Cheap Way To Add Weight

[lajry]

About 15 years ago bought 25 lb of #9 buckshot for $25.00. Use white glue to keep it put in my freight cars. Still have about 5 lb left. Even gave a few lbs to my MR friends. Wonder if it's still being sold given that lead is considered to be such a hazmat these days. And if not what are hunters using for a substitute?
