I don't know man. I have the same problem and I guess airguns has this problem so we going to have to deal with it. Check your zero every time you go shooting

Hi Guys
I have a problem with FX impact M3
I found that my poi followed a repeatable pattern through the course of a fill
there isn't any contact between the barrel and air tube
barrel cleaned and scope parallax is ok ,scope rail and mount is tight enough and liner is indexed
ES is only 5fps in shoot steering(more than 50 shoots) and 5 shoots group is very tight(8~10 mm in 50m)
but group shift have clockwise pattern start from 12 to 3 then 6 and 9 and last 12 after zero in each of them
any one have a suggestion?

Check the liner. Make sure it is not moving or rotating inside the housing if you have changed your liner, make sure you hand tight the jam nut then give it quarter turn with wrench Don't forget to apply some loctite blue

is the MV changing? I'm thinking unstable pellet yaw as it slows down.
