I just recently picked up a cz557 3006, it has a 20 in barrel and a 1:10 twist. I bought some factory ammo in 150,165,168,170,175gr. and had terrible results. I loaded some of the brass from the factory ammo with some speer 190g and 185 Berger hunters and my groups shrunk from like 2 inches to 0.80. Seems to like heavier loads. Question is should I try a heavier bullet and if so what do you suggest. Thanks in advance, I just don't have any experience with 3006.

What powders are you using?
i have never loaded for or shot an '06 with a short barrel. You might need to go to a faster burning powder. I load 48gr IMR3031 165gr Nosler Partitions. Not a hot load but it sure performs on Deer and targets. My rifle is a 24" Rem700 from 1969 1:10 twist.

Bullet selection depends on your intended goal(s). Target accuracy? Hunting, and if so for what? Tactical/military? Tell us more and we can make suggestions on bullet selection.

Out of my 30–06 with a 26" hart barrel I use 58 grains of imr4350 , Berger 168 classic hunter bullets , 20 thousands off the lands. .5 MOA.Also it's for deer, or stray pigs

I would not necessarily equate the poor performance of factory ammo with light to medium weight bullets and the much better performance with heavier weight handloads to the rifle liking heavier weight bullets. Handloads often perfrom better especially with berger bullets. For your application, deer and pigs I see no reason to go heavier, if anything I would explore 165s
1) H4350 is a great powder for the 30-06, so stick with that
2) 56-58 grains for a non-monometal bullet and 55-57 for a monometal 165 grain bullet shoots very well in most 30-06s. My experience across 6 different 30-06s.
3) For bullets in the 180-185 range non monometal, I would try in the range of 54.5-56.5 grains
3) Remember max pressure for a 30-06 is only 60K PSI and every modern 30-06 action and piece of brass mfg'd was was built to also be a 270 Winchester at 65K PSI, so don't worry if the best load you find is slightly over book max.
I always load a couple of "safety check" rounds below my starting load.
