[Scotts556]

Im working on getting my big Ford Sold, when it happens I'm looking to buy a 6mm AR upper. Whats some pros and cons of this round??? I just wanna shoot some informal long range and shoot some local matches round here. Max I shoot is bout 800 yards. Sorry if this is a lil vague, Been awhile since I have last Posted.

Thanks

Re: 6mm AR, need some imput.

what would you like to know ?
cant realy pro and con for ya since i only have 1 in the area.
but I like my Oly Arms .243WSSM . dont think its a 800 yd gun but it could be with the right know how.

Re: 6mm AR, need some imput.

Go for the 6mm AR Turbo Improved. The only con is you have neck size 6.5 Grendel brass. Otherwise it's a fantastically accurate cartridge and well worth the money.

I was really considering one of these, 6mmAR, but decided on a 6.5BR from AR Performance. Grendal brass is pretty pricey but I'd imagine you could neck down some 7.62x39 brass, not really sure if it will work though.

How's your 6.5 BR running? I know AR15Performance also offer the 6.5 BRX.

General rundown on the round. Performance?? Max effective range? How easy is it to tune a good load? How good is it a knockin over steel? From what little i have read it sounds to be a good round. Not some super performance round but something good at punching paper,and thats all I really need.

Re: 6mm AR, need some imput.

Ill give a thumbs up for Robert Whitely at 6mmAR..

I bought a .22ar upper from him last year with all the bells and whistles. and man that thing shoots and feeds awsome. not a single problem with it from day one.

I would highly recommend wwww.6mmar.com

 

[jdel]

Re: 6mm AR, need some imput.

Havn't got it yet. but when I get it up and running I'll post up about it. It's supposed to have an edge on the .264 so I opted for one.

Re: 6mm AR, need some imput.

S5:
Don't know if he is still building them but WOA built me a 6mmWOA which uses the 6.8spc case. I use it for hunting but if I recall correctly it was close to the 6mmar. Also as a 6.5 Grendal owner I can tell you 6.8 brass is easier to acquire.

I have A 25 WSSM (same case as the 243 wssm) and also a 6mm AR Turbo 40. I like them both, but for long range work I would go to the Turbo 40.

The shorter Grendel case allows for use of longer VLD bullets that will still fit a standard magazine. The Turbo 40 is a very flexible cartridge. I have tried at least a dozen different bullets with the turbo 40 from 70gr to 107gr and it shoots them all well with very little tuning. Favorite loads will shoot sub 1/2 moa with ease.

The wssm is very accurate (but not quite as accurate as the turbo 40), but much pickier on loads. The heavy wssm brass can be a pain in the ass to work with. The turbo 40 is very easy to load for and even the fire-forming loads are extremely accurate. It is also more economical to shoot since it uses less than half as much powder as the wssm. This will also mean much better barrel life. You also have less recoil and muzzle blast.

With VLD bullets, 800 yds with the turbo 40 is no problem.

Lakeway, thanks for the great info. I'm flirting with the idea of the 6MM AR 40T. Did you do much comparison with the standard 6mmAR? Were you able to go to Doylestown and shoot one before purchasing? Any downside at all to the cartridge and the upper?

I am a handloader so have no concerns about the availability of ammunition.

I am a longtime bolt gun shooter and recently picked up a stock Bushmaster. I put together some handloads for that and have been frustrated with the 1.5 moa groups I'm shooting. Initially I leaned towards getting a WOA .223 upper as an upgrade but started reading up on the 6.5 Grendels and found them very compelling. Boning up on that led me to the 6mmARs and now I'm not sure what to do!

Re: 6mm AR, need some imput.

You will love either. Set it up with the right riser / rings, butt, trigger and you'll be happy always.

I shoot 6Rat, a slight variation of the general theme. These rounds make fabulous AR15's. Holliger, Wells, or Whitley build em and they're all fine uppers.

Bustn here on the hide builds 6br/brx and I think he too really knows his stuff. From what I can see on his site I'm impressed with his enhanced bolt for this cartridge.

105AMAX and 87VMAX are super accurate with little or no load development in my experience with the Rat.

From the Turbo 40 a 108 gr Berger is still travelling supersonic at 1400 yds. It's a great long range round.

I agree! Sometimes it amazes me how accurate and capable the tiny cartridge is.

LOL,My friends are always giving me a hard time that the cases are only half grown up

but it's hard to argue with 105 Amax's going 2915 fps and producing .3" groups about half of the time.

Re: 6mm AR, need some imput.

Guys, thanks so much for your informative and prompt responses, I think I'm just about sold on the Turbo Improved. In your opinions, is there ANY reason why someone would go with the Grendel over the AR T Improved? I'm on the verge of calling Whitley today. Thanks in advance. Tom

I shoot the same round as Casey and we have shared some load info with similar results. Built my own uppper using WOA barrel and bolt, used a 22" Krieger 1 in 7.5 twist profiled to save some weight. Mine likes the 87 gr. V-max and the 105 A-max best with the 108 Bergers performing well also. Have shot several DMR type matches with the rifle and it excels at 600 yd. plus. Shoot the 87's out to 400 than switch to the 105's for distance. Recoil is a not an issue with a decent brake, makes a small format AR into a formidable rifle.

 

[TDaly25]

Re: 6mm AR, need some imput.

Thanks Bronco. I'm totally jazzed and getting ready to call Whitley right now

 

[TDaly25]

Re: 6mm AR, need some imput.

Woo Hoo, I'm pumped. Just got off the phone with Robert Whitley and purchased the Turbo 40 Improved he had in stock. Test fire tomorrow and pick it up Friday!!! I know what I'll be doing all weekend

Thanks all, for your great info. Cant wait to post the first range report!!!

 

[Blackhawk95]

Re: 6mm AR, need some imput.

You will like Roberts products. My .22AR from him has been flawless. and he only uses top quality parts.

Good luck on you new upper

 

[Erud]

Re: 6mm AR, need some imput.

Whitley's 6T40 is a sweet little round. The fire form load in mine(28.5 Re-15, 95 SMK, Wolf SR mag primer) is extremely accurate and I just use it for 200 and 300 yard lines. For 600 I am shooting a 105 A-Max with 30.5 of Re-15. Both are great and fire-forming is really no trouble when the load is accurate and useful. You'll like it. Make sure to get your brass from robert also as he's a good bit cheaper than anywhere else I've seen.

Good luck,
Erik

Re: 6mm AR, need some imput.

You could also take a look at accurateandreliablerifle.com for this cartridge that is called the 6mm RAT. Same thing different maker with less cost.

 

[trilogymac]

Re: 6mm AR, need some imput.

I have 2 of the 6mmAR's. One heavy barrel and one light for hunting. Shoot 105amax in both. Next to zero load development needed. I would do it again in a minute. Make the call.
Below is a pic of my 10yr old and the 6mmAR after his 1st group at 600.

Hope this helps

This may be a little old but to tell you the truth it's a really good round. Just really, really spendy. If you think a 6, 6.5 or 6.5 BRX is spendy then a 6mm AR is more. Also, +1 for AR 15 performance. They have the best bolt design for the BR/BRX cases I've seen.

I know someone mentioned the .243 WSSM in a previous post. Here's the problem. The case produces more power, but you can't fit a super-high BC bullet in it and also in an AR-15. The biggest case capacity I know of that you can do that is the 6mm BRX. And as noted AR-15 Performance has an improved strength bolt for that. But, if you are going that route, I think the 6.5 BRX is about the best of all choices.

So, out to 600 yds. for sure the .243 WSSM will spank any AR or BR/BRX. But, out where high BC takes over, you'll eventually want the slightly smaller case.

Edit:

If you are looking to save money, I use a lot of 7.62x39 for my cases for the 6.5 Grendel. That may make a big difference in your choice of caliber. Just remember that it's a large rifle primer case not a small primer. That saves me $40 per 100. And what I did was buy a couple 7.62x39 magazines to feed the fire-forming rounds. They shoot pretty accurately too. I use AA2015 and 85 gr. Sierra varminters. I know many won't believe this but even during fire-forming they will hold sub-MOA. Most of mine shoot sub .5 MOA.

I decided on the 40 improved over the regular 6mm AR simply because I wanted a little more velocity for hunting. I did not shoot either before making my decision to buy. I based my decision on Robert's excellent reputation and a good deal of positive feedback similar to what you see in this thread. If there are any downsides to this cartridge or upper, I have yet to find them. I have some nice ARs, but this one is my favorite.

There have been some other alternative cartridges mentioned in this thread, but I have no experience with them. The people on this forum are pretty knowledgeable, so if they say they are good, they probably are. It's easy to go into "analysis paralysis" when there are so many good choices, but if you go with the Turbo 40, you won't be disappointed.

Thanks for the mention but, DPMS and MB has stopped making 7.62x39 extractors used in the BR bolts so we are not making any BR bolts until they start making 7.62x39 extractors or we can redesign the bolts to work with 5.56 extractors. We have sold out of BR bolts for now and our machines are busy running other parts so it could be a while before we get back to them.

Some FYI's....Just before I ordered my 6mmART40 I had a 243wssm upper and sold it.A couple other things I discovered that I didn't like about the 243wssm were.

Poor brass quality,that's putting it lightly BTW.reliability problems,a lot of work to find a good load.

Single stack feeding so lower capacity.

Hard on steel(pock marks on AR400) out to 300Y with 75-87 grain bullets.

Re: 6mm AR, need some imput.

I also have both the 243 WSSM and the 6mm RAT and a 6mm SPC AR15. The 243 WSSM is awesome for killing stuff, but the brass sux bad and the caliber can be quite finicky in the AR platform.

</div></div>

I'll agree with both of you. I shoot a 25 WSSM and the same thing happened there. New brass quality went to crap in about '07. Annealing the old stuff is difficult as the case is so short, by the time you get the neck red, too much heat has already made it's way to the case head. Gotta stand 'em in water.

But, the 4-5 loads I got when Winchester had good QC on the brass...were really good. But, I put it on the back burner too as a comp round because by the end of the competition year I had to lay the rifle on it's side and slap the action open after every round.

I also feel that the case is overwidth in proportion to the neck. Moreso with the .243 and .223. Too much lateral movement of plasma for the case to allow pressure <span style="color: #3333FF">{to flow down the barrel}</span>. Just my opinion. It's obvious though as people are having success with these necked up to 7mm, .30, and .338. But, that's a tangent.
As far as the 6mm's go, The best brass, case length, capacity and power all lean towards the 6mm BRX.
