I got into them because of the modularity, ease of changing barrels etc, and the accuracy. I like to tinker and do my own work as much as possible. I have changed shouldered barrels too but it requires more time/work/tools. Not a huge deal but the barrel nut makes it so much easier. They're often not perfect, but usually a little tweaking and maybe some parts changing and they can be made reliable. I have also had other brands that had problems as well, not just Savage.
