Gunsmithing Savage 112 bolt/firing pin

[OldBrokenCop]

OK...so I acquired a Savage 112 from a friend for the right price (free!). It had been in a house that had been flooded while he was on vacation and was "ruined" with rust. On a hail mary, he stripped the thing down to nothing and sanded it down to bare metal to just paint it and try to save something.

Well his skills were not quite up to par and he couldn't get it reassembled again. Me being the helping type, agreed to take it off his hands. SO, my problem is this...in putting it back together I see that there is a factory preset on the front locknut that determines the depth of the firing pin strike (forgive my ignorance of technical terminology, I understand all the mechanics, but am still learning some verbiage). Well, he had stripped even that down to insure there was no lingering rust.

Is there a way for me to set this, or does it need to go back to the factory?

If I remember correctly. Set the front for the correct protrusion. Then set the the rear so that the cocking pin sits just above the bottom of the cocking ramp of the bolt body.

Just make sure that the notches on the firing pin assembly allow for the cocking sleeve to line up the the hole for the cocking pin.

Hope that made sense.

That did make sense...that "front protrusion" spec is the holy grail that nobody seems to want to share.

Any help there?

You won't find a definitive answer, but 0.050"-0.0625" will probably work quite well. I'd tend to go towards the deeper end of that spec to ensure reliability.

I go a little shorter, but try for the longer of the range.

0.040" to 0.045"

Thanks to you both! As a fan of all things Google, I suppose that the search criteria I entered was wrong because I found nothing near as helpful as the links EB posted. And GG thanks for the reminder on the cocking assembly!

Happy Hunting!

Any time. I spend a ton of time on Savage Shooters. Some of the info was bound to sink in at some point.
