Thanks Sparky! It has been a fun challenge that's for sure. I made several springs before I got the firing pin pressure good enough. I'm using .029 music wire which equates to aprox. 3.8 in/lbs. I also milled a flat on the firing pin shaft and used a grub screw in the retainer to pin the clocking of the firing pin. In this way I was able to dress the end of the firing pin for maximum penetration. I'm currently finishing up the extractors now. Hopefully I'll be able to test these out in the next couple weeks.
