Mould fill is related to mould/lead temp. Get a good lead thermometer (RCBS) and bring the mould and lead up to the same temp. I have always found that 750 to 800 is a good temp for good bullets and weight consistency, if the latter is impt to you.. Some people advise heating the mould up by dipping it in the lead pot but I would not/did not do that. It will come up to temp by casting a few bullets.

Be sure to hold the mould handle firmly together or you may get some 'flashing' on the edged of the bullets. No big deal for plinking for for accuracy that will trash your groups at any decent distance.

Good ventilation is a MUST as previously stated.
