I just acquired a very nice mid 60's Anschutz 1413 Super Match with a 5039 set trigger. I had it to the range today and it shoots very well, except halfway through about 25 shots in, it decided to decock on loading. It will #### when I set the trigger and load, but not before that. It worked great before this. I'm thinking a sear problem but I can't find any explanations on how to remedy or set this. I've read a few articles on degreasing the trigger set, but I thought I might wait for those in the know for help. Perhaps, if it is a sear problem someone can steer me in the right direction. Thank you.
