Why arent there any vents in my mould?
There are! We vent our moulds differently than other mould makers by grinding a clearance between the faces and sometimes a vertical groove along side the cavities to further vent air out of the mould. This process has counted very much toward consistently-round bullets. Normal vent grooves tend to plug up with lead, nullifying their reason for being. Also, the lead feathers from the vents tend to get caught between the faces of the mould, causing an out-of-round bullet. Our process is self cleaning and thus more reliable.
