I?ve never had an issue with any of my BFRs and I don?t run any of them lightly. That said, I don?t think the .500 Linebaughs have had problems as only a handful have been built and the one I have is the first and I?ve ridden it hard since day one without issues. I don?t think BFRs are as susceptible to ERH problems as Rugers, but installing a deadman isn?t a bad piece of insurance!
