Thanks gunnut,
The reason I want to replace the spring and firing pin is because I just had the gun rebareled from a 30/06 to 280ai by pac-nor. The action was quite old and I just wanted to "freshen" everything up. I figured since I spent the money for a quality re-barrel, trued up action, lapped lugs, mcmillan stock etc, why not? The spring does "feel" weak compared to another 700 (300 win) I have which is only a few years old. This will be my primary whitetail and mule deer gun and would hate to have somethng (a 30 year old main spring) malfunction in below zero weather when a once in a lifetime shot presents itself.
