Let's start with the low-budget approach that you can throw away when you get more-better stuff.

1 Qt STAINLESS (not aluminum) sauce pan & a Goodwill one burner hot plate.

An iced tea spoon - for skimming off the crud (and something to put the hot off-scouring into).

A lead-pouring ladle made for the job is important (if for no other reason for safety).

Good set of leather gloves and EYE PROTECTION.

I use a 0-1000dF thermometer from an HVAC supplier and a couple of thermocouple based meters from EBAY.

All kinds of rectangular steel pans for pan lubing from Goodwill, glass is more stable (doesn't flex and dump the bullets over).

There's a start.

The Lee 20lb. Ladle pot is a good choice. Mine is no over 12 years old and still going. You can just about buy two each on sale for the price of one Wagg replacement heating coil. Hook up the Lee to a 1000 watt dimmer switch and it holds the casting temperature real well as there is no cycling on and off as it provides constant amperage to the heating coil. We picked up two 20lb. Lee pots a shot time back for 59.00ea. Get a paddle that marries to the spruce plate, stay away from those that only allow you to pour the alloy in. Some moulds require a little head pressure from the ladle to fill out the bases. Travers has a nice digital thermometer including the probe for less than you will pay for a good casting thermometer and it is money well spent.

Yes to the Lee 20# pot. Do not get the bottom pour pot (any) as they drip. Even the good ones eventually leak.

For great temp control get one of these. With my 325 & 340gr 38cal bullets it holds temp so well that out of 100 bullets the weight variation is under a grain or less than 1/3 of 1%. I segregate into 1/2gr lots, so the variation is around 0.17%.

Does even better with the 40cal bullets.

Also bought a large slotted stainless spoon from eBay for something like $10. Have never figured out the need for flux and ingots and other stuff. Get the lead and your mould to temp, pour nice bullets, occasionally skim dross from the melt, replenish the pot as needed. With your small bullets, that won't be very often. You will find that with a little experience and a quality mould it is very easy. Enjoy!!

It's not how you do it as long as the results are what you are looking for. All the pot does is melt alloy and hopefully maintain temperature. The most expensive pot out there cannot cast good bullets, it's up the operator to provide that function. Alloy to temp is alloy temp and it doesn't matter in the least amount how you get and maintain it there.

After you get the technique down with what you have add a PID controller. You can really dial in the temps and hold them there. It's going to cost in the 200 dollar range but really an improvement when trying to cast quality boolits.

Enjoy yourself casting,
