Re: Light firing pin strike
the bolt screws from the factory are very tight, you just have to put it on the floor and step on the wrench. make sure the wench is in all the way. A spot to check is the bolt release/ sear clearance to stock wall and the over travel of the sear clearance to the top of the trigger. either of these dragging/ friction will slow the release/ travel of the firing pin.
Re: Light firing pin strike
Thanks for the help Blue.
I tore down the bolt and reset the pin protrusion to .058. I broke down all the rounds that miss fired with multiple hits of of the pin at the range last time. All but one of the primed cases fired with the new pin setting. Hope to get it to the range today.

Re: Light firing pin strike
If it by chance has a three screw trigger the over travel may be adjusted too tight. I had one that the sear would drag on the trigger slowing it down enough to cause problems.

Checked everything for clearance. Pretty sure I have the problem fixed.

Re: Light firing pin strike
I had trouble with blowing primers and finally found my firing pin was at .069 and I reset it to .032 and it works well. Billpa says he sets all of his at this.

What looked like the cause?
I am curious as well as the fact it can help out others with similar problems. There is another thread right now with the same symptoms you describe.

EEK, .069", thats a bunch. In effect anything over about .030" stops the pin fall shorts thus reducing primer impact pressures. Not saying that was the only problem, but it sure wasn't helping anything either.

Re: Light firing pin strike
Thought I had everything fixed, still got light strikes. Tore dorn my 223 bolt and to see anything different. Upon reassembling I noticed how much harder it was to compress the 223's spring, orderred a new spring for the 250 and it is much stronger than the old one.

Re: Light firing pin strike
Heads up on my problems, the new main spring did the trick. Everything is working just fine now.

Re: Light firing pin strike
If changing the spring did the trick, that would indicate to me that the firing pin fall is short. I've never seen a Savage spring that was weaker than factory specs., but the majority are over factory specs. If it was on the low end of specs, the only thing that would keep it from igniting a primer is short firing pin fall, basically lack of momentum.
