Thread: Lee easy trim mistake

So I did a bit of a boo-boo yesterday while trimming up some 7x57 brass.
Had done some load work and wrote the load on some sticky tape and stuck this on the rounds in question. Cool idea I thought…..yeah in cool weather or only if you go straight out and shoot them.
The tape left some residue on the brass and which then snagged up on the O ring which then ripped it right out the die body.
Anyone happen to know the size of this O ring? Yes yes get your callipers out….I would but it needs to fit inside the little grove. Anyway just thought I’d ask here just in case someone may know the answer.
Cheers
