Thanks guys, I appreciate the comments.
I like the idea of using round ball because it's the bare minimum of lead possible sot can stretch out my supply. But I also really like the concept behind Big Lube bullets. Being able to have more lube going down the pipe makes me thing it has to make fouling a bit less.
I found out on their web site that you can order a sample pack of bullets for $15 and pally that to buying a mold if you do it within 30 days. I just might do that to try them out.
