Looking for mix input please

[Snafu12]

I am new to this. In the past I just cast strait clip on WW for handguns
Looking for mix input please.
Also what temp to run at while doing this?
What order to add each ?
Flux? When and what to use?

I have available
Fluxed and cleaned WW 1/3 clip on and 2/3 stick on (All zinc was sorted out before smelt )
4 lbs of super hard
1 lbs of Tin
I want to use all super hard in this run
I am looking for mix for 303/30-06 boolits and some hot 357s

Will I be able to water quench this mix?

Thanks

For your 357, air cooled ww will work fine.

For 30-06 I use gas checked water dropped WW in a 200 gr bullet. I have good luck.

I have about 100 lbs of tin on my bench, and recently sold off 75 lbs of linotype. I just haven't found any advantage yet to more than 1% tin and 3% antimony. I suppose if I wanted air cooled bullets that were harder than 12 I would want that.

Since you have an abundance of stick on, I would mix 36 lbs of stick on with 4 lbs of super hard and 8 oz of tin. This will give you about the same as WW and will quench well.

Just use the clip on WW's straight up with about 2oz. Sn in a 10 lb. mix, water dropped, will be close to 18 Bhn. Or 16 oz. Super Hard, 2 oz. Sn, and 142 oz. stick on WW's to make a 10 lb. mix. This will give you a 95.75%Pb/3%Sb/1.25%Sn mix. Air cooled to 11-12 Bhn. According to Roto Metals formula. Bhn= 8.6+(.29xSn)+(.92xSb) Should behave like WW's with 3% Sb when quenched.

Fluxed and cleaned WW 1/3 clip on and 2/3 stick on mixed (All zinc was sorted out before smelt )

So my Base smelt is soft

So with the below ratio
Or 16 oz. Super Hard, 2 oz. Sn, and 142 oz. stick on WW's to make a 10 lb. mix. This will give you a 95.75%Pb/3%Sb/1.25%Sn mix. Air cooled to 11-12 Bhn

What temp should I melt at
What order do I add
I was thinking
Super hard
Then slowly add WW
Last Tin
And FLux?

Do you fix in the middle or wait till the end?

[Wireman134]

I'd start the mix at around 700F, add half the Pb WW's, flux a bit to clean, add the tin, flux and mix well, add the Super Hard, flux and mix well. Cleaning the dross off every time you flux. Add the remaining Pb WW's flux and mix well. I place the alloy in the middle of the mix to aid in dispersant. I use paraffin and saw dust to flux.

Jim,
this looks like a good recipe. Your melt strategy also looks good.

I'd mix it up, flux and pour. I'd heat it up enough to melt, not too hot.

I'd water quench.

I've seen somewhere that stick on WW has up to 0.5% Tin in there. Can anybody confirm this?
