I think that anyone who shoots long - meat or paper - is looking for consistency. There are tools out there for metplat uniforming IIRC and at first blush - it looks like there's no way for it to be consistent.
In reference to Burger, the published BCs are from actual testing of said bullets with unmodified tips. While their values are an average the spread is very small. Litz did some experimenting with metplat trimming and bullet tipping and there were minor increases in published BCs. They shoot fine right out of the box.
