Hi All,

I need help locating a savage short action firing pin spring somewhere in Canada I have 8 on order from the USA but I really need one soon. I am having some mis fire issues in a rebarreled savage FTR. The gun was converted from 308 to 300wm. I do get some rounds to fire but on 30 only 9 worked. Factory rounds also mis fire. Headspace is fine the only last thing that could be the issue would be the trigger but it doesn't seem to rub unless I ain't looking in the right place.

Thanks

Check your firing pin protrusion. If not adjusted for the magnum bolt head, you may not have enough protrustion to reach the primer.

It is very rare that the spring is at fault.

Also the trigger, sear is not going to cause issues with the actual ignition. The design is such that it cannot affect the firing pin movement.

Hi Jerry,

I've ajusted the damn thing till it was sticking out and I cant seem to get ignition on consistent basis. If it aint the spring and the trigger can't be at fault I don't know what to do. Maybe change the trigger shorten the bolt head neck... Very puzzled

Thanks for the help

There is really only two things that can stop a Savage from going bang assuming the parts aren't broken.

Firing pin protrusion or headspace. It is a very fool proof design.

Take the bolt out of the action and drop the sear - big round head at the back of the bolt. Measure the firing pin protrusion and see what you have.

Get a headspace guage and confirm you are on a go guage not a field guage or something bigger.

For a target rifle, you can go right near zero headspace so the case indexes tight on the belt and bolt face. With the proper firing pin protrusion, it has to go bang...unless something is broken.

One other thought, do you have a large firing pin with a small pin bolt head? You shouldn't given the description but that is the only other compatability problem I can think of.

I would recheck the two main areas as these are the areas I think could cause the most issues.

what do the primers on the ones that dont go bang look like ? do they have a dimple? I would say it is headspace , had the same problem with my 300wsm , sent it in for repair and it was the headspace. The primers did have a slight dimple and some rounds would go off , but when the firing pin is pushing that case forward it looses its energy and wont set it off , just my 2bits

The primers on the rounds that did not go bang have indeed a dimple. I will recheck the head space this barrel has been changed by someone thas has numerous rebarrellings behind him.

Savage arms also has numerous rebarrellings behind them and mine came from the factory like that;)
 
Savage misfires

The Savage (basic 110 type) bolt has an adjustable firing pin that can be adjusted for protrusion. If someone has had the bolt apart, and turned the Striker Stop Nut, then they could have shortened the firing pin travel, so that it is not coming out of the bolt face far enough.

In my NRA firearms assembly book is the warning:
Remove mainspring by unscrewing cocking piece and removing cocking piece lockwasher..............DO NOT DISTURB STRIKER STOP NUT AS THIS NUT IS ADJUSTED AT THE FACTORY TO GIVE CORRECT FIRING PIN PROTRUSION.

Take it to a Gunsmith who knows what he is doing, and have him check the firing pin protrusion at the face of the bolt.
 
Here's another question as anybody tried this before? Turning a short action savage in a rifle capable of firing a belted mag case? If so pm me I have a few questions. I am looking for parts used and where they came from? I used parts from SSS which consist of magnum firing pin, mag baffle, mag bolt head and custom Brux barrel. I know SSS know makes modified bolt heads that ables one to use a short action firing pin instead of swapping it out. I am thinking of trying that with my bolt head.

Thanks
 
Why not just pick up a Savage in a WSM and all the work, cost, hassle and headaches are done?

SSS can no longer export.

a true standard length magnum will not fit into the mag of the new SA center feed mag. single feed, sure.

New gen bolt heads are pretty much all the same length differing in the size of the bolt face and parts.

If you have a magnum bolt head, just throw that into the SA you have now and fly at it. Of course, adj the firing pin protrusion, etc, etc.

Here is what I have done.

Taken a 308 FT/R

Changed the barrel to a 300wm chambered barrel.

Installed a Mag bolt head and front baffle. This bolt head when compared to the 308 bolt head the mag is longer.

Installed Mag firing pin which is longer. I have been playing around with firing pin protrusion. Right now it is over .0520 and does not fire on consistent basis. I will be reducing that to 0.0320.

I will be taring it apart some time this week to re-check headspace. But I believe it is not the problem as the barrell was headspaced on the go gauge very tightly.

I will also be polishing the bolt head firing pin channel as it looks rusted. That's the way it came to me.

Right now that basically where I am at. Buying a WSM would be a good idea but I wanted to use a target single shot action, I really dont need a mag and wanted the extra rigidity of the target action.

Thanks

I reduced the firing pin protrusion to something more realistic and boy oh boy did it make a difference. The firing pin is snapping like it was supposed to. Protrusion was set at 0.0430 to accomodate the lock ring but when the bolt is assembled it is more like 0.0380.

Thanks all for your help, hopefully this will be then end of the mis fire issue.
