Try taking a look at this article http://www.greent.com/40Page/ammo/40/180gr.htm which basically is prophetic. When I began shooting my .40 S&W last year everything was loaded with 180 Gr... now it is customary to find those same load using the 165 Gr bullets.
I hope your friend is carefully tayloring his loads with the 200 gr bullets.
