I have a nice sxs sidelock double that has what appears to be very tight inletting. Over time the gun has developed two tiny cracks in the middle of the stock immediately behind the sidelock on each side. they are about 1/4-1/2 inch long, don't appear to be deep, but they are visable. What can be done about this problem? My local gunsmith who is a rifle builder, but has limited experience with doubles doesn't think that they are worth worrying about. He told me that they probably won't get any longer, as the wood is very tight grained in that area.He seems to think that the problem wasn't from shooting but from changes in humidity. Any suggestions? And if one thinks they should be repaired, who would you recommend to do the repair work.
