One caution--DO get that firing pin out! I thought I was slick, and did a mineral spirit soak on everything metal (including the bolt) but could get the *&^%$ retaining pin out to take the firing pin out. Figuring I had it licked, I rinsed the the bolt and metal parts in soapy water/ boiling water rinse, and then baked the bolt in a pie tin in the oven at 300F. As I thought, liquid cosmo just gushed out, even starting a little fire. After, the pin 'clicked' and sounded clean. First time out, everything went well, but the pin snapped while installed in the bolt; the one 'shortcut' I took bit me. Oddly, while unsafe, the rifle still worked fine with the broken pin in place.
