fishMOlakes,
Welcome to the Forum; I see this is only your second post.
Since you are new to bullet casting, I wonder why you are starting out with 6-cavity moulds? What calibers are those moulds? Cold temperatures outside are not as much concern as wind. I use a windbreak of a "V" shaped piece of plywood placed upwind of my Coleman Stove.
I have single, double and 4-cavity moulds and think the 4-cavity are a challenge after 40 years of using them. I suggest you start by reading the Lyman Cast Bullet Handbook and then starting with a single or double cavity mould and get the technique down pat before running 6-cavity gang moulds. It takes a long time to fill a 6-cavity mould. Your alloy may not be hot enough. Are all your bullets wringled or just the last in line on the gang mould?
Again, welcome to the site.
Adam
