Got this reply from Gene a few days ago.
I chambered up a new 220 Beggs no-turn barrel over the weekend with a new reamer I got from PT&G. Everything works perfectly and it shoots terrific. It's such a pleasure to pluck new Lapua cases from the box, load 'em and shoot! No case prep whatsoever.
I have several different 22 bullets on hand from Forster, McGowen, Tucker, Ronnie Cheek and Stu Harvey. The Tucker 52 BT's were handy so that's what I started with. I'll try them all now that I know I've got a good barrel.
