Home Forums Hunting & Shooting AR and Tactical Rifles 6mm ARC what do you think ?

Own a RR Varmint 223. Thinking about a 6mm ARC switchover.

Anyone played with one ?

Oh yeah. Mucho fun. Built one for the son with a Proof Research carbon barrel. With a suppressor, it is like shooting a pop gun that smacks steel a far.

Going to build one for myself this year. Just pondering barrels.

I’ll be putting 2 ARCs together in the next few months. I’ve been waiting for something like this for the AR for decades. I’ve owned literally more than 100 ARs over the years and while I love the platform itself I can’t warm up to the .223. We can’t hunt big game with anything smaller than 6mm so I never used one for hunting which might’ve softened my attitude if I’d used one successfully for deer.

I like the Grendel but I think the 6ARC is a better mousetrap all the way around.

In a bolt action mini action rifle, the 6mm ARC is my new favorite deer cartridge. Very frequently I see the 6mm ARC comes with lots of advantages in the ar 15 package. Long range energy on target is a stand out to be sure.

ordered an upper from grendel hunter, shoots excellent. sent it back to polish out the chattermarks in the chamber.
shoots 8,9, and 10 during sight in.

The case was made too short. It should have been extended to 6.8 SPC length. 85gr Partitions at 3100fps, 90gr Accubonds at 3025fps from an 18" AR-15.

Left to right - 6PPC, 6mm Too Short ARC, 6mm Correct Length ARC, 6.5 Grendel, 6.8 SPC.

I can sure see the logic of that, Tony. Wasn't there such a chambering offered? I shopped around quite a bit and found references to cartridges and chambers that had been more or less conceived but never made available. The names of those cartridges escape me now---it's been several years. There were some good looking ideas, though.

Suppose for the sake of argument one could agree that the ARC may have benefited by extending the shoulder forward for Varmint bullets. On the other hand, with 103 grain to 108 grain hunting bullet focus, I am of the opinion Hornady Got it right!

I personally like my bolt action CZ 527 chambered in 6mm ARC with a 22" barrel. Been a fine deer rifle. So far I have kept shots inside of 260 yards. Little over 2 years with 6mm ARC in bolt action rifles. Sorry I seem biased, as I do not find myself interested in AR rifles yet.

Why would you believe less powder capacity is better for 103- to 108-grain bullets???

I agree with this for medium weight (90 and 95 grain) bullets, which is what I use. It would be perfect. Just a shame making that case out of .220 Swift brass is a PITA.

I also like the 6WOA. I wished they had more support though. I would have kept the one I had, had it had the right twist rate. For some stupid reason WOA decided 10 was a good number. A 1 in 8" would have been much better. Speaking of them, they say they will not chamber one of their barrels for the 6mm ARC because of the safety factor. The bolt for the AR's being a very weak point in the design.

Perhaps you are thinking I am implying I prefer less case capacity. Not exactly my preference, though tolerable.

Proper neck placement on the shank of the longer ogive bullet profile, is the goal that is being achieved from my perspective w the shorter 6mm ARC cartridge.

If we were not trying to fit the cartridge into the shorter AR magazine, or a mini action mag in the case of my CZ 527, the benefit of the set back shoulder would not exist.

In the bolt action CZ 527, 2780 fps muzzle velocity is where my accuracy load worked out with the 108 grain elite hunter. For whitetail that seldom exceed 300lbs on the hoof, in the midwest. this load will do quite well and has achieved DRT results with the brachial plexus shot at a bit over 250 yards.

Bullets ALWAYS matter more than headstamps. The beauty of the 224,243 and 264 Grendels,is that they shine brightly in the trite OEM Krunchenticker confines. The SPC a HILARIOUS Goat Fhuqk in comparison. Hint.

Go ASC mags and they get even better. OEM Howie Mini and CZ's do no favors there and only replicate Krunchenticker COAL,in OEM guise. Hint.

Step away to aftermarket Howie Mini bottom metal and things can change. Wayne's World offering the greatest COAL latitude(2.450"+),due the thickness of the magbox proper. Hint.



Starting velocity,ain't impact velocity and the .243" 85gr NPT(.315 BC) and 90 AccuBombs(.376 BC) are HILARIOUS Goat Fhuqk's. Hint.

Pardon reality....................

The 90 grain TGK at .490 bc is good for its weight and the 95 Berger at a true average of .460 is also good for its weight. At medium hunting distances such as up to 350 yards, the middle-weight bullets shoot flatter because you can drive them a lot faster.

SniffleKchunt,

You are Google Pretending,about things you've never even seen,let alone done...you "lucky" kchunt. Hint. Congratulations?!?

If I'm going to fling 88/90's,it's going to be in a 224 Grendel,of which I've more than a few,in both Turnbolts and Krunchentickers. .545 and .585 BC's there. You feel free to use your Imagination to Pretend about "flatness" and I'll shoot Real World atmospherics and reap the inherent advantages of same,in wares that actually exist. Hint.

Big Day for you,now you can say you've "seen" same. Hint.



You CLUELESS Lying Pieces Of Fhuqking Schit are a riot! Hint.

JO Gen2 BDL metal here,so you can continue to get your Google on. Hint.





Fhuqking LAUGHING!..............

Littlestick, stop pretending that you do a lot of long-range hunting necessitating the long, heavy for caliber high bc projectiles...because you don't. All your "hunting" is opportunistic shots from a boat to some little blacktail on the shore at under 100 yards or some little critter in the water at 15 yards wanting to eat a fish. And stop being so dishonest and acknowledge that at short to medium distances a medium weight projectile with a good bc for its weight is going to shoot flatter and sometimes even have less wind drift than a heavy higher bc bullet going much slower.

If I'm hunting at long distance, it sure as chit isn't going to be with an AR-15, in any caliber.
It seems that most guys shooting the 6ARC with long heavy bullets are plinking steel, but when those same guys take their guns hunting, they are using conventional 85-100 grain bullets.

Tony

I'm unfamiliar with anyone shooting 85-100gr .243" bullets,in any chambering,as a Critter preference over good bullets. That whether AR or Turnbolt. Hint.

BC advantages start at the muzzle and never wane,to the chagrin of Window Lickers everywhere. Pardon Physics,being plumb handy. Hint.

Wayne's World Howie Mini BDL bottom and a .620 BC ARC Smooch. Hint.





The only things you Fhuqktards "shoot",is your Imagination and Pretend. Hint.
