Ok so I just did a bushing job on my savage bolt head. I used a 10-32 socket head cap screw, turned head down to 6mm thread milled the bolt head counterbored it .05 deep for .0005 press Screwed it in with RED locktight. perfect tight fit with .05 (of the screw head that was turned down) in the counterbore. I did drill and ream the hole in the screw in the mill while I had it at work to make sure I was in the center of the screw. Turned the firing pin down to .0615 about .0015 fit to the drilled and reamed hole. Reset firing pin protrusion .040 put all back together. Then thought what am i forgetting and realized the bushing sealed off the gas port through the side of the head. So I guess I better take it back apart and drill or interpolate the hole back in there at least a smaller hole to center breakthrough? Right?
