Mine leaks a tiny little bit. I put a sheet of paper under it. I once weighed the powder after 150 rounds with Bull's Eye. The total was less than 2 grains on the paper. If you do not like the leaking then you are more likely than not going to have to buy another measure. Be ready to spend even the cheaper ones are still not all that cheap. (At least not for a poor working janitor like me.)
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
