I agree with Skeeter. There are several excellent aftermarket triggers out there. However, I have worked on at least 20 of my own Walker triggers (721. 722, 700)over the years with excellent results. Since most of these were hunting triggers, I seldom set pulls at much less than 3 lbs. But, I have worked my target/varmint triggers to considerably less than that. The one caveat is that when adjusted to light weights, it is important to keep the trigger internals very clean so that the connector can operate freely.
