Thanks for the info,I've know about the spring load firing pin ever since Murray invented it. I just made the decision to go in a different direction and leave my rifles as is.
I started reloading for my SKS rifles long before Murray's pin was available and Mi-Spec primer were cheap and readily available and I have more than enough of those and other components to last me as long as I'll be shooting as well as several cases of surplus ammo stashed away for a rainy day.
