I doubt anyone has spent time developing loads for the lighter projectiles. I would love to have a load for the 58, 70, and 75 grain projectiles. With Brass rarer than hen's teeth, and factory ammo continuing to go up in price, it will be a while for me.
Seems like everyone is in love with the 100+ grain pills. I think this would be a great 300 yd and in round with the lighter bullets for coyote.
Now, we wait....

The 6 ARC interest me also,
I have a 6x6.8 and have loads worked up for it with 58 and 65 VMAX's.

Don’t have any ideas about a good load but
Friday night was the first time I saw brass available since the cartridge came out. I would have had one if I could have found brass.

With about 6 miles of jump for the 58s I would be surprised if anybody has a real tack driver load.
The ARC was specifically designed for long high BC bullets with a long throat and fast twist, polar opposite of light bullets.
Pretty sure Alf went down this road as well as others and the lightest load that produced good results was the 75VMAX.
Goodluck TJ on your quest, I'll keep an eye out for a 58 load.

I'm running a 75 speer hp in my Howa bolt gun. Max load of xterminator and seated out a little further than what book calls for. Absolutely wrecks prairie dogs. Haven't shot it on paper past 200, but is seems to be very accurate on steel out to 500. It's just a truck gun with a lower end Vortex 6-18 package deal scope on it for now. I haven't shot any thing larger than prairie dogs with it, but from what I can tell by those results coyotes should be no problem, and a good chance well placed shots will be drt, with minimal fur damage.
So far I am really liking this rifle, load and cartridge. This is the lightest bullet I have used, but I am going to try the 62 Barnes VG sometime soon, too.

Best friend tried a bunch of loads in his Savage 6Arc,never got anything close to acceptable with the 58 grain V Max.Working with 87 grainers now.

6ARC is only cool because it fits in the AR15 platform. There's better options for a bolt action.
In the AR15, 6ARC performance with 55/65gr bullets doesn't seem to beat the 6x6.8 variants @ 3500+fps, the only benefit of 6ARC is possibly better brass quality/supply.
Most ARC barrels are optimized for long bullets. But if you order a custom barrel you can easily change that. For an AR15, give Dtech a call and have them spin up a 10 or 12 twist for more versatility.

Best brass for the ARC is to make it out of Lapua.....

D-Tech does not have reamers for short bullets, so you're still handicapped by their chambers with long freebore.
I just went through this with my 6 Hagar. Their reamer was .117" freebore. I bought one online and sent it to Manson to be reground to zero freebore, then sent it to them to chamber my new barrel.
Too bad they don't order zero freebore reamers, and use a separate throating reamers for a true custom chamber for the customers.
However, their 22 DTI is one I can speak to as to having the perfect throating for lighter bullets. I can touch the lands with 52 Bergers, the only bullet I've shot in it.

I've had 3 ARC's. 1st two were Aero precision uppers from Brownells. 1st one sucked for accuracy with about anything. The 2nd I finally found a good load with 87 Bergers. I sold that one, and ordered a barrel from Ranier Arms. (Shilen)
I tried Nosler & Sierra 70's again, of which neither worked. Never tried any 75's, but found nirvana again with the 87 Bergers, which would hover around the half MOA mark. Sadly I sold that one to build a 6 Hagar.

What twist? Assuming the Aeros were 1:7 and would struggle with light bullets. How about the Shilen twist?

Pretty sure it was a 7" also.
Which brings me to another point you're alluding to. I see time and time again people stating their fast twists shoot lighter bullets just fine. I guess it depends on what their definition of "fine" is. If that was the case, why don't barrel manufacturers just offer 6 or 7 twists across the board to simplify production and inventory?

It was designed for long bullets... but I dont think the barrel manufacturers got the message. In my 18" Proof CF barrel I can not load 87 vmax to Hornady recommended length. My bullet is jammed into the lands at their 2.140" COAL. I had to shorten them up over .050" to get them to shoot well.
There are plenty of people loading 58's with good results.
But I would agree that in the lower weight ranges the ARC is almost a waste of time. Is there any difference in shooting a 6mm 58gr at 3250 vs a .223 55gr at 3200 (both would be higher in longer barrels)?
I think the 85-90gr range is the sweet spot between speed and energy on target.
