Build up of Lead in Mold Cavity

[dangitgriff]

Glad it worked for you, thanks for your reply. I also use the wide pencils on the flats and sharpen the standard to a fine point to get into the bands. Not only does graphite eliminate sticking bullets and most of the small lead deposits, the fine graphite rubbed into the grain of the iron leaves a smoother bullet surface. Not to mention no oil contamination in the cavities. It works on iron, brass or aluminum blocks.

The graphite powder works okay to lubricate under the sprue plate, but I haven't found anything better on the flats and inside the cavities than using a pencil; the pressure of rubbing it in just bonds and lasts longer. The graphite spray also works well; I find it very useful when sprayed on the ingot molds when melting range lead.

Thanks for sharing that, I do not cast yet and read these tips closely.
With cast boolit makers like Rainier closing down, I better get on it sooner rather than later.

If you are serious about getting into casting then get into powder coating your bullets.

I had a friend who showed me how to do that about a year and a half ago...the late, great Jim McBride, a.k.a. myflatline, a.k.a. jimcollc here on cast boolits.
We had plans to get together and cast a stockpile, as I don’t have the room to set it up where I live...but it will now have to wait.

Got into my busy season but I figured I would check in.
The problem turned out to be operator error.
I had carefully, but not carefully enough, drilled out the orifice plate.
Apparently the drill was too large and it ruined the plate.
Ordered a new orifice plate from Magma and the splashing went away.
Such a simple fix.
