Those little pots were made to melt pure lead & probably run HOT
But not neccassarily a bad thing , I have molds I cast at 810f & never frosted the first bullet.
If you have found a routine & pace to pour good bullets with consistent weight/size then sir your setup is working !!
Now that CASTING has your full attention & your becoming addicted more each time ya pour 1 I`d recommend a Lee 20# pot to be minumum & a good thermometer to help keep things regulated
