The mold is not hot enough. The first ones cast will show wrinkles, as the mold heats the rejects taper off. Once the mold is hot enough, pour and wait maybe 5-6-7 seconds and drop. By waiting to drop there is heat transfer from the molten lead/tin to the mold. Once you get the proper cadence down you should be able to cast 200 nice bullets before fatigue sets in. I only use iron moulds, they hold heat longer. Good luck!
Mold was all the way up to 450F. Lead was up to 850. I will try again tomarrow. I will win!
450 is your problem.
Started at 350 as per NOE instructions then raised to 450 when nothing else worked. I turned on the hot plate at the same time I turned on the lead pot like I always do. In the time it takes 25 pounds of lead to reach temperature the mold was hot. Both lead pot and hot plate are fairly new and both have been tested for temperature. I played around a wide spectrum of techniques of pouring from slow to pressure.
I guess that is part of the fun of casting.
