Slower than
bottom pour but OK with me.
While it would certainly seem that using a bottom pour furnace would be faster, I’ve learned that for me it’s really not. I have both a bottom pour furnace as well as a homemade lead pot (on a Coleman stove) and a ladle. And even with my homemade pot and ladle, I learned that I can easily go
too fast. The molten alloy in the mold has to be given time to cool and solidify before knocking the bullet(s) out of it. Furthermore, the faster I refill the mold with molten alloy, the hotter the mold gets, so the longer the alloy in the mold takes to cool and solidify, and so on and so forth…
I’ve found the way to cast more bullets in less time is to have a
couple of molds going. I fill one mold with molten alloy, set it down, pick up a second mold, fill it, set
it down, pick the first mold back up and knock the now solidified bullet out of it, and refill it.
I usually run two molds at the same time that drop different bullets of the same caliber (like a 44 caliber 225gr SWC-GC and a 44 caliber 250gr SWC), but sometimes I’ll run one mold that drops 38 caliber bullets, and another that drops 44 caliber bullets. Either way, once I get a “rhythm” going with two molds, I can cast a lot of bullets in a short time
without overheating my molds.
