A trigger is the first thing I do with every firearm (pistol, rifle or shot
that I buy. It's also the first thing people notice about my firearms when they shoot them. A crisp 3lb trigger is better than 95% of all rifles out there. I like a little lighter than 3lb's for a long range type rifle, but 3lbs is definitely usable. I have a Timney in my 7RM set at 1lb and it is great. My competition cowboy guns are all set at 1lb with zero creep. It all depends on what you want and what you're using them for.
Although a Timney is FAR from a 'top end' bench trigger, they can be pretty good. My 338AM has a Jewel trigger, but I haven't played with it yet. Many standard Remington triggers can feel very good. I haven't played with the Xpro, however I've heard that with the Xpro, you don't need an after market trigger like a Timney or Jewel for most applications.
