Bratrifles sells the mags, but it will be alot cheaper to just buy the single stack follows for standard mags.

Thanks for the information. Since I joined this forum you guys have gotten me very interested in alternative calibers for the ar15 platform. I just finished my AR in 6x45. Next is a 243LBC. Then a 6.8 and a 6 BRX and then...............my wife is going to kill me.

I hear you on the wifes mine said I can't talk to Ritch anymore ;D

Wow! I'm hoping this stays simple where the common sense does rule. Like Greg, being retired now, gotta watch my toy budget. Can't build them all and this would be my choice over the 6 x 45.

It would be nice to be able to clean out my shop and end up with a very nice upper and repurpose some bench components.

Please keep it simple and sane and soon.

I load the 6x45 and have perfected my loads to move with the same flight path (within 2.5") as the M855 using 90g FMJBT and 100g SBT bullets out of a 1:9 twist 20" 6x45 barrel. That way, I can use my ACOG with 5.56 drop compensation in the same manner while retaining plenty of energy and stabilization for those lengthy shots out to 600 yards.

My goal is to build a 6mm/6.8 in a 16" barrel and fine tune it to the same velocities because I now have the extra case capacity available to make up for the loss of velocity in a shortened barrel.

I got my hands on a set of 6mm WOA dies and got a few dummy rounds loaded. I currently cannot find anyone to cut me a 16" 6mm WOA barrel since WOA is not currently taking custom orders. What is the difference in the chamber specs from the 6mm WOA and the 6mm/6.8SPC? I dont want to utilize these dies if the dimensions are different enough to wear the hell out of my brass or chamber.

I have heard plenty of good reviews of BHW products but havent given them a shot yet. This seems to be the right direction to go since they are expecting to cut some of these 6mm/6.8 barrels pretty soon. Thanks.

The WOA has a 30 degree shoulder vs a 23 for the 6X6.8. I believe your dies will have issues if you wanted to load the one Ritch is doing. Performance wise I doubt if there would be much difference but you can buy the 6.8 bushing dies and then load 6.8 or 6X6.8 with only a bushing swap and a 6 MM Hornady seater will handle the rest. Very cheap compared to a set of true WOA dies.

Well, I already have the Forster 6mm WOA dies, so I may have shot myself in the foot. I dont mind waiting around for a barrel, I have played that game on several occasions.

I've heard that WOA will not be doing anything special for quite a while on some other boards. Maybe you could turn those dies and go with the regular shoulder 6X6.8 anyway.

Mike Mirili explained how he didn't see any substantial results until he used the 30 degree angle with the 6mm DTI which is nothing but the 6.8 case necked down and pushed to a 30 degree. Very simple, very effective. The results he got with both the 6mm and the .25 are consistent with what QL says.

Actually I made an error as the WOA also moves the shoulder back. On the DTI it remains the same as the 6.8. HOWEVER the big caveat is going to be that 30 degree issue. The DTI and WOA will have to be fire formed and the dies are, as was pointed out, at a greater expense.

I'm not smart enough to run a Quick-load program and I guess I tend to want to pull a trigger rather than rely on a program and hitting enter.

I'll go spend my $$'s where I think I'll get good value and right now BHW , thanks to Ritch , is fixing to supply me with GOOD VALUE!!

No need for expensive CH4D, redding, etc... custom dies. You can simply build a sleeve for the 6mm BR and have it in place by a cap with the same die thread at the bottom and to match the 6.8 chamber improved to 30 degree. All that is needed is a nice lathe.

As I said, the shoulder of the DTI is a 30 degree. The shoulder of the 6.8 is 23degree.

From DTechs website...
"6 mm DTI ( 6 mm Dtech Improved, 6.8 SPC case necked down, and a 30* shoulder)"... www.dtechsuperstore.com/new_altcal.htm

He ran into those issues and eventually followed QL direction. Call to Mike. He is a great guy.

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.

After extensive testing,we have found performance is not effected by a 23 degree shoulder. It will in fact run with, if not out run similar wildcat cartridges. It is NOT a DTI or a WOA!!! Both of these cartridges require fire forming. The 6X68 does not

Performance is better than expected with light weight bullets. Velocities of 3650-3700 are being achieved, using 24 inch barrels.
Mid weight bullets are running faster than expected as well. The Hornady 75 gr Vmax at 3275 FPS from a 22 inch barrel is nothing to sneeze at.
We have been pushing 87 gr bullets over 3000 FPS with boring regularity.

All in all this cartridge has far exceeded all expectations. Its fast, easy to load for and components are easy to acquire. I can see myself shooting the 6X68 for a long time to come.

Got my new 6x6.8 barrel on 1/31/13. Shots 1,2,&3 were to get it on paper. Shots 4,5,& 6 you could cover with your thumb. Shot about 30-35 rounds just playing. Then tested it on my dinger @ 365 yds. 4 out of 5 shots were in the 1 1/2 group, the one that went astray was my fault.

Thanks BHW gang, I think I have a shooter.

By the way, that was the 22 inch light barrel that you made. Nice job.
