This is my understanding of why you find the right powder charge 1st and 2ndarily work on seating depth....
The way it was es'splained to me... The powder charge determines the velocity of the bullet in relation to the harmonics of the barrel. The right velocity bullet will sync well with the barrel harmonics to produce a consistent pattern down range. Barrels essentially move in a sine wave pattern when the round is fired. The wrong velocity bullet will fight agains thte bbls inherent sine wave... And open your group's up at distance. There is probably a better way to explain that, but that's the gist of.
Once you have found your load then you fine tune with seating depth. I've tried this. It works.
