Remember, this is just an Ol'Coot's opinion, but one who has been casting/reloading since the 60s.
I personally do not like lead pots, #1 I didn't have good luck casting with them, - lots of folk do - but more importantly is they are slow!!!!!!!
For handguns, I like to have a casting partner if possible and run about 5 - 2 to 6 cavity molds at a time.
Simply put, the electric pots most people buy, will not come anywhere close to keeping up with the volumin of metal I go through.
I do not cast for fun as I would do with reloading, so want to maximize production when I set up to cast.
Using a large lead pot over an old Colman gas stove AND a Rowell bottom pour ladle is the best and fastest I have ever used.
Now, Casting for my 45/70 is a differant thing, as groups size at 100yds or beyond is important. There, I still stay with the pot and ladle, but but the rate of casting is slacked way back.
Keep em coming!
