loading 6mm ARC?

[rockhound78]

Just wondering if you can use 6mm PPC dies to load the 6mm ARC?

Probably not since the ARC has a shorter headspace. You’ll bottom out on the shell holder long before you touch the shoulder. Trim the dies, maybe it works?

It’s not shorter than a ppc, it’s actually slightly longer but it is shorter than a 6 or 6.5grendel.
The ppc seater will work fine, the sizer will work the neck and shoulder fine but will not size quite all the way to the base. May work for your loads, may not.

In addition to the headspace difference, the shoulder of the PPC (.4311) is .001 wider than the ARC (.4301). This could result in extraction issues, especially in a semi-auto.

I use a Forster 6 MM PPC die to seat my 6 Grendel/243LBC, I use a Redding 6.5 Grendel Sizer bushing die to size my brass
