Remington firing pin guidance

[Addley]

Should the front of the Remington 700 firing pin be guided by the front of the pin going through the bolt face? If so the length of the tip doesn’t even have 0.250” of length. It is just pulling back into space and the collar of the firing pin stop is keeping the pin “centered.” Am I missing something or is this an odd design?

No, not by the original design. Should it be? Maybe, it works as is but consistent ignition may be improved if modified to support the pin tip. If it's a general hunting or field rifle then carry on as is. It'll work just fine.

I was looking for a blueprint….the cutaway bolt in the video was great. I see Brian Blake’s new action has a good guidance system. Likely others. I just purchased a Borden BRMDX. I will have to take a look at the pin.

Thanks for the response.

Good video.

Nice write-up by Jim Borden. Okay I have the bug to blueprint this old Remington action. By the time I get my lathe up and going and get an action jig, mandrel, bushings, tool holder and get my machining skills up to speed I would be better off throwing the action away and buying a BAT action…..but I wouldn’t learn anything!

Cortina Borden interview. Lots of back history on Remington action design and improvements.

Cortina & Borden Interview

This is one of the better Cortina videos. Mr. Borden really explains and shares a lot. I learned quite a bit from the video. Thanks to Eric for doing these.

Theres pros and cons to how you guide the front of the pin. The Remington non guided design doesnt work bad. Thats how Kelbly actions are. The pro to that design is that its less prone to binding caused by production issues. I do prefer a guided pin because I believe its a little more consistent but in practice you do see more bound up, which is why we go through every one.

If you assemble the bolt sans spring and move the pin back and forth within the range that it normally cycles, looking directly at the front of the bolt as if you were looking down the hole in the bolt face, you should be able to see if the tip of the firing pin drops down as it moves back in the hole beyond where the tip fits. I believe that the issue is the fit of the FP flange in the bolt, and the potential for bind comes from the fact that the bolt body is two piece. A while back I did this test on a recent 700 SA and it passed with flying colors.

Years ago, curious as to whether my early Viper action's FP assembly was rubbing inside the bolt I removed the assembly and completely marked up the outside of the spring, edge of the flange and pin in front of it with a large navy blue marker. After a trip to the range I took the bolt apart looking for spots where the color had been rubbed off. There were none. Like most custom actions the firing pin hole and tip are configured to guide the pin throughout its full normal cycle.

Most of the time there will be a shiny spot at 6 o'clock on the tapered section up front. A good indication it's rubbing and bouncing.
