In casting any material, venting of the mold cavity is vitally important!  Our process uses a precision-ground clearance between the mold half faces, which is self cleaning and has no chance of clogging like traditional vents.  This is one of the elements which makes our molds cast such consistent bullets.

Extra care in deburring the entire mold is a very-time consuming operation.  This is where most mold manufacturers "drop the ball."  But here is where the difference is made: blocks maintain alignment longer and bullets drop free more easily.
