I used to file the points off 6.5x55mm 139gn FMJ ammo with no downside I could find.
Later I also drilled holes into them.
I don't recall the size but maybe around 3mm was all, and about 10mm deep.
I have no idea how effective they were as I only shot foxes with them at that time, but they didn't lose any accuracy.
