Thread: When to re optimize seating depth ?

Are people running a new seating depth ladder from time to time ?

Do you measure distance to lands (CBTO) and retrial seating depth steps when it burns out longer ?

Would you routinely retrial for each new projectile type you change to ?

Is anyone monitoring the bullet base to ogive lengths to see if they vary from batch to batch or over years ?

Any other criteria like just every year or two ?
