So I just started noticing these vertical marks on the shoulders of my 30-30 brass.
Happens during the decapping/resizing phase. I use the Lee hand press and dies. Marks are about 1/16th of an inch wide, don't seem to go all the way round the brass. I looked up inside the decapper and could not see anything that might be causing this.
I am leery about using this brass now and if I can't find the cause of the problem I am going to end up buying a new die from Lee.
I will try and post pictures soon (my camera phone wasn't cutting it).
