![]() ![]() I had a certain, other, Utah-based custom mold maker cut me a 1-cavity brass mold for my own. Material makes you think! Still a lot to learn Now it would be interesting to see if it was the mould block that producedĪ smaller bullet or if it was more to do with the melt. Not the most scientific set up but I found out what I needed with it. Smaller bullets and with this big bullet it was very apparent It was interesting to see verification that hotter moulds do produce This mould made great bullets at 280F to 295FĪt 340F to 360F bullets frosted but still had good fill out. Returned mould to hot plate and repeated at 340F The ten measurements are from that 2 pours Preheated mould to about 280F and cast one pour. The mould was preheated on a electric hot plate The mould block temperature was checked using one of our digital thermometers Pot temperature was 700F, I have our "shop Pot" set at that and keep it there. ![]()
