OH, I tried to flatten the base of a bullet the way you described, Hoot, and since I don't have a lathe I learned a way not to do it. I put it in pliers and tried to grind it off. The grinder, as you probably guessed, tossed that sucker across the barn. I would have liked to know the velocity of it.
Chuck it in a variable speed hand drill and gently kiss the grinding wheel with it rotating at low speed, say 60 rpm. Try to keep it squared up as best you can. Don't "horse it". A little dab will do ya'
