NOE HP moulds are a bit too fussy for my tastes. I only own one MP mould, it works okay, but I'm probably not buying any more HP moulds except for mycollectionaccumulation. I just about have my HP drilling setup figured out, and it'll save all sorts of aggravation in the long run.
It's very hard to get a drilled hollow point to perform as well as a cast one in my opinion. Most of them are straight holes or at the most two angled. The only way I've found to make a hollow point besides casting them is to swage them. If you figured a setup that really works more power to you.
