Alan:
 
I’ve always attributed thisto the heat and the side to side stress of the filing.  I have noscientific proof but I always questioned the idea of stressing the new pins whenit’s just not necessary.  
 
If you have noticed as youremove old pins from a famous piano factory, many were installed point sidedown, and others round side down.  That’s why they had to file thetops to hide the irregular installation.

Ron,

I, Terry, and a bunch of other folks drill 
bridge pin holes deeper than necessary, and drive the pins in to finish 
height, without filing the tops.

I've noticed (and brought this uppreviously) that pianos with filed bridge pins tend to have looser pins overtime in the environment around here than those that are not filed. (Although this could also be a "pressed-in rather than pounded-in"difference as well.)  Think there is anything to that?

Thanks,

 

Alan Eder

There is no acoustic benefit to having the bridge pins bottomed out. 
Seating pins just means you have seated the strings by the friction 
between the string and pin. I, Terry, and a bunch of other folks drill 
bridge pin holes deeper than necessary, and drive the pins in to finish 
height, without filing the tops. If you try to bottom one of these pins 
in the hole, you'll drive it below the cap surface trying.
