I decided to try and lap my 358429 mold that was supposed to be fixed by Lyman. I used 320 grit Clover and noticed some lead oozing out between the blocks like part of the bands were coming off. I've only tried this once before and don't think that happened last time. Cause for concern or just a matter of the way it is doing this? I was attempting to not only smooth things out a little for easier drop from the mold and also to increase the band size by at least .001".
