the biggest mistake I see with most glass bed jobs is the use of screws..If you tighten the gun down, the chances of putting a bind in the action are pretty good....Use a set of guide screws and let the gun sink to the bottom or were its braced. Drillout the holes, clean it up and your good to go. this is especially true on a full length bedding job such as I do on most really big bores along with second recoil lug in the barrel channel, cross bolts, and a threaded bolt throughthe grip. Also don't forget to pack the front of the second recoil lug with clay or whatever for about 3/4 to an inch depending on the length of the lug, so tha the barrel can come out at an angle are you will have married the stock to the metal. smile
