I've been reloading for 20+ years but am new to bullet casting. Recently, I was gifted with a box of used molds, melting pot, and an old RCBS LAM which was missing parts. RCBS was gracious enough to replace the missing parts to get the LAM back in action. After pouring over the threads here, I bought some tubes of Carnauba Blue from WLL. Sounds silly but I settled on the blue because I like the color. Anyhow, I think it is working out fine. I mean, the lube flows without a heater, sticks in the grooves, and looks real pretty and shoots great too. My question is, am I really using the right lube? What is the criteria which determines which lube you should be using? I am mostly casting for 9mm, .38, /45, and 300 AAC. Might someday want to cast and shoot some .308. Pretty much all my casting, lubing, and shooting is done in 50-90 degree weather. I store my finished bullets in my beer fridge so the lube don't melt off. I think I am doing it right but experience has taught me that nothing is ever that easy. Am I missing something? Is there something else I should be using?
