What is the best thing for filling a rear bag for making it as heavy as possible.  I don't shoot competitively, so I can cheat and use things besides sand.  
I was thinking lead shot mixed with sand might be a good option. The only thing is I don't know how crazy I am about sucking on a block of lead while shooting though. I suppose it is contained pretty good inside the Protektor leather, but everything gives you cancer these days in CA - can't be too careful!
Any other ideas?
Thanks!
