9mm lead bullet question

[layusn1]

I saw this mold:

And I was wondering if any of you casting gurus have any experience with it.  I saw an example of the expansion it gives in 45

and it looks kind of impressive.  Would that be a hard bullet to cast?  I would be really interested in buying that mold if it is something that a beginner would be able to cast after a little experience and if it would actually produce a bullet that is as good as the one shown in the example in the webpage above.  What do you guys think?
