Try a different scope and see what results you get if they both has the same issues then you know it will be the gun. I love styers this is my 5th lg110 and now I have a 2014 lg110ft and it gose through the Same hole at 50 yards. On the previous lg110 I did get flyers. And 15yerds it's still important for your rifle to be accurate, at hft comp people do miss the close targets (like me lol) like the others said do a group at 30 40 50 yerds and see what results you get. If you still having accuracy issues change the pellets.
Good luck bud I hope you get it sorted.
