I have read several test results over the last 30 years or so that document that bullet tip damage has little to do with accuracy. Of all the variables in reloading: case capacity, uniform case length, bullet pull, bullet diameter and weight, bullet base, powder choice and charge weight, primer choice and uniform seating depth, flash hole diameter, seating distance from rifling leade plus a few others - IMHO bullet tip deformation is at the bottom of the list relating to accuracy. I am not a good enough shooter to tell the difference.
If it is a concern, shoot match hollow points or Ballistic Tip or other plastic tip bullets. A perfect tip on every bullet can't hurt.
