Cycling a bolt, even in an awkward “Has never fired a gun before way” would only take a couple seconds. I’d be in favor of having a “manual cycle” delay based on the shooters rifle skill, to reflect that as you get used to shooting a rifle, you can cycle the bolt incredibly fast, to the point where it’s barely a second, much less a full six. With this, bolt actions would become a good option for skilled shooters, while inexperienced operators would still have reason to seek out automatic firearms.
