I have both a Lee and a Lyman melting pot with spouts on the bottom. The problem is that when I do mold, i make enough so I won't have to do it again for a while. The electric pots cool down to much when new lead is added. I use an old deep side cast iron skillet on a white gas coleman stove. I can melt about 30 pounds at a time, and it doesn't cool off too much from adding a few pounds.
I'll mold 440, 490, 535, 570 and 620 balls, 500 grain 45-70 bullets, 450 grain 50-70 bullets and usually few hundred of each round ball and maybe 150 each of the cartridge rifle bullets. That's over 11 pounds of 45-70 bullets at one session. For several of these, I have 4 cavity gang molds which consume alot of lead in a hurry.
I open the molds just an inch or so over a tin tray which is set on a slight slope so the balls and bullets gently roll down to one end and out of the way.
