The first tip, NEVER put cold lead in a hot pot!
Moisture in/on a cold slug will cause a steam explosion and it's PAINFUL!
Ask me how I know that...
While casting on small volume is slow, it's remarkably satisfying, and a lead mold never goes bad, always good to have.
Several cavity molds speed things up.
There is the 'Old School's way to do things, and the 'Latest-Greatest' ways,
I still smoke my molds with a candle or match, I tried the fancy mold release, didn't really work any better.
I preheat the mold by laying it across the lead pot, no extra steps needed.
I do buy multi-cavity molds with 3 handles, an extra handle for the sprue cutter. It helps a bunch when doing a larger batch.
Hammering on the mold shouldn't be done with a steel hammer.
I use a brass/bronze hammer (a small one), I see internet videos with guys using steel and it dings the molds up, even bending the sprue cutter on the longer molds.
Once the first cast or two is out of the mold, lubrication isn't required normally.
Smoke or lube the first cast and the mold usually releases bullets with just a tap.
If you find fine lines in your cast, looks like a hair got into the mold, your lead is too hot.
Doesn't really effect the bullet, just isn't pretty.
Seriously overheated lead will try to stick in the mold, but it has to be seriously overheated to really stick tight.
My lead pot gave up three months ago, found one on eBay for about $50.
An actual bullet casting pot isn't required, but it's sure handy!
If you want to lube bullets, install gas checks, swage for size, etc. That will take extra equipment and everyone likes something different...
