The problem with what your asking us is what your nail can or cannot scratch is different than what my nail can or cannot scratch. If your looking for a cheap way to determine hardness use pencils. I believe there is a sticky on this.

I am a big fan of the try-in-see method. Cast up 25 or so and load them and see if they work. If they fit they will work fine about 80% of the time.
