I'm still a couple months out on my barrel, but I've been trying to purchase all the reloading components I'll need. I didn't want to keep holding out for ARC brass so I picked up 300 pieces of Lapua 6.5 Grendel brass. With there being some differences in the shoulder from Grendel to ARC, my question is, when I size this brass to 6MM ARC how far do I push the shoulder back?
