6mm ARC

[TomD]

Would factory 6mm ARC cartridges fire from a 6mm PPC chamber? There are such wild variations in the published PPC chamber drawings, it's hard to figure out.

Of course, there would be the thing about firing 100 + grain bullets from 17-18 twist

Here's the ARC drawing

Very similar to a custom PPC, but the base to shoulder dimension is about 0.040" longer. So, no, it wouldn't chamber.

I'd guess it's about what a 6mm Grendel would be, but I don't have one of those to reference.

Edit: After a little reading it looks like the ARC case is longer than a PPC but shorter than the Grendel by 0.030".

Wonder what you could do with a .308 head cartridge?
