The max cartridge base / ojive length on my Remington 700 .223 is only .016 more than the SAAMI.

CAOL according to SAAMI = 2.250

Max COAL for mine = 2.266

Does this sound about right? im asking in the context of finding the best seating depth for my rifle, and im wondering if this level of head space is about average?

I have Sammi listed as 2.260", but I run 2.280" in my 223, different rifle., and no idea what bullet you're using, which can also effect OAL.

What are you referring to as 'headspace'?

I have some rifles that run longer than Sammi, and one in particular where if I run Sammi, I can't shut the bolt.

Every rifle is different !
