Hi all,
I’m an experienced reloader, but just started casting about a month ago. I have spent countless hours reading on this forum and the information has been invaluable. I have been able to troubleshoot most of the problems I have come across so far, but there are two Boolit imperfections that I just can’t figure out.
First, on the base of my Boolits where I cut the sprue, sometimes I get a nice smooth bottom and sometimes it sucks into the Boolits a little bit. I have tried changing sprue plate tightness, heat (I finally got temp control down), and pour height. The image below shows what I’m trying to explain. Is that a big deal or is it acceptable?
Second, I am sometimes getting rounded driving bands and crimp grooves. I am getting them from the same cavities that will cast a perfect boolit the pour before and pour after. This particular one is an MP 454640. The mould was cleaned correctly when I got it and heat cycled before use.
Thanks in advance for any knowledge bombs about to be dropped.
