Skipping Preheating Mold?

[JonB_in_Glencoe]

"Is it possible without detriment to a steel or iron mold to just start pouring bullets?" YES

"I know they will come out wrinkled at first but could I do this for a few bullets on my Lyman without warping the mold?" YES

I like to preheat all my molds now, so I can open the sprue plate with a gloved hand, and NOT have to Beat on it, with a mallet...which I have done, when pouring alloy into a cold Iron mold. Also, It's nice to get good boolits after the first 1 or 2 or 3 pours...instead of 25 or 30 pours, to get the mold up to temp.

And a lot of people used 1-2 cavity moulds for many years, but I don't choose to if I don't have to. Just makes life easier using some new technology.

I cast my first bullet over 50 years ago and it was out of a iron pot on a Coleman camp stove. I have to say I am thankful for the new technology like my RCBS Pro-Melt, Noe Thermometer, induction hot plate, Brownells Marvelflux, etc. But the fact is my old H&G and Saeco Molds don't produce any better quality bullets, it is just that now I can do them with less effort and faster.

Pre heating the moulds does have it's benefits, but when I start a casting session, I usually place the moulds on the top of the pot while it's melting the lead. When the lead has melted, take the mould and throw 3-4 casts and from my experience, the mould is pre heated and starts throwing good boolits. When you have to put more lead in the pot, put the mould(s) back on the top of the pot and they stay nice and toasty. Well, that's the way I've been doing it for a while, just my experiences
