Axis Magnum Conversion: Firing Pin Too Short Fix?

[Desnolen68]

Dear Savage Community:
Here's my current attempt on Axis Magnum conversion as I had been slowly collection parts and reading on this subject, especially after reading Dr. Thunder88's "MAxis" post back in 2016.

I ordered the Long Action Magnum Bolt Head from MidwayUSA, savage part# 103960. . Upon receiving it the bolt lug measure a little under half inch, which as compare to the axis bolt lug it is 0.44 inch. In addition, as Dr. Thunder88 had pointed out, alone with a video, the Magnum Bolt Stem is too long and need to grind down to around 1 inch in length.

Last night I finally got around to performed the magnum bolt head's stem shortening. I continue to check back and forth with the Axis firing pin, until I achieve 0.05" protrusion. However, in order to achieve the desire firing pin protrusion, the grinding of the magnum bolt head's stem went under 1" in measurement.


Upon assembly the bolt with the magnum bolt head that been worked on, measurement of the firing pin protrusion is only at 0.025 inch at this point. Turns out the Firing Pin Cocking Pieces has bottom out in the bolt body slot, and prevent the firing pin from making the 0.05 inch desired. Consider the fact that the magnum bolt lug measures at around 0.49 inch thickness, while the Axis bolt lug is only 0.44 inch...

At the moment I am considering this solution to resolve this:
Grind down slightly on the bolt body's slot, where the "cocking piece pin" bottom's out and is currently preventing the firing pin the final travel/protrusion.
My question is would this create other issue if I take out around 0.08 inch and allow the cocking piece pin moves deeper upon firing? I have read that at 0.035 firing pin protrusion is enough...

Please excuse my ignorance on the technical aspects, as I am still rather new on custom works, learning and digesting info, articles, advises while making hands on approach. Sincerely Many Thanks!

How did you determine that the cocking pin is hitting the bottom of the cocking ramp? When the firing pin is in the fired position does it rock back and forth or is it impinged tight against the bottom of the ramp?

If it does rock back and forth easily, I would either pull the cocking piece pin out and remeasure the protrusion or disassemble the bolt and slide the firing pin into the bolt head and check the protrusion while out of the bolt body. Verify the restriction. You are right that under no circumstance should the cocking pin touch the bottom of the ramp as I think you understand. The firing pin stop should slam against the back of the bolt head when fired.

With the fixed length firing pin you have no options. Making the cocking ramp deeper so the pin doesn't bottom out will give you more protrusion, at the same time making it harder to cock.

You could spend that kind of money and chances are it still wouldn't be right. Best way to fix: 86 the one piece firing pin, and use a long action firing pin assembly and cocking sleeve. The firing pin will need to be shortened from the front end about 1/4", and the spring will need to be trimmed to 23 coils. This will leave enough adjustment for protrusion and the cocking piece position. I did this to my Axis, but my camera is busted, so no pics...sorry.
