Hornady was to announce this one at the NRA show but with COVID that got changed. News announcement today

Interesting....a 2k fps 108 grain cartridge just doesn't excite me for some reason. I wonder what the 87 grain bullets will be able to be pushed at?

The case is the 6mmAR with the body shortened .03 inches so real close to the velocities people are getting with it.

Factory results show 2750 fps with a 108 grain bullet in 24" AR barrel. It's like a 6mm Grendel. I love it!

I’m in for this one - I’ve tried 6mmAR and 243 lbc and contemplated 6mm Predator

All three of those the dies are either not made or 130.00 plus.

I’m in for the simple fact that I can buy reloading supplies for normal pricing and load up some 90 grain bonded bullets for terrorizing hogs.

Just need the supply chain to catch up to Hornady’s marketing team ....

I misread the chart...that 2k fps number is at 500y.

I've got zero use for a 24" AR barrel but I'll be watching what it'll do in a sub 20" barrel.

Paging Mr. Wilson - how far out is a Wilson Combat 6mm ARC barrel ?

They didn't claim it was an AR, just 24". Would be interesting to know. Also, almost nobody is running a 24" AR.

Real world, it's going to be 2500-2550 out of a 16" barrel, which still makes it a sub-300yd deer gun (1000 ft/lb). But low recoil, AR platform, great downrange ballistics, and factory support are great things. Could be another winner for Hornady.

According to Beckstrand 2698fps from a Seekins 20" so maybe 2640fps from a 16", should be north of 2600fps anyway

I think they have a winner with this one. I like the 6mm projectiles in the AR-15.

Midsouth already has components, Hornady was going to release this at the NRA convention but with it canceled they delayed it, giving time for getting stuff in the supply chain. More videos in the link below

We should be shipping them by the end of June, all of our R&D testing is done and we have the first production run in process. Prices will be the same as a comparable 6.5G or 6.8SPC bbl

Hell yeah!

I would like to know what 16” would do

Which mags?

Grendel Mags, if you have a 6.5 Grendel AR just swap the barrel and you have a 6mmARC all other components are the same.

We will be making the following, all threaded 5/8-24:

16" Ranger .675/.750/.650
18" Recon .800/.750/.740
20" Recon .800/.750/.740
20" Super Sniper .925/.875/.840

6.5 Grendel mags seem to work fine

I love the idea. I love 6.5 grendel. Got one in a Ruger American. Considered getting a 6ppc barrel but this seems more practical if someone like Hornady is pushing the caliber.

I called and left my info with Lamar - take my money !!!!

Don’t forget the THF member discount

Lantac has some velocities and their work on the 6mmARC on their Facebook page

Barrett has the following link on their website for news

So does this mean we can expect some ammo soon?!?!

How would this be a step up from a 6.8 120 sst?

Inside 200 yards, it won't be. If you calculate the 108 at 2620, it steps out of the muzzle with 1646 ft lbs, just a shade more than the 6.8. However, at 200 yds the 6.8 is at 1120, while the ARC makes 1128 @ 300 yards.

A good bit of this is going to depend on barrel length and just how much you can hot-rod the ARC. But there's no denying the BC on the 6mm carrying much better down range.
