Editor’s Note: For those readers who were asking for more info on 6mm ARC.
USA – -(AmmoLand.com)- Throw Out the Old Rules! Until now, true long-range shooting from the AR platform has largely been reserved to larger “AR-308” rifles. Those old rules go out the window with the 6mm ARC from Hornady – a cartridge that delivers an 800 to 1,000-yard effective range from a standard AR-15 platform.
What is 6mm ARC Ammunition?
The 6mm ARC cartridge is based on the 6.5 Grendel case necked down for 6mm bullets. Good News! If you already have a rifle chambered in 6.5 Grendel, the ONLY thing you need to change is the barrel. Everything else – bolt, magazines, gas system – is compatible with 6mm ARC.
Other pluses:
- 6mm ARC fits standard AR-15 rifles & Short/Mini action bolt rifles.
- Built-in 30-degree case shoulder for reliable feeding.
- Short, squat case profile similar to the 6mm PPC, one of the most accurate bench rest cartridges ever.
- SAAMI spec cartridge, so NOT a fly-by-night Wildcat!

Waiting for military to switch out to 6.8’s, and THATS what I’m adding. Once it becomes military standard issue, ammo will become plentiful and cheap. Better to carry rifle that shoots a common round than a specialty round. In a pinch you want ammo that is easy to find.
Think I will just keep my Grendel…people always chasing this latest and greatest crap…
Nice little blurb, but….where is the data? Ok it keeps supersonic out to 1,000 yards. I’m not seeing anything but bullet weight of 103, 105 and 108 gr. and the speed, beyond that nada. Or did I miss something.
Wikipedia to the rescue,
6.80 g (105 gr) BTHP BLACK 838.2 m/s (2,750 ft/s)2,388 J (1,761 ft⋅lbf) 24″ barrel
Larger-sized AR-10 performance cartridges such as 6XC, 6×47mm Lapua, 6.5×47mm Lapua, 6mm Creedmoor and 6.5mm Creedmoor have better long range performance compared to the 6mm ARC, but have more recoil, as well as overall lengths that make them unable to fit in an AR-15 sized magazine well.
A good 6.5 grendel works just fine, ammo is cheaper and available and I don’t have to mortgage my house to buy something else. Right now, with everything going on, I would rather invest in ammo, more than another upper, more than gold. If things go sideways, and I have to believe they shall, I want a proven tool, reliable and accurate.
Arm up and carry on
Just another big push advertising and media push of something new! Just like the 224 Valkyrie a couple of years ago, where’s that cartridge now? 224 Valkyrie barrels are now sitting unwanted in the bargain basement clearance sales. I’ll let the brave and daring waste their money first on the latest eye candy being pushed by advertorials. Just a parting thought, where have all men gone? All this new and latest crap is being push on the premise of less weight, less recoil, reduced loads, lighter bullets and smaller calibers. Yes more and more women are getting involved in the… Read more »
I will stick with my 6.5 Grendel as it works just fine . Finding ammo in this era is tricky , why would I want to have something that may or may not have ammo available in the future ?
Intrigued, but I’ll give it a year and some real world data and review. But this may, if t holds up to the hype, be the reason I finally break down and acquire a AR15 platform rifle (and maybe a new Bergara HMR)
What with the FJB inflation rate and my dwindling fixed ( retirement) income, the only way I’ll ever get another Rifle/ pistol are the ones you pick up on the battlefield- in the meantime, my .308, 5.56 and 9mm
gives me ammo available pickups .
Uh…is that a LAW in his safe????
How does it compare with the new service standard the 6.8 enhanced Ammo?
