Howa mini action in 6mm arc

[Lkwebb]

Here is my newly built rifle by www.dpgunworks.com
6mm arc 24 1/2 Sendero barrel 1/7 twist from x caliber barrels.

Slick!
got dies?

Waiting on my fl die and my collet die.. have my bullet seating die

 

[Marksman]

Have you at least run some factory rounds through it?

DANG NICE RIFLE SIR I GOT TO GET STARTED ON MINE NOW

 

[Lkwebb]

No sir I haven't..
My gunsmith shot a few rounds out of the barrel on a mdt chassis with factory ammo.
I also can't find any ammo in stock.

Thank you sir.
I'm not much into the ar 15 platform , so I knew I wanted the 6mm arc in a bolt action

THATS FORSURE ME NEITHER BUT YOU GOT A LOOKER THERE

PMing you source.

The Howa Mini action makes that barrel look big.

I like the idea of the 6 in this case. The 6-223 has been passed over by many, yet it and variations of it are great shooters.
Before you had the 243 WW or larger and that was it. I am tinkering with a 22 Nosler, just because I had a needy 223. I wished I had went with the 6mmNosler but found a killer deal on a fair bit of ammo.
I may well look into the 6ARC, I would entertain real world equal platform info on the 6ARC vs 6mm Nosler.

Look forward to more of your work with the rig.

I have liked the looks of this new 6arc round since it has been announced. But for a bolt gun, wouldn’t a 6-47 Lapua do about the same thing?

It'll do a great deal more! Case capacity in grains water rises from somewhere around 35gn for the ARC (assuming c.1.5gn less than the Lapua Grendel case) to getting on for 47gn for the 6-6.5X47L, and the capacity to bore area rises from c. 760 to 1,020. (You've missed out the lower capacity 6BR and 6Dasher anyway between the ARC and 6-6.5X47L for those using 0.473" dia. bolt-faces.)

Increasing case capacity to bore ratio makes a cartridge less flexible (and the 6-6.5X47L has a poorer reputation here than either BR of Dasher) and increases recoil and barrel wear - against performance increases of course at same pressures.

With a likely case to bore ratio of ~760, the ARC is in the same bracket as high barrel-life numbers such as 223 Rem (738) and 308 Win (747). For those who don't want to hit plates in a stiff wind at >1,000 yards or compete against the Dasher in mid to long range BR and suchlike, the ARC promises a ballistically efficient, low-recoil, easy to load and tune, accurate number which is also economical in terms of powder consumption and barrel life.

Horses for courses depending on what the shooter is looking for.

ThankYou. That was very informative!

Brownell’s has some 6arc Black ammo in stock today.

Ok thank you

Like the idea but why a 7 twist?

7.5 is standard, they're just losing out on some of the very light projectiles, at worst.

Would a slower 8 twist be a no go then for 105 grain range of bullets?

Just depends on the bullet. Hornady 108 ELD-m 6mm claims to required a minimum 1:8 twist. Just lookup the bullets you're interested in to be sure, some designs may require faster twist rates than others even of the same weight.
