I just used a brand new 2 die (full length) set from Hornady last night. When I disassembled the dies to clean (de-grease) them I noticed a small pit in the shoulder area of the sizer die. You can feel it with a plastic tool. It does NOT mark the shoulder of the brass when sizing. I’m guessing the material had some porosity there when the reamer was cutting the die? I used the die and no problems. Has anyone ever seen something like this? I’ll probably call Hornady customer service Monday and ask about it. Since it doesn’t mark the shoulder of a sized case I could live with it. But I have other Hornady and RCBS dies and never seen it before. I attached a picture below. The pit is at 11 o’clock. There are a few cotton fibers in view from cleaning out the case lube after sizing.
