The problem I see with resetting single triggers, as with shortstroked bolt-actions, is the possible shock of it stopping the shooter from thinking quickly or straight. Although I have handled shortstrokes OK when shooting at deer, I'm not sure I would if a lion were galloping towards me. From this point of view, I'd prefer to hunt dangerous game with a reliable, well cleaned semi-auto than a bolt-action rifle, if legal.

That's heresy, I know, but the mechanism has no nerves. As long as it is clean it is probably less likely to malfunction than a skittish shooter.

By analogy, I'd rather trust whatever complications may be in a 'mechanical' single trigger than hope to tap the butt or reset a selector when TSHTF.
