ok i shoot CZ75-B 9mm 147gr plated with 4.7gr of unique and now i switch to 125gr lead with 4.5gr of unique and im shooting alot lower . When i was using the 147gr the bullet hit where the sights were pointed id like to have the same with the 125gr.
shooting low

As you probably know the 125 grain bullet is going faster than the 147 so it is exiting the barrel sooner.
This means the pistol has had less time to recoil and the bullet impacts lower on the target.
To adjust this reduce the powder charge making sure you don't go below minimums and the action cycles reliably - you may need to try a different powder.

as in #3 , mv is the thing here , your 147 is running @ ? , load 124 to the the same speed & you'll most likely have the same poa/poi , or change the front sight . 147's are usally a bit better for accuracy & knock down for steel . a lot of those cz's hit high with your 147 load , has the front sight been changed .
