I am thinking about making my own firing pins, i was planning on just buying .0625 ground drill rod and then also getting .090 drill rod and drilling a hole and pressing the two together and then harden them. any thoughts on that or input on how you made yours?

I'm also going to be using those ejector pins. I think I bought the ones with a .060" OD though (98378A405).
It made more sense to me to go that route rather then make the pins myself. Once you figure out how long you will spend making the pins yourself the cost of the ejector pins makes more sense.

In my opinion both of these designs need changes.
By using the multiple +/- .005 tolerances to achieve the goal
the rim could be missed completely.
Not good for rim fire.

Gary,
Definitely not to .115, that would strike the .281 counter bore.
I would suggest striking the rims edge as close as possible.
That’s where the primer is concentrated.
I used .105 for the 180 bolts I made last year.
Still need good alignment between Carrier and Barrels.
