I guess that is a simple summation and it looks really nice.

Mine won't heat above 650. I called RCBS and I have to ship it to them and pony up almost 100 to get it back to spec. Bah. I would fix it myself as it should be a simple parts swap but they chose to rivet everything together. I could drill them out but then I would have to buy a rivet gun to replace them. So far I'm not impressed.

The one serious upgrade I see is the valve has a blunt nail in the end that really plugs the hole. I keep thinking about how hard it would be to have someone mill one into the Lee furnaces as I think that is all that stops the dripping. With either Lee the smallest bit of slag will cause the hole to not seal.

It's secondary but I like the stainless steel bowl. I don't like there isn't a good spot to clip the thermometer. I keep meaning to build a bracket for the thermometer to hang from into the lead. I think they could have done better with the mold guide.

I guess I need to consider myself lucky as I've had two Lee Pro 4-20 pots and they have never had the drip. I've never have figured out why they are called "4-20".

I have no doubt that RCBS will make it right, but the fact they are chargeing you shipping n such bummer. I bought a used ohaus 1010 scale which the patent now belongs to RCBS. I got it at a steal of a price cause the user could not calibrate it. The shot in the pan was missing (the counter weight). I didn't know it till I got it. I contacted rcbs they sent me shot, a new powder pan, and new shot pan. Free of charge no qeustions other than whats your address.

Everything RCBS makes that is electric has a short warranty. Which I guess I get as they don't want to give away coils and thermostats for the next hundred years. I'm just bummed that I pony up for what is supposed to be a better pot and it doesn't work.

I would make a rude joke on Lee's 4-20 being that four pound of every twenty is going to leak out but I know it's my own fault for not keeping the pot clean enough. But it rears its ugly head every so often despite I flux and stir like a madman. I tried the polishing the inside lip of the spout with the valve needle and then I added the high temp anti seize compound and that helped for a while but it didn't seem to stay in place.

I just use too much scrap lead that is just filthy still. I recently started buying more lead from Rotometals and I think I'm only going to use that once I finally run out of scrap.

The nice thing about Rotometal lead is it's a known alloy and already smelted but you pay for it.
