I used to have a 10# Lee pot, but happened onto a good used 20#er at a great price. The difference in getting melted lead is not that much more time in the larger pot. Plus, when you are casting heavy projectiles, 400-500 grains, that smaller pot will empty pretty fast. And yeah, mine leaks sometimes too. Just scrape down the sides and bottom with a thin wooden stick, flux a couple of times, keep a screwdriver handy for twisting the plug rod. I also hung a lead weight on the operating handle and that cut waaaay back on th amounts of drips. Using clean lead is also a good thing.
