Tom,
No, actually, we never did. I believe we loaded some 300 WM ammo that was headstamped Lapua, but the brass itself was made by Norma. Decent brass, but not quite the quality we would require were we to offer it as a production item for our own line. So, if you do find some 300 WM brass out there with our headstamp on it, that's the story behind the scenes. Sorry!
