I'm going to make a J type mould to pour lead decoy weights. I see some for sale on E-bay saying they've been heat treated to make the lead hard so it won't bend out of shape. How do I heat treat my weights?? Thanks for any help some one could give me.

Lead will have to have antimony and a trace of arsenic to be heat treatable.Cold quenching a wheel weight alloy will make tham plenty hard.Straight lead cannot be heat treated.

Thanks I'm using wheel weights. Just drop them in cold water from the mould?

Dropping in water from the mold will push an otherwise 10bhn to about 14.4bhn on my lee scale. Just did some last night as a matter of fact.
Your mileage will vary depending on what you started with.

Suggest you have a large bucket of cold water close to where you cast your bullets. I put plenty of old rags in the bucket as well to keep the bullet from slamming to the bottom of the bucket. Don't know if the bullets would deform without the rags, but I do it anyway.

I usually use a 5 gallon bucket and fill the bucket about 3/4 the way (about 8" from the lip of the bucket to the water level) and I found that placing a cushion on the bottom is not necessary. The idea of filling the bucket with that much water is to increase the distance from the top of the water to the bottom. This gives the bullet enough time to solidify before it reaches the bottom.

ESOX,
Folks are correct here, I use ice cold water. the colder the faster those bullets are going to cool, the larger the bucket the longer your water will stay cool.
Be careful with water when casting bullets. Don't splash any water in the molten lead, this will cause an eruption of lead out of your pot. Dont get water on your mold either.
You can also heat treat lead alloys in a oven, heat your castings up to 420F for a few hours. dont use your kitchen oven though, some small electric ones will do.

I heat treat cast bullets in the kitchen oven at 475 deg. for 1 hour,remove and quench in ice water in the sink.
They will get harder every day for about 10 days ending up at near BN30 if your alloy will allow such. I use straight WW + 2% tin.
My tester shows them on par with Linotype.

Leave the decoy weight soft, in long strips they can be bent around the decoy neck when the string is wound up and ready to go home. When you stomp them in the sand or mud they will hold and won't straighten out if soft.
I've even used railroad spikes for weights with a hold drilled in the thin tip and a wire loop for the snap to hook on. But I left the spikes at the blind at the end of the day and just sacked up the decoys.
