I have 3 different HP molds , 2 SC Lymans a 358156 with a 1/8" pin , a 357446 with a 3/16 pin , & a 2rg NOE
The SCs like 750f-775f while the NOE enjoys 800f-810f .
I know there`s variables in the inquerry such as casting speed & different alloys.
But what`s the temp most are casting there HPs at ????
I usually warm the pot to 800f get a good fluxing on the alloys then cover with kitty litter to hold heat loss to a min ,then start dialing down with the SC .
