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.
