I have mentioned this M95 before. It is barreled/chambered for. 257 Robert's. Yesterday while attempting to fireform brass I noticed a further issue with the trigger. More often than not the trigger simply will not break. I'm using the Mauser trigger, as-issued for now. Pull weight measures 4-4 1/2 pounds. If dry fired the trigger action is normal, every time. With round in the chamber, mostly it will not fire. Take up is normal then the trigger stops hard and no amount of effort will move it. I am stumped.
To complete the picture, I formed cases setting the shoulder so the bolt just closes with resistance so the case heads pace is correct whenfireformed. Back home I chambered an empty formed but not yet fireformed case and tried the trigger. The mechanism functioned normally.
I am at a loss. Ideas?
