RCBS Pro-Melt Pot

[Mose]

Does anybody know about the RCBS Pro-Melt Pot?
This thing is $250 and is really supposed to get the
lead hot. Nah, with the thermostat wide open just as
it gets to 820* it kicks out.... back in about 810*.
Its supposed to maintain at least 850*.
Is there a secret adjustment?
It is a nice looking pot and doesn't leak at the spout
like the Lee.  Any help appreciated.

Thanks,

Mose

Over the last thirty plus years I've probably owned 15 plus furnaces.  I finally sold them all and just kept my RCBS.  Actually I have three RCBS furnaces, one for each alloy I use.

RCBS sets the upper limit of the temperature their furnace can reach so as to minimize your chances of getting lead posioning.  I'm sure about that.  I also sure that I've cast so many bullets over the years that I still managed to get a slight case of lead posioning.  Not really a big deal but worth avoiding if you can.

In all the hundreds of thousands of bullets that I've cast I never found the upper limit of the RCBS furnace to be a problem.

Sounds like it needs recalibrated. This is free just call them and send it back. i have one that is almost 20 yrs old and they rebuilt it and put on a new pot free.

Why cast that Hot? My magma 40lb will go 785deg however I never have had to cast above 710deg. This is with WW +2% tin. I dont see the need for a pot that should go 800 +.  the cooler you can run the less vapor exposure you are dealing with along with less dross and frosty bullets.  However I cast heavy 44cal and up to 50cal so less alloy temp is not a problem with these big cavitys. Small calibers do require a little more heat. I would just cast a faster rythm to keep blocks up to temp. you wont go wrong with the RCBS pot. They are an excellent pot.

Thanks ya'll, I called RCBS and they sent a new thermostadt.
Got purty boolets again.

Glad it worked out for you!! I think RCBS is great to deal with.

                                     Take care!

This tread interest me as I'm ofter asked which is the better pot, RCBS or Lyman. I do have a question. With what alloy and which bullet are you casting that needs a melt that hot?

Creeker, I am casting my own design in a .451 470 gr. GC Ml boolet
for a White .451 Muzzel Loader. http://home.alltel.net/jmose/BigBoolet.jpg
 I use pure lead with 1.25% tin. With
the hi temps I use I get good edges on the lube grooves and consistent
weights. If it's too cool the edges on the lube grooves start to round off
and the weight starts to drop off. I an quite wary of lead poisoning so I built
a vent hood that RCBS pot is in to avoid any fumes. I segregate boolets
after sizing and applying the gas check and have no problem filling boxes
of 50 with boolets that are +/- 1/2 gr. IE a 1 gr. window for a box.
After that I run them through my Lyman sizer again to lube.
With alloys that have more tin and or antimony and other stuff do not
need so high a temp but for my boolets the high temp seems to work best.
If you are interested in my vent sys send me an e-mail.

Bullets look good. Have you thought of increasing your tin to 2%? This works with most designs and will add very little hardness. Long bullets with multiple lube grooves can be a pain at times.

We use a vent system also. One over the machine and one over the 40 pound Magma pots. Really helps when fluxing.

Most our casting with the standard alloy can be done at 700 to 750. We are planning to cast some standard weight Keiths from 1-20 alloy and I'm sure the temp will have to be adjusted.

I'm sending an email. We'll be happy to look at your vent system.
