It dont necessarily has to do with your bedding job, it is all in the harmonics. Deepening on how tight your action is to the stock/bedding it will affect the gun harmonics. If the gun harmonics change your accuracy will change (improve or worse). I have read in an article or two that you at times can improve a good load by working your action screws. Needless to say, be careful if you do so, stripped action screws are upsetting but stripped action screw holes are upsetting and expensive!
