Unconsisted powder drop

Hello.

I just got my new SDB and it started with problems on my first reloading session.
The problems started when i adjust the amount of powder (took 1 hour to adjust it) my goal was 4,5 gr. i have the DAA turnknob with 1-18 on it, when i finally reached 4,5gr i ran 10 cases with weight and dump powder to be sure.
After 10 cases i weighted again and got 3,8gr, ran a couple cases weight and dump, still 3,8gr. adjusted to 4,5gr and started to weight every case. (did 100 that way) veri unconcisted powder weight, most where 4,4-4,6 gr but suddenly it where of by miles. it looked like this: 4.5, 4.4, 4.4, 3.1, 4,5, 5.2 and so on. My concern is the lowest where 3.1 and highest 5.2 on rounds. Its 2,1 gr in difference, dangerous!!!! I need to be at least 4,3 to get PF=126 (ipsc). and 5,2gr gives to much pressure for my gun. Anyone got any ideas?

Powder: Vihtavuori N330
Cases: GECO once fired 9mm
Primer: Fiocchi SP
Bullet: CMJ 124gr RN 9mm
