergerac to be shot from it. Little compromise for better performance.

If the case mouth is past the ogive at 43, trim it to 41, and it will not hurt a thing.

Keep it simple indeed! I agree. Blow it out, change the shoulder angle? What the ....? Is there a need for a 6mm on this case? Who knows.

For me, it makes a lot of sense as I have tons of SSA brass for my 6.8mm uses. Nice cases, good size for AR bolts, efficient. I have plenty of magazines. Here in the Black Hills area PDs can get way out there and of course the wind never blows. I would embrace a 6mm for the better BC using one of the many available sensibly priced bullets.

Through the years of my shooting and reloading of magnums and/or maximum loads always just because, proved it just isn't worth it. Extremely short case life, a whole pile of propellant, and not always best accuracy with a given firearm; and, the accerated wear and tear on the firearm.

The good strong brass, small rifle primers, modest powder charges (probably the same one used for my .223, 6.8 loads) for good theorectical velocity, huge selection of very fine bullets, mild recoil seems to make sense to me.

I thought I would build a 6 x 45 but stopped because I feel the case capacity is lacking for what I want it to do. Teased by the WOA or DTI offerings at one time, I knew I wanted a tad more. But not much more as I have no intention of using it for big game.

The LBC cartridges would do the job but at greater cost. So I'm cheap. Give me a 6 x 43 mm or what ever it would be called.

So what am I getting at? Call it cheap, frugal, or logical. KISMIF? Build it already. It doesn't need a protracted development.

[GLSHOOTER]

I don't know. A 6 MM shooting light bullets very fast out of a no-turn wildcat cartridge that I can buy cheap brass for? It will be a tough one to decide on but since 6.8 bolts are available all over th place I do believe I see one of these bad boys in my future. If it has the same case capacity as the Lapua Grendel stuff then it should be a real hoot.

I know that I am in the market for a 1000 yard potential gun and perhaps Billy's design will do that. I would like to be able to shoot those high BC bullets and stay supersonic at the target. I bet we all find out quick!! Now if the Magnum Uppers come out then I see that being a possisibility since we could run the pressures right up to the top and have plenty of safety margin with the bolt/extension combo tat will be used.

Thanks for the basic information on this one.

This is a true 6X43mm
This is not a 6 WOA. The woa has a 30 degree shoulder as far as I can tell. If I am wrong let me know.
I will agree with Paul, if you have a need to shoot the long bullets just trim the case. It can still be fired in the same chamber.
Personally if I were going to shoot the long bullets the LBC is a much better platform than the shortened 6.8 case. This case is really built for short bullets. ( meaning 87 grains or less ) Anything longer than that you start to loose case capacity by seating the bullets to mag length.

[Deleted]

Greg you in luck. I talk to Dave about my build on the BRX and it is being done for the heavier bullets 80 s up to 107 and with the HP that case puts out you will have what you looking for. On the 6x6.8 ritch had Dave build this reamer for the lighter stuff but like Paul said we can make it work in heavier bullets if need be. But you guys know me I need a couple of each . But I do think each has there place and need , I love my 6x45's and the 243 LBC is out right wicked on anything it touches and simple to load for with $35 dies , and this 6x6.8 and 6 BRX will also have places for a easier bolt to find in 6.8 also going to be easy to get dies and brass for, and the BRX will have the cheap dies but the extra cost for Super bolts and Ext and higher brass cost , buts that's the trade off on the BRX for getting that type of HP. And just think when that Mag upper comes out we already have ideas floating around our busy minds

[GLSHOOTER]

Billy and Ritch thanks to both of you for using some common sense on these. Us old retired guys aren't as flush as we use to be!!

Your new ideas have actually got my juices flowing again. I have to say that BHW, Carl and you guys have restored my inquisitive mind and make me want to go out and compete even more.

I'll see your 1000, and raise you 500 yards, or more.

Yep, Billy's 6BRX will do that. I have not run the numbers, but it will be supersonic close to a mile.

The magnum upper will be awesome, but the AR Performance bolt and extension should handle the pressures just fine.

The 243 LBC exceeds your 1000 yard supersonic mark by several hundred yards.

The 6 SPC probably will not do a 1000 yards supersonic, long bullets will eat too much case capacity, but that is not what Ritch and Billy designed it for.

Thanks for doing the numbers Paul. I was to lazy to punch 'em up!! I figured the 6 SPC would not do it so the BRX may well get a run as will the 264 LBC. It will depend on what barrels are floating around..Do barrels float?
