Slightly off topic, but can someone tell me the difference/advantage between the 6mm ARC and the .243 Win.?
I would think an AR-15 design built around the .243 Win. would be possible with less effort/expense than the 6mm ARC.
I'm thinking about a new military rifle&cartridge on the AR-15 platform as the 6 ARC seems to be,

I'm waiting for my solution. Starline accepting backorders for "Grendel Basic Brass" which is, to me, unformed, unmarked 6mm ARC cores. They advised me to anneal the brass below where the 6mm ARC neck will form.Bumping out of curiosity. Anyone else come up with a solution for ARC brass?
We'll see. In the end, if 6.5 Grendel is not available, and I've been looking for months, then this is the next best option. I tried to form 7.62x39 and ended up with a belted case...same as when Johnny's Reloading attempted to go straight to 6mm ARC. He was successful sizing to 6.5 Grendel first, then again to 6mm ARC...or shallwe say "sizing and working in several stages to avoid creasing the necks or buckling the shoulder.Working with Starline Grendel basic would seem to be much more work than just sizing and trimming 6.5 Grendel. I assume the basic brass would require sizing and working in several stages to avoid creasing the necks or buckling the shoulder.
I did talk to Starline briefly at SHOT. I asked the rep about both 6 ARC and 5.45 x 39. He said both casings had been requested by consumers but that Starline has no current plans to make either.
I'm not particularly surprised that 5.45 might not be something they are readily working on but 6 ARC would seem to be an easy button product. Time will tell I guess.

All for naught now. Starline has officially announced 6mm ARC brass. It looks like the first batches are already sold out. Hopefully another run will be produced shortly.
I left them a message on line to start making it. Rumor around my area is that they were making it for Hornady anyway.I don't think starline realized how popular the arc is, I'm sure after getting a bunch of calls they seen how much money they would loose out on.
I sent them one after that video they made pretty much offing the round and saying there not interested in making any.I left them a message on line to start making it. Rumor around my area is that they were making it for Hornady anyway.

I know it would be pretty easy for them they just didn't seem willing to make any on the video I seen.Eh, if a maker is already making the same case head, then it’s just a matter of around $10-15k in new tooling for the shoulder and neck, even less if they don’t need to draw a different wall thickness. The marketing for the new case would cost more than the tooling transition.
The really hard transitions are when a new head like 6.8spc comes out and they have ZERO tooling to make the case, even the case head - or folks like Lapua which simply don’t make belted magnums - adopting that tooling to start from scratch is a big investment. But the ARC is on the same basic gear as the x39, so adopting the ARC is super cheap, relatively speaking.
