It is not so much "scorched", as it is "sooty". As mentioned above, too light of a load will delay the sealing of the chamber and the combustion products begin to blow between the brass and the chamber wall before the brass case seals. It happens mostly in handgun cartridges but does also happen in some too lightly loaded (with slow burning powders), rifle loads also.
