Every throat is going to be a bit different so seating depths will vary from rifle to rifle. Barrel lengths will make a big difference as far as powder loads go if you are looking for consistent velocities.
I shoot the same bullets in two of my guns and have found the optimal depth off the lands with the same bullet is consistent in both rifles. However the same powder charge that gives great ES's and SD's in one is terrible in the other rifle. One is a short barreled tactical the other a long barreled F class gun
Pet loads can get you in the ballpark but for optimum performance they will still need fine tuning
