If you removed the barreled action from the stock (say, to adjust the Accu-Trigger), be sure you re-installed it using the proper procedure:

Drop the barreled action into the stock.

Start the action screws just far enough to catch threads; be sure you have the screws properly oriented (they are not the same length).

Holding the barreled action in the stock with your left hand, lift the rifle out of the rifle vice (or rest) so that the muzzle is pointing up and the butt plate is on the bench.

Apply moderate pressure on the barrel so as to force it aft (toward the butt plate).

Tighten the front action screw to about 30 in-lb.

Tighten the rear action screw to about 20 in-lb.

Now check that the barrel is free floating, and then check that the tang is free floating. Savage usually does a good job floating the barrel, but it is not uncommon that some relief of the stock may be needed to fully float the tang.

If you have to remove the barreled action to open either the barrel channel or the tang relief, re-install using the above procedure.
