I'm glad I load my own Bismuth too. A few years ago I'd been noticing Bismuth shells in odd loads (like 3.5 inch 12 ga... not many vintage guns so chambered) sitting forever on a local retailer's shelves. They finally put the shells on sale at 30% off, and I offered to buy all they had for 70% off. They bit, and I've been cutting open shells and salvaging the bismuth for my own handloads ever since. I enjoy handloading, and now have enough Bismuth to last me the next 20 years for about the same cost as today's premium lead loads.
