Round #3
Started with a flatness check, all with in spec. and very flat and true.
Preheated mould to the max of my thermometer 570F.
knew better but had to try to cast with it.
Filled cavities and started to wait for the sprue to set up.
1 1/2 min. latter still waiting.
Note to self - Real good indicator blocks are way to hot.
Opened mould and nose of bullet was still soft.
Got frosty bullet this time!
Let blocks cool back down to room temp and checked for flatness.
Again with in spec. and very flat and true.
Had to clean the pins (some lead was clinging to them) from casting with it hot but
was able to use 000 steel wool.
Started to cast with a cold mould, no preheat.
First pour was almost usable, by 4th or 5th was getting good fill out and with mould
blocks up to about 280F was getting great bullets.
I feel at this time I can with confidence offer our guarantee on RG4 cavity moulds.
Will give the shop the go ahead to get the buy back in the "Q"
As soon as I get some feedback from them I will post a update.

We will use our standard size 4 cavity blocks 1 1/2"x1 1/2"x3 1/2"
We have .360" listed on the drawing.
Once again thanks to you all for putting up with me.
