The brass I have is once fired Hornady 6mm ARC. These are from both 108gr Match and 103gr Hunter ammo. I do not have a comparator or gage but looking at the SAMMI spec sheet and factory ammo vs reloads, it sure looks there is no shoulder bump. Assuming this is correct, does that point to a problem with the sizing die since typically you set shoulder bump by adjusting the die?
I have no experience with or equipment for annealing. This may be a necessary investment if it will help with the sizing.
I plan to call Hornady tomorrow to see if they can enlighten me.
