I need help. All my prep was done correctly. The bullets are Berry Bullets, .380 ACP 100gn RN. These cartridges were NOT crimped, just seated within specs at .962. I am using a Lee seating die. Does anyone have an idea why I am getting these indentations on the side of the brass? It almost appears as if the bullet is too large or the case is to narrow? They are expanded to a comfortable flair. I gave done so many of these. I really need help on this. Any ideas?
