I have a K98 Mauser I,m working on, but Misfires all rounds. I used different types of ammo( Surplus and modern). I checked the Headspacing with gauges and passed with flying colors. The firing pin protrusion is 0.060. which I beleive Min. is 0.055. The 3- pos. safety was indead on the fire Pos. To the Left. I,m stumped ! Any ideas would be greatly appreciated ! P.S. Most of the Primers did have very min. strikes on them. Maybe the firing pin is still too short ?
