After shooting the first round, my early model LH SBE will no longer lift the second shell from the carrier up for the bolt to push into the chamber. The gun has fired many thousands of rounds and has been nearly flawless for 2 decades. This is not an issue with shell size or the load of the shell. The fault occurs even when manually cycling loads. The recoil spring is new and the magazine spring is also new. All components of the gun are clean.
Any insights?
