Re: bullet seating depth vs. barrel life

After a couple hours thinking about the physics, forces, and metalurgy involved; it is my opinion that to a good first order, throat erosion is independent of bullet seating position.
The physics and forces of engraving the bullet on the rifling do change with bullet seating position, but these forces are so low in comparison with the pressure and heat forces of firing to recede into second order (at most) kinds of things.
