RockTumbler.com has a great video showing what happens inside a rotary tumbler. The clip is only 44 seconds long but it graphically demonstrates what happens if the barrel is too full and if it is not full enough. It’s conclusions are:

Barrel Too Full = No Tumbling Action 

Barrel Not Full Enough = Damaged Stones 

Barrel 1/2 to 2/3 Full = Great Tumbling Action
