Barnes tsx or Bergers

[nube]

I shoot a 7mm stw with 140 gr tsx. I am interested if anyone has done any tests comparing bergers and tsx at long range? Which one has the higher BC and would fly flatter at long ranges? I here a lot of good things about Bergers but haven't talked to anyone that has proof if they are better to use or not.
Thanks

Basically most deer bullets are made for minimal expansion so most will do about the same. The berger will retain better energy and velocity. I quit useing tsx because of the $$$.
