From what I'm lead to believe, the Lapua test center only uses and offers Lapua ammo.I am reading this correctly, Lapua had SK there to test? When I went it was only Lapua that they offered. I will advise anyone going in Winter to the Ohio Facility, don't not go on a Monday..Luke had an awful time getting the sensors to read, he said it happens a lot during the cold months on Mondays from not being used over the weekend..
