I know what the safety is for, but what's the non safety trigger for. I never chamber a round until I'm ready to shoot something and really have no need for a safety.
Target rifles, mostly. There's a certain purity and simplicity in the rifle that is either loaded, ready and pointed downrange, or empty, open and with a empty chamber indicator on display. Nothing in between. In a situation like that a safety is useless and can even be a distraction. In the same circumstance the sure and certain knowledge that your chamber is empty on a closed rifle will still get you kicked out, or at least reamed out by the first person to spot it. One guy's safer than hell is the next guys unforgivingly reckless.
