BRNO CZ .22LR scoping problem?

I have a BRNO CZ .22LR, my problem is I can’t seem to zero my scope. I was having problems with my Richter Optik RF6-24x50AOE scope, so bought a new scope which is a Hawke Nite-eye 6-24×50 AO SR12, and I’m having the same problem. I get it to zero at 75 yards and a shot or two later its out again by about 3″ Can anyone help me with this?
The mounts are securly fastened, I’m using extended mounts so that the objective dosen’t hit the rifle. I tried zeroing at an indoor rifle club I go to, so wind isn’t a factor.

What model CZ is it? The 452 series takes a European .22 mount.
Are you using CZ mounts? They both are large scopes are they mounted securely? Does the objective end hit the rifle? CZ is a very good rifle,something is wrong with the way the scopes are mounted or it was a windy day. .22lr will drift a lot even in a light breeze.
