Author Topic: Casting Temp ? (Read 780 times)

Hi, I've got a question for you guys. When casting, will a hotter or cooler lead temperature have an effect on the size of the bullet? I am using wheel weights and was hoping to cast some bullets on the larger side.
Thanks,
Dennis

bullets cast quickly enough to frost will usually be smaller so try reducing the heat and see what happens.

both hot and cool temps have an effect on diameter and weight! usually staying at a certain temp will give more consistent weights. being all the way up (hot) has its advantages but for certain lenghts of time. to find a happy medium start at 700 deg. and see how the mould takes to this! this also depends on what caliber your shooting, and the mould,, the smaller the caliber the less frost you have to contend with. but eventually you will have to deal with it so let the mould have time to cool and then adjust your heat if necessary. good luck and have fun

To restate what's been said in a little different way, both mould temperature and alloy temperature affect diameter.

Therefore, build a rythm and note the alloy temperature, check the results, make notes. Change ONE of the variables, note the effects. You'll soon become the expert.

Some folks will use maximum temperature to cast, a sponge to cool the sprue plate and cast as fast as possible. Another common technique is to use two moulds, letting the mould cool while filling the second.

Take notes. Paper brains retain the information much better over the years.

I like the temp on the high side and use two or more molds to keep the mold temp consistent.
