HI GUYS:
We used to cast and reload commercialy....
First question what is your alloy, hardness is not an indication of a trouble free (no leading) bullet.
The best alloy we arrived at over the years was 85% lead, 2%tin 13% antimony....
We used to reload about 3.5 to 4 million rds of .38spcl every year, plus a large number of bullets sold to reloaders.
As for the lubricant, this was given to me by the folks at Magna, 50/50 parifin and raw bees wax....
Melt your raw beeswax and filter through cheesecloth....
This is a very hard lube, your sizer needs to be heated....
Suggest the Magna lubricater/Sizer, fantastic production machine, with the feed bowl we could average well over 5,000 bullets per hour....
To avoid having your bullets stick together and aid in feeding through automatic machinery (Camdex etc) sprinkle a bit of talk on the bullets after they come out of the sizer, makes them slick and helps keep the leading to almost nothing....
We used the same process on all bullets we produced, .38s, .44s, .45s....
If I can offer any help drop me a note
