Making 6 Arc from Hornady 6.5 Grendel

[CZ527 Guy]

Any parent brass for 6mm ARC seems difficult to source as of late. Pretty sure it has been done with every option out there. I have done the 220 russian & 6.5 Grendel with good results. 6.5 Grendel conversion is the most straight forward starting point based on my experience.

Lapua 220 russian

Horinady, Lapua, Starline & PPU 6.5 grendel

7.62 x 39 of various brands.
