The SniperCountry.com web site has a page on how to adjust the trigger of a Savage 110 at http://www.snipercountry.com/trigger.htm
, and it has this important warning:
The trigger (and its face that engages the sear) are sintered (made from powdered metal). This process results in a part that has a very hard, thin outer surface, yet is soft and ductile inside (both these properties are desirable). However, a gunsmith that does not know this may attempt to "stone" or polish this part, in an effort to "clean it up" and reduce friction.
This exposes the soft, underlying metal,
which will cause this part to rapidly wear
(and the soft underlying metal will have higher friction)!
Somebody makes a drop-in aftermarket trigger for the Savage, but at the moment I can't remember who...
