They're variant's out there, however the 6mm WOA is based off the 6.8 SPC - I run a lubed 6.8 SPC case through my Redding 6mm WOA die, and I have 6mm WOA - Again, the 6mm WOA is a 6.8 SPC case necked down to a 6mm with a 30 degree shoulder. The real plus side to the 6mm WOA IMHO is it takes standard 6.8 SPC magazines. Edit: Maybe the title should changed to 6mm WOA, but either way it's a 6mm and it's a AR

I like the handguard. Who makes it? John | 6.5 Grendel: World's Best Combat Cartridge | |

Great rifle! Do you have a link to more info? In your opinion what are the advantages of the 6mm WOA when compared to the 6.8 SPC or the 6.5 grendel? I have been leaning towards buying a Grendel for target/hunting but have been a little discouraged by the long waiting times and lack of availability of all things Grendel. Thanks. |
John, www.whiteoakarmament.com/matchparts.htm Scroll down about 1/2 way. |

I was shooting with fellow member Ardvark one day and he was shooting one these uppers that Holliger had just made for him. I think he was running Berger 105s, but it has been a while. Anyway, I was shooting a Grendel and the 6-SPC WOA was shooing every bit as good as my rig was. We were shooting at 200 yards, fwiw. There are so many good bullets in 6mm between 80 and 115 that it should be pretty easy to find one that will shoot well with the cartridge. Mind if I ask what did this run you, and does WOA stock the dies? |
The cost really depends on what you want - This upper had been a 6.8 SPC that I had John build for me last year. It was ok, but wasn't very satisfied with the 6.8 SPC in general (the upper was great, the cartridge/round wasn't for me), so I sent the whole upper back to John to do his magic on it with the 6mm WOA. We kept the upper receiver, barrel extension, bolt & carrier (meaning no charge for me on these parts). John provided the barrel, gas block/tube, float tube (forearm), labor and shipping was right at 4'insh - And WOA does have the dies in stock, plus everything else you could possibly need (mags, sometimes new brass, etc.). WOA is number one in product and service in my book. I've got 4 WOA uppers - One service rifle, one 3 gun SPR'ish, one light varmint 6mm WOA, and now this full size 6mm WOA - Yes, I have BRD with WOA uppers also.  Someone asked about the twist? The twist is 1/8.5 |

CK, what didn't you like about the 6.8? I would think a necked down 6.8 in 6mm or .250 would make for a flatter shooting, better overall hunting cartridge. My trouble is I'm wanting something with a 16" barrel. For a 16" barrel the 6.8 might be the best option. I emailed White Oak and John Holliger said the 6mm WOA hasn't been tried with a 16" barrel yet. |

CK, I knew I'd read this some where. Coming from John I'm going to assume this was designed to shoot 105s. A 6.8 case is too long to shoot 105s without trimming. And Bergers are usually finicky about jump so tell me have you tried the 105s and how do they shoot? And did you have to shorten the case? Thanks, Harrison Also what blank did he use? He talked me into a Wilson last time and he was right they do shoot. |
It will shoot 105's though I have not shot any yet and from what I've seen others shoot is single loading only. There's two of us in town that have 6mm WOA's. The heaviest I've shot were some 100 gr. SPHunters in magazine length and that was out of my 20 inch 6mm WOA and was very accurate. No shorten of the case. My new 24 inch 6mm WOA and the 20 inch WOA both have Wilson blanks. |

I've had a 26" 6MM WOA for a couple of years. I was going to transition from shooting Service Rifle in High Power to a space gun, so Holliger cut a barrel for me, a 1/8 PacNor. In experimenting, for short line bullets, I settled on the 90 Berger loaded mag length. I can run it 2900ish without strain out of the 26" barrel. The 85 SIerra and 87 Hornaday shot fine, but their BC is so bad, they offer no ballisitc advantage over a 77 SMK out of a .223. For 600, I have mainly shot 107 SMKs. They can comfotably run at 2650. John's experiment was to get 6 BR velocities out of an AR platform, which he did admirably with the 6 MM WOA. I was too cheap to buy the specialty mags for the 6.8, so I took standard 20 rd GI mags from 44mag.com. I removed the riveted in liner that keeps the floorplate of the mag latched, and installed Magpull followers, springs and floorplates. They feed the 6MM WOA fine! It's an interesting, flexible cartridge with good performance, equalling the 6 BR. Since it's from Holliger, the work is also flawless! I just haven't given up on Service Rifle yet to shoot a space gun. |

I have a 6.8 from John and it shoots great. With 115 SMKs I get a consistant .5 moa. I'm trying to talk Berger into making some 110-118gr bullets with a better BC. I know he's one of the best AR smiths in the country. He talked me into the Wilson and I think he was saying there's no need to spend alot of extra money on blanks when he's the one chambering it. Now I'm interested in a 6mm. I think Berger is or was making 3 different 105s. I've heard the old VLD is too long but what about the new 105BT? Have either of you shot it yet? Can you load it to mag length? |
