Yesterday, I was casting some 200 gr 45 SWC with an RCBS mold and 125 gr 358 RNFP with a Lee. Both are 2 cavity molds. What I found was the RCBS produced 100% with no rejects, however, the Lee sometimes threw wrinkled boolits. I know the alloy was good as the 45s were perfect and the Lee was not contaminated since it mostly threw perfect as well. Do you think the alternating technique allowed the Lee to occasionally cool too much? Should I up the lead temp (I was around 700)? Or ditch the alternating when using the Lee?
