Please, no debates on the necessity of crimping. My Question. After I trim cases to spec. And seat the bullet up to the crimping groove. The COL isn't close to any I've seen anywhere. I'm not compressing my powder and I'm not afraid to fire these rounds. I just wonder if others have noticed these differences in COL's?

The COL is for the max you can go....the ones I do...also fall short of the COL....compare them to your factory shells...should be fairly close....use the same style and weight bullet....I go with a 2" case length and call it good...hope this helps...Oh and I crimp too...

Well Edge has more experience than I, but I use the same bullets for my Zombie/plinking/surplus rounds.....using federal brass...IMR powder....changing my load though....last batch sucked...anyway...my case length is at..
case length....1.9995
COL....2.6965
So I think you are good to go...depending on what you are reloading for....just my .25 worth...and you are welcome...

If you are measuring with calipers from the base of the cartridge to the tip of the bullet, then you are fine. The norm is 2.80" for the .308.
Since you are using a bullet with a canelure, I would continue to seat the bullet to that canelure. Especially if these are just plinking/general shooting rounds.
If you want more accuracy, then you can experiment with bullet placement. Get an overall case length guage and use it to measure your rifles freebore. From there you will know exactly how long your freebore is and then seat your bullets .02" to whatever off the lands and grooves. Some bullets like a long jump, some do not. You just have to experiment with it.
The 150 gr bullets aren't generally noted as "accuracy" bullets. You'll want to try some match grade 155, 168, or 175 gr.
