New 6mm Advanced Rifle Cartridge

[MarshallDodge]

Much like 224 Valkyrie when it first came out (then flamed out spectacularly) this interests me greatly in a CZ or Howa mini action, but not really at all in a semi auto platform.

This will actually benefit the 6.5 Grendel Guys too as it gives us an additional choice in bolts & mags since the ARC & Grendel have a commonality with both.

Oh, & friends don't let friends buy BA/Aero or Faxon

@js8588
I've seen quite a few issues with BA but what is the issue with Faxon and Aero? Is it specific to the 6.5G?

BA & Aero are actually the same company. Aero bought them a few years back.

Faxon is very hit and miss as @Varminterror noted upthread.

I -suspect- both companies have issues with their nitriding process at the price point they offer but that is purely speculation on my part.

Not for general consumption by or issue to rank and file infantry.

Looks like they’re replacing some of the SR25 type applications. More ammo for less weight, lighter rifle, but still reaching past 600yrds. Apparently some interest in defeating intermediate barriers also. The contract is for 18” Rec7’s with match grade Proof Research barrels (all assumptions are for steel barrels, not CF).

Specially Forces Usage?

I guess I've been lucky as my 18" Faxon Gunner 5.56 barrel shoots well. Thinking about one of their 14.5" barrels next.

If Kimber would just cut another 1/2" out of the 84M.....

Kimber should have done exactly that and call it the 84S for "short" which would have been consistent with 84M and 84L. It would require a new bolt, new stock and new extractor in addition to a new receiver but it would have been a good move with little additional cost. The molds for the Montana stock made in Costa Rica would be the only significant up charge.

They should have done it for the Adirondack. Funny they say it was for my area I hunt but never seen one in the woods.

Cuz they're tree ninjas, you WON'T see one till they want you to and by then, it will be too late!

Is anyone offering the 6mm arc in a bolt action?
Is there any advantage with it over 243 or the other 6mm rifles?

I just read the thread, watched the linked videos, etc. I'm not an AR guy. If I were, this would have my attention. But I don't see the advantage of the 6 ARC over a 6 Creedmoor in a bolt action. Am I missing something?

Interesting points I see for this in a bolt gun are:

- It's sort of like a 6PPC optimized for heavy bullets and with factory ammo support.

- In one of Hornady videos the Chief Engineer said that if you were loading for a bolt gun you could net an extra ~100 FPS over the 52ksi factory ammo by loading to a bit higher pressure. Assuming that's true you're looking at up to 2,850 fps for 105gr/108gr bullets, up to 2,900 fps for 100gr/103gr bullets and even faster for something like the 90gr Accubond. Seems like a lot of bang for <30gr powder and very low recoil.

- 108gr factory match ammo, at least for now, is a few to several dollars cheaper than 108gr 6mm Creed factory match ammo, and only about a dollar more than 73gr .223 factory match.

- Longer barrel life than the 6mm Creed, but with better external ballistics than anything else offered in a mini action, and many cartridges offered in short actions.

.223 bolt guns are a lot of fun and relatively cheap to shoot. To me the ARC in a bolt gun would be in the same spirit as .223, but a little more expensive to feed and much more capable at range.

Specially Forces Usage?

All folks say in the videos is that the Barrett contract was to "a notable DOD entity", so yes almost certainly SOCOM or a component. They often buy differenty stuff to experiment with, then junk the stuff they don't like and keep the stuff they do at a much faster tempo and with different requirements than regular DOD.

Over 243win factory rifles, the ARC is twisted to handle the high BC 108-110grn bullets which escape the 243win’s slow standard twist, it uses 10grn less powder and has about 25% less recoil, and its barrel life is twice to thrice that of the 243win. Same stuff I mentioned a page ago about 6 ARC vs. Creedmoor.
