Silly question to some... is this firing pin already bushed?

[Tomekeuro85]

I had this rifle put together by a reputable smith... but it was a while ago and I don't remember if he bushed the firing pin.


The idea behind bushing the firing pin is to make a smaller clearance hole for the firing pin. Well, it appears to me that there is almost no clearance here whatsoever.


Should I assume it is bushed?

 

[itchyTF]

I would think if it was not bushed, how could it be improved with already minimal clearance?

 

[Drop Port]

Can't tell from a Pic , most often the pin is turned to .062" I would start with measurements or call the smith that did it and he can shed light on what he does and measurements.

 

[spclark]

If it is your 'smith did an exceptionally fine job of it!

That pic's just clear enough for me to see a fine circle where I'd think a bushing might be... but the conspicuous lack of any color change from bolt metal to a bushing is making me think no, it's not.

If it's stock, it's a tight fitting firing pin hole that's evident! Are you seeing cratered primers now? If the pin mics 0.060" - 0.063" I'd say leave well enough alone.

 

[Preacher]

Stick a bore scope in the other end and you can tell pretty quick if it has been done or not ....

Shoot it.. if there is no roll of metal around the indent, then who cares, it doesn't need it.

I know that when Greg Tannel does a bushing job that he uses a procedure that makes the firing pin captured. While everyone here seems to be worrying about the primer flowing I wanted a more consistent firing pin hit and not the standard Remington rattle around in a funnel approach. To me that is more important than being able to make hotter loads work.

^ well played sir

I had two pins bushed for 6BRs as they blew primers on even light loads. My smith didn't grind/ turn the pin down so it not being .062" doesn't mean it's not done. Unless you plan on shooting a small primer, high pressure round it won't make any difference.

Tell me ebb...

Have you ever actually taken a Remington 700 bolt apart???

Reason I asked, is that I have taken so many apart, so many times, that I wouldn't even try to guess...
... and there is a M-700 bolt apart on my bench right now (as I type this), and there is no "standard Remington rattle around in a funnel approach.".

The Remington firing pin is held prisoner in the bolt bore by the pin stop/spring retainer - which is a ring in the front of the pin which is bore diameter, less a few thousandths.... it is impossible for the pin to rattle anywhere - it moves straight into the pin hole.

So, PLEASE tell us about your personal experiences with Remington M-700 firing pins - inquiring minds want to know.

I just bushed a bolt on a 722, did the work myself. This was to clean up a pitted bolt face and improve firing pin travel, because even with the firing pin boss riding inside the bolt, it takes two points to make a linear plane. There is enough slop on that boss to let it shift around in the bolt .

I think they make them better now than they did in the 1950's...

thats why all mine have delron bushings had it done years ago!

nope, in fact I would say the parts have more slop in them now . 700 parts are basically interchangeable with 722/721 parts, minus the extractor

None of my R700 bolts are "bushed" and funny thing. Every round goes off, accuracy is superb, so I just shoot. Get a very slight amount of "false cratering" due to the chamfer Remington put on the pin hole but I have het to "blank" a primer. One of my 700's has almost 12k rounds through it with more than a few hot loads but no "blanking".

Who knows, maybe I'll just join the crowd and send the bolts off to Greg to be bushed. Or maybe not.

Catshooter before you go all internet guru crazy on me. Go to the Gre-tan site or go to Youtube and watch the video of what he does to bush a firing pin. He has a cut away bolt and no mater how many bolts you've taken a part you could never know what is going on inside where you cant see. If you watch the video and don't agree with me I will tell the world you know more about guns and Remingtons than Mike Walker did. You will not believe this is common knowledge. Most gun smiths buy there fixtures and tools from this guy, he has invented some of the procedures that are common today.

 

[CatShooter]

There are many that do not have the problems you seem to be plagued with.

And I hate to tell you this, but Gre-Tan's video has some slight of hand in it - he is manually tilting the firing pin to make it look like there is a problem - to do that demonstration without Madison avenue slight of hand, he would have to have the entire pin reassembled without the spring and threaded back into the bolt, and then manually slide the pin back and forth... but if he did that, the pin could not tilt down as he showed...

... and there would be no problem. HE did a bushing for me a few years back, and I would not do it again.
