My Annihilator P.B. fell, won't group now.😭

So I was cluttered and pressed to move the gun when a neighbor appeared mowing next door.  Set it on the porch swing, then bumped the swing moving about.  Tipped over and only the barrel shroud hit the patio.  Rest of the gun was still hangi g off the swing seat.  2 foot tip over if that.  Immediately shot off into the bushes.  Ive verified the scope isnt the issue or the shroud, removed the shroud, rolled true on a table, removed barrel, no crown damage naturally (as its protected in shroud), no pellet clipping I can tell, shot with shroud off, same poor groups as shroud on.  barrel orings looked fine.  It throws a flyer every couple shots and doesn't stack em anymore, very poor groups at 25 yards.  What else can I do?  This was a dead ringer beforehand.  I hate myself.

Check all hardware, first and foremost.  If it shoots different, something shifted.  Then check optics/sights.  Re-zero at 10 yards, then 25, then 50.
