Umarex Fusion 2 & 9:00 fliers

I'm having an issue with 9:00 fliers with my Umarex Fusion 2. I've tried 3 different brands of pellets, all different weights and each of them are giving the same results. I'm shooting from a bipod and although there was a bit of a breeze, it's coming from the left of the target, not the right. The rifle is stock, running a brand new 88g CO2 cylinder. It doesn't appear to be related to the magazine.

Has anyone got an idea what the problem might be?

Does it happen as a pattern? Like it's the 3rd shot from the magazine each time there's a flyer? Because the rest of the central group looks pretty tight assuming you held at same POA each time.

No apparent pattern regarding the magazines that comes to mind. I know I was using 2 different magazine. Next time, I'll pay closer attention to that. Yes, same POA with each shot.

Cheers!
