I am going to guess a heavier bullet has a less "snappy" recoil, along with more bullet being held by case tension, so might be a better choice in a revolver, where a bullet moving forward is more of a concern than in an auto, where a bullet moving backwards can be an issue. Just a guess though, as all my revolvers are chambered for traditional revolver cartridges that use a roll crimp. That said, I have not heard that much about this being a problem. Seems the worst offenders are ultra light revolvers loaded with full power loads and light weight bullets.
