I am new so please bear with me,as stated above a have a winchester Model
75 Target, Mfg. 1948.
Was having troubling with some brands of ammo would fire one or two then skip three or four. It liked Federal Game-Shok the best and Winchester Super X
the worse. The trigger was set quite light but if you put the bolt fown quite hard it would once in awhile discharge, well that was not good so I did the following.
I put a new Firing Pin, Firing Pin Spring, Breech Bolt Plug. It now workd fine and shoots anything I put in it, but I need to adjust as the trigger has a heavy pull now, so any advice would be welcome. This is the first rifle I have had to adjust.
MY 7MM- wsm has the accu trigger but have not had to do anything to that , besides it is quite different and I have a manual for it.
