I had the same problem today with my NOE 5 cavity HG34 clone . I got mine to putting out good bullets by turning the lead up to 700 and really heating the mold on a hot plate . I'm used to Lyman steel molds and this is a different beast . Run the mold hot and fast with a generous spruce seemed to work for me . When they started to wrinkle I would put it back on the hot plate and grab another mold .
