I have an old Auto 5, a kind of family heirloom, that went duck hunting with Ernest Hemingway some time in the 1920s with my grandfather on the Missouri River, if family lore is to be believed. I want to make it a viable gun for modern use, but my understanding is that the old steel barrels can't take the modern waterfowl shot loads because the steel or tungsten will tear up the old barrel. It shoots lead buckshot just fine, as well as lead trap loads.
Questions - 1. is it true that the old barrel can't take the modern loads, and 2. if so, I assume I can just get a replacement barrel for duck hunting?
