You asked about the time needed for a casting session. I have an AccurateMold 5 cavity mold and turn out about 300 rounds an hour.
I've got four different Lee molds, two in .45 and two in 9mm. I've tried their tumble lube and conventional lube boolits but could never get them to work out well. Finally I went to the Accurate Mold website (www.accuratemolds.com
) where you can order any design and diameter .45 boolit mold you like in aluminum, brass or steel. Their molds work great, cast at the requested diameter (unlike Lee which can be quite variable) and work without sizing which eliminates a messy and time-consuming step. Take a look at their website and read the info at castboolits.com on slugging a barrel so you order the right diameter mold. Good luck.
