Does seating bullets closer, to the lands speed up the process of throat erosion (in general)on rifle barrels? Thanks!

probably not? the bullets going to contact the rifling any way.

Trimming the brass too short will probably do more damage to the throat.

Yeh what cobra said, i think the general concensus is that the higher the pressure the faster the wear.
I think, considering the rifle is still shooting within safe pressure limits (no over pressure signs), you should expect to see the accurate life expectancy of that barrel close to what history depicts.

Re: bullet seating depth vs. barrel life
New barrels are very close to being unobtainium for folks like myself. I am constrained to follow bore conservation strategies in my handloading process.
My approach is to use longer barrels, and download my cartridges to achieve velocities similar to hotter loads in shorter barrels. This is my primary bore conservation strategy.
It would be most helpful to me to find out definitively whether touching or jumping is the better approach from a bore life viewpoint.

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.
