Nice work, but I can guarantee you that you will pierce the primers on the .223 rounds. The standard SKS firing pin is HUGE and the diameter needs to be reduced along with the firing pin hole on the bolt needs to be sleeved

thought the same that it will need firing pin bushed ,but it seems ok with it as is ,just ugly
gathered up a few random out of the snow
did not try hunting ammo but I think those may/will have issues
just wanted something to go through the metal cased cheap ammo I have on hand that was supposed to be used in AR

Nice! I thought they’d be pierced/blown for sure. I know the guy that did the 5.45 conversion had problems with pierced/blown primers, and I also had that problem when I converted an SKS to 7.62nato haha
