Greetings again.
I didn't see a "troubleshooting" forum, so I thought this would be a good spot for this post.
I was negatively impressed with my casting this week (about 20 months since my last session), and was looking for some feedback. Now, I only cast roundball for my flintlock and a double barrel percussion shotgun, so my questions refer to casting roundball.
My first few sessions casting (2005) were marred by very poor results: swirls and “smileys” on the finished roundball. I realized I missed a step by not “pre heating” the mold, and when I did this the next session, I got quite excellent results.. So, after cleaning out the Lee electric melting pot this week ( my, “I goofed” thread), I cast about 110 roundball. I only kept about 30 of these, and even some of those were not to my standard as well. Just too many smiley’, or swirls, and on a few, little pit marks. I’m only following the instructions that came with the mold, and it seems I’m following them, but something is amiss. Could the lead be too hot, too cool, should I let the lead set up for more then just a few seconds in the mold? When I see the lead “change” from liquid to solid, I get it out of the mold.
Anyway, if you front stuffers who cast roundball have come across these flaws in your casting, please let me know what I’m doing wrong. I appreciate all your help, comments, (and even a few shots for rookie mistakes ).
Thanks!
