I assume it is the firing pin but I would like to know if someone else has an idea. I have a Remington 572 pump 22 that hits the case each time but does not fire all shells. Not an ammo issue. I have used several and does the same thing. I assume it is a firing pin but any other ideas if that doesn't work. It is not hitting hard enough in rim just wondering about possibilities.
If the firing pin channel is not full of trash it probably is the firing pin. The tip of the firing pin will break off. It is very difficult to see without a new firing pin to compare, unless you are a gunsmith who sees broken firing pins all the time.
A steel firing pin and brass .22 ctg case, with that pump remy to wear one out is kinda doubtfull, make sure the floating chamber is clean and moves as it should, most likely the bolt and trigger/ hammer group are gummy with powder residue and old varnished up lubricant.
