David Tubb used Wolf primers exclusively at one time. By the way at the F-Class Nationals at Raton this year one of the winners was James Crofts.He won using a Savage Model 12 in .308. http://bulletin.accurateshooter.com/...-walnut-stock/ Beautiful rifle huh!? Guess the 200g Berger, Varget powder, and Russian primers did ok for sure!!
