I have a new dasher barrel I just received chambered in lapua dasher. I was hoping the lapua br brass was going to show up during my barrel wait time but it has not. I am thinking of getting some norma brass to play with for now till the lapua brass is available again. What would I have to trim the norma brass to to be able to work in my lapua chamber? Will any neck turning be required? Or any other brass modifications be needed?
