I caution folks to not remove too much pre-travel on triggers, especially on new rifles. Wear it in a bit before adjusting it, or it could suddenly turn dangerous.
Triggers with rough pre-travel should be smoothed by a competent gunsmith. I personally like a bit of smooth pre-travel in rifles used for offhand shooting, since it helps to be more conscious about smooth pressure and follow-through. I'm not a trained smallbore target shooter, but can hold my own in informal competitions and am recognized as being a very good plinking and game shot.
In handgun shooting, I prefer shooting revolvers double-action, provided the pull has been smoothed and lightened.
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
