I have a 2014 FT my friend has a 2014 Hunter, mine prefers express his exacts.
We had the same problems
We have found the barrel needs cleaning every 200 pellets Max.
If your shooting from a benchrest set up, if there is the slightest movement anywhere it flicks the pellets all over, it must be rigid, check in your scope if it has a big zoom and you will see at a high meg very slight movement and it causes pellet spray/flip whatever you want to call it.
To shoot pellet on pellet takes a perfect setup, at 55- 75 yards.
