110 30-06 Misfire at moment of truth !

[ABL1111]

Circa 1959 110 in 30-06;

Misfired last hunting season - got a second shot.

Over winter took apart bolt, left the spring and firing pin together but cleaned all and lightly lubed.

Took to range fired 4 bullets perfectly - thought I fixed it.

Misfired again today - got the buck anyway - ???

Whats going on ? I figure I’ll RR the spring and firing pin.

Sound like a good idea ?

Best place and best parts to replace with- OEM grade and or upgrade ?


Thx

Ammo maybe?
Have you tried dropping the firing pin on the rounds for a second time?

[RustyShackle]

Measure pin protusion. Replacing firing pin might not be a bad plan.

[savagecornmuffin]

What ammo were you shooting?
I have an Idea what brand already...
Yep,.. I'm already blaming the ammo.

[ABL1111]

Ammo - Remmy 30-06 200 grain.

I pulled the bolt out. Disassembled - and took top retaining washer and spring retainer off, leaving the bottom retainer in place. I dropped the firing pin back into the bolt - by hook and by crook with a micrometer, I measured the firing pin protrusion - the result is that I have .062" protrusion. I was reading a link and that is what the spec mentioned on the nose, .062". So, it seems the protrusion is correct.

How can I confirm the spring is good or bad ? I'm thinking to switch the Spring as I've read that the heavier duty one help this gun to not misfire. Any opinion on this ? And which is the best one; OEM, Wolfe - does it come in different tensions ?

Lastly, I read the below a few times and am not sure how to adjust the end retaining spring washer nut ?



" The last adjustment to make is the firing pin spring retaining nut has to be adjusted to provide at least .02 clearance between the cocking pin and bolt body when the firing pin is all the way down. Rather than measure exactly, I just made sure that there was some 'wiggle' room when the pin was all the way down. After you get the clearance you want, line up the teeth on the D washer with the teeth on the cocking pin sleeve with the sleeve slot line up properly with the cocking pin. Line this up by unscrewing the nut so that you don't eliminate your pin/bolt body clearance "

I take it they are factory loads ?

Try fresh ammo in a different brand. Had the same issue with Rem 25-06. They had a long run of hard primers on '06 size cases. You can search the website to verify if you need to. Buy some Federal loads.

I'm also assuming that the primers look like they've been struck plenty hard. Take a look at a missed fired primer compared to one that did fire. I would think they look the same.

Check the ammo man.
Have you dropped the firing pin on it more than once and what were the results?
The brand you mentioned is what I suspected may be the culprit from the start.
I have seen several posts on other forums lately complaining of the same thing with the end result being the ammo from big green.

If you hand load maybe take one of the duds apart and replace the primer and see what happens then.

Just a thought, my dad had a .30-06 Remington that he used for deer hunting. I don't see a location for you, but he was deer hunting in Northern Minnesota, brought the rifle into and out of the cabin. Had a very similar misfire. Consensus was that bringing it into the warm cabin after cold day hunting allowed moisture to condense in firing pin channel, taking rifle back out in the cold would allow the water to freeze and block firing pin.

Just a thought.

With the bolt assembled what’s the distance from cocking pin to the bolt body when in the fired position? You might not have enough turns on the firing pin spring nut that the cocking piece assembles with. If it’s too tight the cocking pin will hit the bolt body. Don’t want that.

[ABL1111]

Thx for the help. It is the CoreLokt ammo. The gun has been in the family for over 50 years - and it's not been shot that much as it's a seasonal deer gun my Dad used infrequently. It really could be the ammo. And, to be honest, I have shot (3) deer with it in (4) years with --- probably the same box of ammo.

After careful examination - the misfired bullet does not have the same marking as the (2) successfully fired cartridges. The (2) fired ones have a deeper dent and a perfect 'round lip' around the dent. The misfire round has a less deep dent and no lip around the dent. Am I making sense ? What are your thoughts about this ?

As for the temperature thing - I've thought about that, but more about dirt and too much Lube slowing the action - but I cleaned it last year real well and ... last year it was the first shot that misfired - THANK G*D this year it was the second shot, a close range, kill-shot that misfired - or, I would not have bagged this deer...

Rusty - I'm not exactly sure what you mean as I don't know the proper names for these parts.. I'll try to look up a diagram...

Thoughts ?

The cocking pin is round and protrudes from the side of the bolt body. The pin goes through a nut that threads down on the firing pin. If that nut is(was) backed out at some point the firing pin spring is not under as much tension as it normally would be. I can't recall specs off the top of my head, but you do not want this cocking pin touching the bolt body in the fired position.

It could be old ammo causing the issue, the difference you are likely seeing in the fired vs unfired primer strikes is probably slight primer crater caused by the firing pin hole being a smidge oversized or the firing pin a smidge undersized. Not a big deal.

Edit: My original post meant to say replace the firing pin SPRING might not be a bad idea. Trying to type from a phone isn't always the best way to communicate.

Aaahaa !

Now I get it. It does not touch. I reassembled it all - put it in the fired position and I can spin the cocking pin with my fingers.

So, ammo or spring. I'd like to do both.

What replacement spring do you all recommend ?

[RustyShackle]

I use the factory springs with no issues(only had to replace one firing pin spring over the years) Although I have heard of guys switching over to the 32lb Wolff spring. Probably the only real downside to this would be increased cocking effort on bolt lift. Midway or Brownells or one of the site sponsors might have these.

There is a rumor that savage is no longer facilitating the selling of parts, however you might be able to source a spring directly from savage.

[ABL1111]

I want to order a new spring and firing pin - why not, cheap and easy. I looked online and see there are many versions - long and short action of both the spring and the pin.

Which do I need ?

My serial # is 14030.

[RustyShackle]

I can’t tell by SN, but if it’s a 110 then it’s a long action. Probably a small diameter.

[ABL1111]

I bought the pin and spring from Midway. I opted for the OEM spec and not the heavier spring.

BTW - I misspoke about my ammo - its Remy CoreLokt 150 grain ( not 200 ). My .35 Marlin is 200 grain.

Once I get it in the mail, I'll reassemble all and try to go to the range.

I'll also try a new box of ammo.

[RustyShackle]

Your rifle is older? You might actually have a large diameter firing pin. Seems someone here swapped for a small pin with no issue, but it might be wise to cannibalize the spring off the assembly.

This may sound really dumb, but what are the headspace measurements at given temps. Don't discard the dumbest details. That's the one that always bites the biggest chunk out of my wallet🐒
