Dumb question I know, but did you clean the barrel really well before you started shooting?
Were you shooting open sights or a scope?
Just a suggeston but start shooting @ 25 yards - shoot a group and see what you get....
The new Savage I got the other day came with scope blocks installed - I then installed the scope was bore sighting and could not keep it on spot... Took the scope off and the blocks were loose...With open sights often the front blade does not fit as tight as it should.
In shipping a lot of things can work loose...
Just some things to think about...
FG is not going to like your Winchester report, but them again you probably do not either...
Good luck getting it more ready for the next trip...
