Yaaa, I'm planning a Kodiak bear hunt later this year and I decided to resurrect my old childhood sling shot. No primer problems, quiet, efficient and deadly. As for load data, I only have this marble that I found.
Crazy glue could also be used to repair split case necks I bet. Also, I was just brain storming and I think I'm going to stop all re-sizing and start gluing the bullet in the case. I bet the brass life would be extended exponentially!
Every one knows that you can't use super glue for split case necks. That's what JB Weld is for.
