If the lead is hardening in the injection point before the mold is full, then heat the mold. Dont go to or past the melting temp for the obvious reason that it wont harden any time fast. I guess you could also expand the diameter of the injection hole with a bore drill. If you do heat the mold, dont pick it up.
yeah i do all that. cant bore the hole out on the melting pot cause it shoots to much in and dosent fill the jig properly.if i was using standard doit molds it wouldn't be a prob but with the pro molds the poring hole is much smaller to make end cleaning easyer so only can use soft lead.
