I don't see the single set trigger being of any value or at all desirable in a hunting rifle. May be desirable for bench rest shooting. The way it works is, once you set the trigger by pushing it forward in then releases by pulling with very slight pressure, i.e. a few onces. Sako & Tikka single stage triggers are fully adjustable for your preferred pull weight which in a hunting rifle would probably be 3 to 3 1/2 lbs. gg.
