Oregon White Oak from seed

I am curious if anyone has ever planted Oregon white oak from acorns. The past two years I have been randomly spreading acorns around my property on dry open hillsides to try and establish some oak trees. According to my research they are well adapted for dry conditions. I have around 28 inches of annual precipitation and the acorns I use were sourced from an oak forest on the dry east slope of the cascades near Yakima, WA where there is even less annual precipitation, I'm guessing about 20 inches a year. My climate is almost exactly the same as where the seeds were sourced from with very similar associated vegetation such as ponderosa pine and various cool season grasses. I'm thinking my soil may be different though as I am planting in mostly a heavy clay soil. Do you think that would affect them that much? Most of my trees are currently microscopic at 1 and 2 years old. They leaves are very tiny. Even smaller than when they were seedlings. But other than thier small size they seem to be fairly healthy with dark to light green leaves. They are just really puny. I'm almost thinking that they are spending all thier energy on putting down a tap root and maybe in a few years once they have a better root system then they will shoot up but that is just my optimistic theory. Has anyone else ever planted Oregon White Oak acorns in a natural setting with minimal care such as irrigation and got similar results? Will they eventually start to really grow once they are more established?  Or has anybody had this happen with other plant species? Just curious about my puny little trees.

I haven't planted the Oregon white oak, but I have planted acorns from a Shumard oak. A lot of newly sprouted trees, plants, and shrubs will appear to stall in above ground growth as they focus energy on root growth. I've heard, read and also found through my own observations from small trees purchased at a nursery that I planted that trees often have this growth pattern of sleep, creep & leap. Oaks are a very slow growing species and I would not be surprised if your saplings or mine took 10 years to get as tall as a person.
