sako bolt

[pigpen]

finally found enough parts to finish the sako.
Started reloading for it this morning done my measuring to the bullet in getting it the right length in chamber and loaded 6. Went ou to test them and all it done was snap.
Put the 2th one in and snap.
It is hitting the firing pin but not hard enough. Do i need a new firing pin and spring or what do you guys think?

I don't know what parts you put together, but well-adjusted parts in one rifle may be out of adjustment in another "identical" one.

Check that the stock is not touching the bolt handle, preventing the bolt from fully closing.

Check firing pin protrusion from the front of the bolt in fired position. I think 40 to 60 thousandths is common.

Check for hardened grease/crud inside the bolt.

Check that the firing pin spring is not broken.

It's probably the trigger mounting bolt. Be sure the screw is moderately tight, and the locking nut tight. Never use the screw to try to get a softer trigger pull....DAMHIK.

Screw 'C' and nut 'D' need to be tight.

How is the head space?

Took the firing pin apart and cleaned it twice. Every thing looks good and seems to be moving so i oiled it a little and put it back together. It is hitting the primer but still not enough for it ot go off.
You may be right Eric t it may be just to much head space.

You can do a down and dirty, quick headspace check with Plasti Gauge.

putting a L 579 sako together that my dad left me.
It was in parts but not all of it was there. I had to
find a stock, ok that is done. Now i need a box ,
the follower and spring, then it one is ready for the
blue job. Does any one know where i might find a
box, follower and spring to finish my project.

If it is the original bolt, receiver, and barrel, it is not likely to have excessive headspace, unless it was abused with overloads.

You replaced the stock. A stock that won't let the bolt handle go quite all the way down will give the symptoms you describe. The handle should not touch wood. Have you checked that?

What cartridge, dies, and shellholder are you using? Was the brass fired in this rifle earlier? Is it new brass? Have you tried to fire a factory loaded cartridge?

If you're action is the old L579, you have an easy firing pin protrusion adjustment on it. On the back of the cocking piece, you'll see that the firing pin has a slot in it so that it can be turned in or out. On the bottonm of the cocking piece there is a small hole that has a hex head screw in it. Loosen the hex head screw and turn the firring pin in untill you have the contact needed.

pigpen, I currently have 5 Sakos. I had an H&R model 317 based on the Sako action(.222). Long story short, I had a close shot years ago at a bobcat. I pulled the trigger and all I got was a click. Tried again and click. When I got home I replaced the firing pin spring with a new one and no more click.

[pigpen]

i have checked the wood on the stock bolt and it is not touching.
Spring on the firing pin is not broken abd have tried to
adjust the firing pin but can not find a screw driver small enough to get to the screw. I am working on that part but so far everything yu suggest is not wrong. Even the trigger pul is set at 6 to 7 ounces.

WHAT NOW??????????????

[gunsandgunsmithing]

Have you checked the headspace yet? Tell us more of the story on this gun. What has been done to it as far as you know?

[Rhys]

I would check the headspacing just for out of curriosity, but many rifles will still fire unless grossly out of headspace. My money would be on your firiing pin protrusion not being right. On the Sako it is very easy to end up off on the protrusion. take the bolt out of the gun turn the bolt shroud to allow the cocking piece to drop forward, and measure howmuch the nose of the firing pin is sticking out of the face of the bolt. Should be around .030-.040. If it is less you will need to loosen the set screw on the onderside of the cocking piece, and screw the firing pin forward to get in that range.
