Hopefully, that title will get some curiosity

Read something, somewhere on this internet thing we all love so much about "spoonbilling" or "dimpling" the tips (or actually just to the side of the "tip") of bullets by hand. This supposedly has little affect on accuracy (if itself is done consistently) and will cause the bullet to tumble inside the animal. Also read about filling .22 hollowpoints with vasoline to make what I assume is a crude ballistic tip. Anyone have experience or further information about this? On a scale of 1-10 my curiosity is about a 12.
