Tonight I went out to the garage for a TempTest-Run
Waage 20# Casting Pot (K-4757)
Lyman #2 (Rotometal)
Standard Lyman Contact Dipper Pour (for me)
Accurate 45-200H (H&G-68) 200gr 45 ACP Dbl-Cavity Mould
Lyman Lead Thermometer
Hot-Plate Mould Preheat during Lead Pot Heat
My standard #2 Lead casting temp is set 720°
All the below occurred as Temp rose to, and past, liquidus/600°
At 600° degrees/all-liquid I stirred in -- repeatedly top to bottom/bottom-to-top -- very large pea-sized piece of 50-50 bullet lube to Flux/Clean
Restabilized at 600° and I began to cast -- steady rate of 5 casts (10 bullets) every two minutes.
First cast keeper and all grouped in growing sets of 10 as the Temp rose to standard 720° for last minute of casting
Quit and allowed all to cool to room temp.
Weighed each group of ten as a group, and divided-by-10:
And since Diameter goes ∝ √weight
Just the raw data then . . . .
Thoughts ?
