Default Brinell hardness for 9mm bullets

I've been thinking about trying some cast bullets in my 9mm. I'm not really familiar with how hard they should be for an auto loader. I was looking at some hardcast bullets on GB and they were described as having a Brinell hardness of 18. Is that sufficient?
