GAMO SAT CAT Adjustment and POI

I replaced the M2.5x6 with a 10mm.

Before doing this, my $100 Black Knight was "zeroed".

Two days of non usage. Only change was trigger screw.

Took it out today. Trigger is much better, BUT the POI at 25 yds had risen almost a foot. And gone right 4 inches.

Would a trigger adjustment on a break barrel cause this? Would it change the "harmonics" of the dual recoil enough to have to rezero?

I am not counting out scope or mount slide.

Thank you all in advance.
