I would say that there are a couple of three molds from MP, NOE, and possibly if you want to spend the money, Hollow Point Mold Service, that are about as good as you can get. I know that you can get a couple of different bullet designs from each as well. The thing about HPMS is that he takes a mold you have already purchased and then turns it into a HP version. It is just about as cheap to simply get one already made into that configuration.
Do a little shopping on the NOE site, and then check out the MP versions over on Castboolits in the Group Buy section. You might look in the Closed Buys and in the Results sections as well. You really cannot go wrong with either of these.
