I've read here and on other sites and pubs that vertical stringing is minimized when chamber pressures are such that the bullet leaves the barrel at the top or bottom of the barrel travel during the harmonincs of the barrel when fired...hence the significance of ladder tests to find a starting point during load development. All makes sense.
But I've also read that minimizing horizontal stringing is a function of proper bullet seating depth. If this is true, then why is it true?
