I am about to try out casting .22 slugs using Aluminium molds from MP Mold. Just wondering what kind of lubricants should be used for the spruce plate and the alignment pins. Any advises will be appreciated.
Aluminium slug molds - what lubricant to be used ?
- Thread starter airgunfans
- Start date
Most bullet casters use alox bullet lube which is a mix of alox (a particular type of grease made by Alox Corporation) and beeswax. Be sure not to get any residue in the mold cavities or you will have problems. Once the mold is hot use a pin and put a very small amount under the sprue plate pivot, a very small amount on any alignment pins, and just for good measure a bit on the handle hinges. The heat will melt the wax and it will flow to where it is needed.
Proper temp of alloy (or pure lead) and the mold itself is critical to not getting "folds" or frosted bullets which is what happens if t's too cold or hot. What's the right temp you ask... when the bullets come out like you want them, it's a balancing act.
Aluminum molds are the easiest to use, and they are pretty tough so you should be able to smack the handle hinge pin to get them to fall out of the mold. The problem with light bullets is there is not enough mass for them to want to fall out of the molds. Once they get "seasoned" things get easier. Good luck, have fun and as mentioned... be SAFE. Wear safety glasses!!!

This stuff is the best I have ever used
i got this info off the internet on best way to use
Get some full-synthetic two-cycle premix oil, or Bullplate sprue lube formula
Boil the mould blocks and sprue plate in distilled water/detergent solution and rinse.
Wet half the tip of a Q-tip in the oil and wipe the underside of the sprue plate, alignment wedges and pins, and go around the sprue plate pivot bolt head/washer to squeeze some in there.
Take the dry end of the Q-tip and go over everything again to wipe off excess so it doesn't migrate to the cavities when the mould is hot. You can also follow the Bullplate instructions for applying hot with the cavities filled, but an initial application on a cold mould will help prevent mould damage from the beginning.
