Wanted to post this somewhere that people would appreciate it. I ran into a guy before I started casting that would come into the club before close, and wait until it closed. It isn't manned, everyone just has a key card. So after shooting hours, he just went and emptied the lead from the backstop. I have made a few trips of that now that I have started casting. My first 4 trips varied in weight from 15-45 lbs. I went shooting again tonight and hung out until close. I wound up filling a 3 gallon bucket. I got just about all of the lead, but not quite everything. I am glad the bucket is only 3 gallons. I thought if I could take any more I'd be tempted to. I am not sure at what point I'd risk hurting myself transporting it, but I am glad I am not tempted to carry more than 3 gallons worth. When I got home I weighed it out to 95 lbs. I imagine my scale probably isn't very accurate adding my weight to the lead at those numbers though.
I am going to work on cleaning and casting this. I would like to maintain a stockpile of bullets worth a could years shooting. But I plan on moving in a couple years. Moving boxes of books is bad enough, I hate to think of moving actual lead.
