[QUOTE="royinidaho, post: 174621, member: 2011"] Jay, Its as I figured, I think. The screw bottomed out before the head came in contact with the mount. That's a bummer of a way to find out. Just to make sure can you dig around with a dental tool or tooth pick and see if you can find the bottom of the hole just to make sure it doesn't already come through. However, I never heard of as screw twisting off well down into the threads. Its usually happens right at the head?????? RE: Jim Hall. Know nothing about his work. The real problem is getting the remaining portion of the screw out of the hole. The remaining portion will be fairly tight, hence the twist off. I don't know if an easy out can be had that small. Talk to Ski(John) at Ski's he may give a recommendation on Jim. Another candidate, who does good work, but is slower that Moses' goat, i.e., you may get it back before next season, maybe, is the fella in Rexburg, across the street from BMC. Bruce something or an other. He's done some barrel exchanging and brake installation for me and has done an outstanding job but it took 10 months when originally 10 days were promised.:mad: If I were in your situation I'd send it to Kirby. He's pretty nice about those kinds of things. Any "good" machinist could do the job. but everything needs to be lined up perfectly to "drill out" the remain portion without damaging existing threads. I also don't know if there is any harm in completing the hole????? It would depend if it is behind the barrel shank threads. Regarding three tight screws and one loose screw: I doubt this would cause your accuracy problems. Regarding bedding: I'd check it with a dial indicator mounted on the barrel and the indicator riding on the forearm. Alternately loosen and tighten both mounting screws. If movement is excessive then you may have found your problem. If it appears a problem then I'd pillar and skim bed. You could do this yourself with a little coaching, just for confidence, and you would be in control of the schedule. Roy [/QUOTE]
