Ive reloaded pistol ammo for years, just trying rifle for first time. Have a lot of saved 303Brit rounds (all from my gun) to play with. Have dies set up according to die instructions and the full length sizer die is putting a small vertical line in one spot on the case shoulder. It can be felt but hard to see. As much of an abrasion as anything. Ive disassembled the die and looked inside and cant see any scaring or marks to cause the issue. Should I worry or skip it and just neck size it.
