The benchrest guys like lighter fluid for their triggers, but remember that their triggers have a very light pull ( 3 oz. or less). Sear contact pressures are very light due to the multiple lever designs and engagemensts are only a few thou. in many cases. Lubricants are less important than dirt free conditions. Flushing the trigger housing with lighter fluid cleans out any dirt and dries completely leaving nothing behind.
Hunting rifle triggers can function lube free, but benefit from something like Breakfree-CLP, etc. for a consistent pull and some rust protection.
