    First, I'm assuming that the usual L461 or A1 in, say, .222 Rem. has the No. 4 trigger. Is there anything to be gained by installing a lighter weight-of-pull spring in this trigger? I ask because I've done this many times with my Anschutz rimfires and have been able to reduce the pull weight down to about 10 oz. with the lightest spring available for this (from J & P Custom Products).

    Typically, if adjusting the WOP adjustment screw doesn't reduce the pull sufficiently then it is necessary to carefully hone the internal sear surfaces of the trigger. This is not a job for an amateur. And not even for gunsmiths unfamiliar with this type of trigger. Short of finding a competent gunsmith to rework the trigger, it is likely that you can achieve a 2 to 2.5 pound trigger pull with a Timney replacement.

    When you say "222 Vixen" what model Sako do you mean? The L46 with the Win Model 70 type trigger or the L461 with the Sako #4 trigger will have different adjustment techniques & limits. 222 Vixen, tells us very little about what trigger you have. I've never had or worked on a Sako with a 4 lb pull or one that couldn't be adjusted to an acceptable level for hunting purposes.

    Sounds like something is gummed up. Try soaking the entire trigger assembly in solvent (naphtha or similar) and drying it thoroughly before remounting it.

    Will shoot it again before getting a Timney
