So I reloaded some more .243 Winchester loads with once fired cases today. I used 95 Grain Hornady SST loads. I noticed this once before. Anyway, on some rounds when seating the bullet the handle is a little hard to pull. It seems to be shaving a slight bit of copper off of the copper jacket on these. I pulled a bullet to see where it was shaving it from as I could see shavings. Turns out it's right around the very edge on the bottom of the bullet. You can see where the shavings were from, but not feel it. Seems almost like the case mouths are too tight after being re-sized and it's just shaving a little off of the bullet jacket when it has to push it into the case mouth. Any idea's on whats going on? When I noticed this before I didn't see an accuracy difference in that batch. In general is this okay? Or is it going to cause accuracy or safety issues?
