You should look at getting a production pot and click here for a great source for bullet alloys. Otherwise watch out for those pesky surveillance cameras in the Walmart parking when collecting wheel weights! ;-)
Thanks for the link to the metals source. Always great to have a backup in case the free source runs out!
We don't shove these bullets too hard because of rules and also because wheelweights wouldn't work so good then (or we'd have to put gas checks on 'em). And the targets are real close so you don't need a lot of oomph. Some people in the club download until the bullets barely roll out of the barrel, but shooting .38 instead of my usual .45 ACP I don't even notice the recoil with fairly standard loads. We did switch to Clays from Unique because as much as I love that powder it's FILTHY and after 6 stages of around 25 rounds each we have 4 firearms each to clean!
