Drums can sometimes warp when they are hot and then hit cold water. So if you were driving and using the brakes quite a bit and had them pretty hot, then hit one drum with a puddle of water, Instant pull, and it would not always just go away after some driving time.. I am sure you have tried this but if not, maybe consider taking the drums to the machine shop and have them take a little cut from them, just to square them up, as noted above. Then take the shoes off and put them up against the drum and see what the contact pattern is. They should both be equally not in contact (just the ends, this is where years ago you would arc them to get full contact) ) or equally in contact.
