Home Forums Hunting & Shooting Hunting Rifles 6mm ARC - Hornady's New Cartridge

https://news.barrett.net/2020/06/03/barrett-announces-shipment-of-6mm-arc-rifles-to-us-dod/

Barrett is getting ~2,630+ fps with factory 108s in 18" barrels. Saw other pictures on The Hide where a guy averaged 2,698 fps with the same ammo in a 20". That's not too bad on the velocity loss, and plenty useable.

I like shooting long range, and I like shooting ARs at long range. I like my Creedmoors and my 6.5G, but the Creedmoor doesn't fit in an AR-15 and real world velocities with my 6.5 Grendel are about 200 fps slower than the ARC, with lower BC bullets.

My only questions are 18" or 20"? Medium or heavy profile? LR/hunting combo or heavy LR bench rig? Once I get the answers to those figured out, I'll be ordering a barrel for sure.

I think it would be a fine choice for the 223 length Barrett Fieldcraft that we are not going to get.

I think this is more for the prs crowd.. not the hunting crowd.. which nothing wrong with that.. this also can be used in the NRA AR tactical Mid-range prone class. I will definitely put one together for the purpose of shooting AR tactical class

What's the military using it for exactly, besides whacking bad guys?

Quick run of numbers but I don’t see how a 1-10 twist 243 beats this cartridge.

108’s for the win!

That ballistic advantage 20” dmr profile looks like a good bet. Should be a cvnt hair over 2.5 pounds.

It looks to be a small quantity T & E contract. They want to see what it can do and how well the grunts like it.

Looks good to me.

Hornady is in business to make money. Anyone involved in sales knows that it is a "numbers game". If you ain't pitching, you ain't selling. If you ain't selling, you ain't making money. And after you sell so much of one thing, you need to be pitching something new... Same reason there are eighty eleven flavors of Italian salad dressing on the grocery shelf...

I have no personal interest in the 6mmARC just like I have no personal interest in the 6.5 Creedmoor. However, I am glad that they are selling because that means that the ammunition and firearms manufacturers are making money. Which increases the likelihood they will still be around to produce the things that I am personally interested in...

Thanks. Will be interesting to see where it goes.



Question, for the hell of it.

How could you get more out of the AR15 than this? More is whatever you want. I like accuracy, range, lethality...

Bingo! Never could understand all the flack anything new catches here. It's all good, and almost everything is interesting to me even if I don't have any use for it right then.

Agreed, a healthy firearms/ammo industry is good for us! '

Now house it in a micro bolt action (in stainless) and they will sell. Bonus points for a trim stock.

Was thinking one in SS with a youth stock would be a killer little rifle for wife/kids. 103s for play and 95 lrx to take care of business.

I'll take one in an ar please and another necked to 22 with about a 6.5 twist for 88s.

I'm going to wait for reports on bolt durability.

I’m glad there appears to be a factory 6mm for the AR15 platform, set up for success. As for getting ‘more’ from the platform, Hornady had their reasons, that won’t all make sense to some.....there’s an argument that a different case, that allowed a different bolt head thickness/higher pressure, would seem to have given more versatility or potential or efficiency in shorter barrels. However, maybe (just maybe) Hornady figured out what (they believe) is the maximum potential there for a 6mm in the AR mag length, and that the lower pressure option was better from a factory sales standpoint? No idea...just trying to see it from outside this bubble. As long as the pressure is kept down, the bolts aren’t likely to be an issue, and it’s a win for the gun and shooting it. IF I was doing much with an AR15 past 300, for hunting use, it would be the best factory option I’ve seen.....however, it can also be the longer range precision package that beats all else, for performance vs size and weight. At 18” and under, and normal deer/hog ranges, there’s other players, but it may work there just fine, also. I haven’t looked into that 108 vs the 103 on game, but the 140/147 6.5 ELDM works very good on deer, IME....at medium velocities.

Yes. Where I’m at I don’t even have to have SS but would prefer it.

Yeah....that, too....I would be in for a mini-action, lightweight, hunting gun, too.

Howa is on Hornady's list of industry partners in the cartridge rollout, so I assume a mini chambered in the ARC will be forthcoming at some point.

Not just for the wife and kids. This is about what I have been looking for for a woods deer rifle. Was going to build a 6x45 or a 6mm br, but this will be better if it has good factory support.
