Question

I have a Belknap model B-964 22 cal. semi-auto in the shop, same as a lot of other guns we get “it was working fine until a friend of mine who does gun repairs cleaned it for me”. Well the customer brought it in complaining that it now fired

when you released the bolt to load a round in the chamber. I took it apart found the extractor was bent out almost straight and was acting as a firing pin. I forgot to mention this gun is very similar to the Savage 87J or the Savage 6J that Bob covers in the course. I got a new Savage extractor,

installed and fit it and that problem was fixed. However now the gun will fire a loaded round, extract and eject it and load a new shell but the gun will not fire this round. it seems the bolt is not coming back far enough to catch the hammer on the sear. I have taken the gun apart a number of times, everything seems to be working smoothly with no binding or rough spots. What should I be looking for, I am truly lost.
