You need to relief the area around the safety. Take a crayon and color in around where the safety is on the inside of the stock, put it on thick. Put the action in the stock and tighten down the screws. The crayon will show you where it is rubbing. It will either be rubbed off or shinny where it is interfering. Take a powered rotary tool and the cut out the offending wood. Use a chisel if you do not have a rotary tool. Go slowly when removing wood. You do not have to remove very much, usually. Take off a little then try the fit. Continue until you have a satisfactory fit. Some times you get one area so it fits and then another area interferes. Do not be afraid, just go slowly. The fit will be OK as long as you do not remove any around the top of the stock or where the bottom of the action rests. If that is where it is binding, then take it off here very carefully so you do not have a large gap. I have found the Boyd's stocks to be very good, but they are semi inletted, so there is some fitting that needs to be done. I do it with out thinking, it is just part of the process. Some times even factory stocks need some fitting to be right. I have bedded several stocks and I remove lots of material before I bed. Good Luck and good shooting.
