I have been away form casting for several years and don't remember a lot about what's acceptable in cast boolits. I tried today and most formed well but I have a few that looked like they had cracks or seams in the lead. Just to try and reacquaint myself with the process I also weighed most of my effort; nearly all were within + or - 1/2 grain or the others. However, there were a few that weighed much less than the desired weight.
What guidelines should I use to reject cast boolits aside from the obvious ill formed boolits? I was using the Accurate 312170J (dropping 171 grain) mold and an A.C.E. 312466 (dropping 159 grain).
