Re: Lead and Zinc?
yep. and once alloyed it is incredibly difficult to separate it.
Keep your pot temp at around 660 degrees and no hotter. Pure lead melts at that temp and all the good metals that make a good lead alloy melt at a lower temp. all the stuff that ruins your mix melts at more than 700 degrees.
So maintain a 650-660 degree pot and flux often. Keep the floaties skimmed off.
I made my own flux when i casted. Home made bullet lube and sawdust, mixed into an even slurry and let set to harden in a pan. Then cut into cubes about 1/2"X1/2"
It takes 43 muscles to frown, 17 to smile, and 3 for proper trigger squeeze.
The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do.
Fact of life:
After Monday and Tuesday, even the calendar says WTF!
