Justin, I an many others have got busted HARD on this issue of Lapua, Norma, and PMC Web dia at the .200 Mark and also thicker necks than Winchester brass/Rem brass.
Acklyman you were correct, I took a case and sample bullets to the gunsmith today and my Lapua brass is .004 thicker, he is going to see if he can get a reamer that the Lapua brass will work with. Thank you for bringing that up and hopefully stopping the headache before it happens.
