I'm relatively new to reloading/handloading . I generally load to the posted COAL (overall length). The spec sheet for 270win with a Nosler 165gr ABLR mentions "seating depth " and "shank seating depth" . I'm assuming "seating depth" is how much of the bullet is in the neck of the case. "Shank seating depth" is foreign to me, I have not come across that wording prior.
Can someone enlighten me? Always willing to learn.

with the shortage of primers can I substitute magnum for Large primers?
There is no risk in trying. Magnum Primers are there to ignite large volumes of powder in Magnum calibers. They ignite powder faster as they have a larger flame. If you substitute with a LR primer, the ignition is slower. This will create lower pressure so there should be not risk.
However, it can have the following negative impacts but you have to try if in your specific case they are relevant. If not, I would continue with LR primers:
Slower powder brun leading to overall lower powder conversion
subsequently to lower muzzle velocitiy
subsequently to lower energy and a different trajectory
can also lead to more incensistant powder brn impacting precission of your loads
BUT AS SAID - no risk in trying.
