I am using two pots because I load up around 40-50lbs in the pot. I am not yet casting bullets either but am measuring the hardness of my lead blocks prior to casting to see if anything needs added.

Looking at my stainless pot i'm using it's pretty dirty in the bottom and i'd prefer to do it in two stages. It's personal preference I guess.
What calibers are you going to cast for? If your casting for most non magnum /non gas checked handgun calibers - hardness is not as critical, if you lube properly. Wheel weight alloy is often fine for that case. When you start getting into full power magnum, and rifle calibers then it is. Make sure you read your load data - on the velocity. You'll notice on some calibers like 44 Mag, the load data is showing a lower velocity, to reduce or avoid leading. Alot of times they limit the velocity to 1000FPS to avoid leading. The higher velocity data usally will show a harder alloy like Linotype 2, or a gas check, or both.

If you are fluxing with Clean Cast, be very careful with that stuff. It leaves a hydroscopic goop allover your pot lining, and mixing ladle. It also breaks down the lining of your pot, if you leave it in there long enough. The next time you go to cast, the alloy with explode from the water content on your ladle when you go to stir. I had that happen to me a couple times, and I quit using it. I do not like that stuff one bit. I just use Gulf Wax, which is cheap, and one pack will last you forever.
