[QUOTE="WildRose, post: 1006657, member: 30902"] BG I want to thank you for your suggestion. I was looking at it like this. "Do I try to save a hundred dollars ad risk ruining a 700.00 action". Well here's an update. After about 3 or 4 hours of work I figured out the problem with the bolt had nothing to do with the outside bearing surfaces I was lapping and everything to do with the internals. Field stripping it is no big deal even without tools and when I did I discovered the firing pin and spring were bone dry filthy, and rusted! Tried cleaning it good with a brush and solvent and then oiling and reinstalling but it was still severely binding and still squeaking just a bit. Repeated the whole process 3 times and it was little better. Not having the right tools to disassemble the firing pin assembly I was hesitant to do so because I hate having to carry a box of parts to someone else to reassemble when I can't so I thought of just taking it again to the GS and letting him figure it out. Well, those who know me well will tell you I'm not one for giving up and somewhat pig headed so of course I decided to muscle it and break it down. What I found was that the firing pin was rough as hell so I stuck it in the drill and used the drill as a lathe and ran it for a good long time with a piece of emery cloth smoothing it down. Following that it was still rough so I put a sanding disk on the dremel and continued turning it with the drill while lightly sanding at the same time. After five or ten minutes it was done and roughly satisfactory for a test run. Worked it quite a bit in the bolt assembly minus the spring and found a few stiff places, broke it back down and repeated. Finally got it good and smooth. Reassembly was a real chore lacking the right spring compressor but having very strong hands I muscled it down and held it with a par of pliers, and actually managed to get it back together and get the pin reinstalled without splattering parts all over the room! Oiled it up and put it together in the bolt body, reinstalled and guess what? Yep it is vastly improved and I'm convinced now that it will eventually wear to a point it runs perfect. That got me thinking of your advice because nothing inspires like success. Not having what I considered to be the right file/files I used the same sanding disk and quickly and easily opened it up enough to get a round through easily the opened it up just a bit more. I will still need to replace the follower to get it to run perfectly but I was able to load two in the mag box and single feed another and then work it to eject 1, and successfully feed and eject 2,3. Repeated four times all working well so I'm going to declare success and go shoot it! Thanks again. [/QUOTE]
