I have several moulds from him, and they are all exactly what I ordered and top quality. I like the self design feature a lot, and being able to see what it is going to look like before I order.
Some guns, like my little .27 Hornet, have to have a custom mould. Nobody makes an off the shelf 90gr. LFN style plain base mould to throw a .278" bullet. Not a problem with Mountain Molds!
