I have been loading 200 grain for a 45acp. I've been using ww's and running the temp from about 625 to 750 and no matter the temp the bullets come out frosty. At about 650 they look nice and bright for about 30 or so seconds then they turn frosty. These ww's were given to me but there is some oil and grease on them. Could this be the problem?

i don't worry about frosted looking bullets,,,,,, as long as they are all filled out and the right size and weight the target isn't going to know the difference unless he sees your bullets...... kinda hard to tell if they frosted or not at 1235 ft per second ............................

Couldn't agree more.

Did you melt down and clean the wheelweights before casting bullets?

I melted and than put some walnut sawdust in and mixed and cleaned. Than I used candle wax twice cleaning between. I do skim off when there gets to be a scum while casting.

257, that "scum" on top of the melt could be the tin coming to the surface. When I see that dull looking "scum" come up it's time to flux again.

I'll try that and see what happens. Thanks for the reply's. Tony

Heat your bullet mold.

Your alloy is a bit warm or your casting a bit fast. If you have two molds cast with both. Fill one set aside, fill the other, set aside while you dump the bullet out of the first and refill.
This will slow down the speed you cast with each mold. eliminates the frosty look.
Frosty bullets shoot just fine by the way.

I don't think it the oil & grease on the wheel weights that is giving you the problem.

My guess would be that some of the wheel weights you used contain Zinc, and the batch is contaminated.

That being said, if they size and shoot okay... who cares?

If you are using an aluminum mould, I will bet the mouldxis getting too hot. Is it taking longer for the sprue to freeze the longer you cast?

I'm learning a lot about casting. I was casting to fast and the mould was getting to hot. It sure isn't just dumping melted lead in a mould and getting good bullets. Thanks everyone for your help

When I am casting I now use two pots and several molds.

When one molds gets two hot I use another one back and forth after a couple of hours I have a lot of bullets.

I have a ventilator beside the tray i dump my bullets in.
That way i get some forced cooling of the mould and can keep up my pace. I can do close to 400 bullets/hour with a two banger.
