Thanks John, I ended up pulling the parts from the first one and using them in the second. The action was then hard to jerk closed but smoothed out after some work and shooting. The safety needed changed over to be original, then didn't work. That was a quick fix. Took the bolt apart and cleaned it (also filed some metal on the sides). It appears the firing pin is a little worn as still the odd FTF. (very little dents in case) My first range trip (first M) I was using .22 shorts as the receiver is not in the best shape. The change over to the latter M lets me use LR standard velocity (I will stay away from high velocity).
