anybody know the overall length for a nagant fireing pin spring?i picked up a crusty ole bubba sporterized nagant the other day and am trying to line it out. it will fire but only after 2 strikes on the same shell. the fireing pin spring was shimmed with another short spring inside the bolt.the long spring looks new and fine but im not sure its even the correct spring for this rifle.id hate to order a new spring and find out its the same one i already have and actually have other problems. any help would be appreciated guys.
