Well I took the die to work today and threw it in the lathe, using a med fine lapping compound on it. It easily opened it up , first time I ever used a lapping compound so I learned something new today.I had to shoot a couple rounds to have have brass to reload, it worked like it should now. I see Midway just got a new shipment of .223 AI dies sets in. Thinking I'll wait, I just picked up two more cans of Varget today, got 100 Lapua brass bits coming with a few target bullets.
