line the before reloading? are you using a mec sizemaster type resizer?

[William Davis]

Old 76 Grabber,I don't know if the line is coming from the sizing. I don't think it's from the guns chamber.

Loading up some now will pay attention to not putting any in sequence with the line, see if any appear in a finished box.

I have it too, I think its from the top of the sizing collet ???

[William Davis]

I could be putting too much pressure on the crimp too, causing a bit of a wrinkle were the two parts of the shell join. But the line is more a crease than wrinkle
