Pressure pour? Is the pressure generated by the weight of the molten lead or do you pressurize with an external source? 

boats - Just called the 'antimony man' and found out he is ill and taking no orders. The person who answered stated that it would be 'some time' before they were, if ever.

Also, why does one need an ingot mold? Does one need to empty the pot and not let the lead solidify in it?

Anyone ordered from Rotometals? They have the Rowell ladles and also sell 20-to-1 lead with free shipping.

SSS,

  Before you get too confused with helpful advice I'll give mine.
Get a Lee 20# pot and a RCBS dipper and learn to use that. It will be hard to do better.

SSS,
For lead, go to the local scrap yard and look for sheet lead or lead pipe. Then go to the hardware store and buy (no acid or resin) 50/50 solder. You will have (by weight) 50% tin and 50% lead. 

Use 9 lb of lead (144 oz) add 14.4 oz of 50/50 solder (7.2 lead and 7.2 tin). You then have a mixture of 21/1 lead to tin. 151.2 lead / 7.2 tin = 21 to 1. Nothing has be exact. Your shooting won't be affected if you use 7.5 oz of tin instead of 7.2 or if you have a few more ounces of lead. But, that is the way it's calculated.

In my opinion it is easier to learn to cast good consistent bullets with the dipper method than with a bottom pour pot. Once you learn how hot your metal wants to be to fill out the mould well (nice sharp edges, no whiskers) then work on a casting rhythm so that the weight stays consistent. For about a 200 grain .32 you should be able to stay with in .3 tenths of a grain once you get the mould up to casting temps.

SSShooter,
I think you made a good choice. I have made many thousands of very good bullets with bottom pour pots (RCBS - 2 of them).  I have found that the dipper works better for larger bullets (.45 - 400+ grs.) though.

With some molds I drop pour, holding the mold an inch or so below the spout. With others, I do make spout contact....typically with .30 and less caliber molds.

I do leave alloy in my pots all the time. The only time I empty them is if I am changing alloys.  Make sure that you read the pot instructions about not running the pot below a certain level. I refill if the level gets down to 1" or so.  Otherwise, you can burn out the eating element prematurily.  Been there, done that.

Have fun,

Bigger is better keeps the lead temp more consistent. Too big is hard to handle with small molds.

My 2 cents worth

If I were going to buy a pot now I'd get one from Fergison (the antimony man) It is as good an electric pot as is available. The design has a nice wide lip so you can place your mould on it and heat it up as your lead is melting. About a 20# capacity.
