Raider,
I have several Lee 6 cavity molds. Only two of their molds have been hard to get to work well. Both of them have been the 45 caliber round nose versions. The one I mentioned above and their 228gr RN in 6 cavity. It casts big and that makes chambering difficult.

I also have a bunch of H&G molds and would rather use a 4 cavity one of those than a 6 cavity Lee. I get better bullets faster.

The H&G aren't cheap by any stretch of the imagination, but they are the best, at least in my opinion. I would like to get one of their #34 or #16 molds.

FWIW
