Stick on WW alloy – SOWW – Mould fill out

Sometime back when I first ran into SOWW and read the thread on sorting WW on CB forum I just tossed all the SO together smelted and cast ingots.  Been a LOT of years since I had to obtain more WW.

Bought a LEE hardness tester.

Got around to testing the mixed SOWW ingots B4 I was going to cast some BP REAL.  Not only did it go to around 12 BHN it took it several weeks to more or less stabilize just like regular WW. ???

Got out the dikes and started test cutting SO and found the fancy ones were close to regular WW I’d been using for years and the flat ugly ones were dead soft like CB thread indicated.  Need pictures of different SOWW? – I posted some and comments on the CB thread http://castboolits.gunloads.com/showthread.php?139839-Guide-to-Hand-Sorting-Wheel-Weights/page7.

That one batch of mixed SOWW ingots has been sitting around several years and I finally decided to cast a few 41 Keith from them.

My PID controller was acting up a bit so meld temp (my programming errors) was low around 700 instead of the 750 I had planned to try ? right / wrong for temp?

First try on new mould.  Mould was not smoked but nothing stuck.  Washed in Dawn and 4ea 400F cycles run in my TT convection oven.  Ran to hot enough that bullets would tear if mould was opened upside down toward the end.  Slowed casting for a cooler mould.  Didn’t put a temp probe on the mould. :-[  Alloy temp displayed on PID – thermocouple sensor.

Once I found there was a difference in SOWW the hards go with regular WW and soft with dead soft.

Don’t plan of ever making that alloy again even if I had any idea of ratio soft to hard SOWW.

Just wondered if anyone has used just mixed SOWW for casting and the results as to mould fill out?
