Triple check that you are seating the primers all the way, I had a issue a while back due to a poorly designed priming tool that lead to several duds. A primer not seated all the way won't ignite properly because it will slide forward on the strike making for a mixed bag of shells that will and won't work. Have you tried any factory ammo?
Owned half a dozen Savages and have had no use for their customer service department they have all been flawless (unlike SOME rifles)

I love that load too, mix with 150gr Accutips and you have my most accurate 30-06 load.
