I just purchased a 10" 6.5mm TCU and would like to use it for deer hunting at modest ranges. 100yds. and closer. Any thoughts? Pet loads?

The 120 grain Ballistic Tip is the way to go here -- actually, the only way to go in my opinion. ANd for powder, you can do lots worse than H335. You can expect to top out around 2000 fps, and you should have no problems getting sub-MOA with it. Rem 7 1/2s are the primers I favor in this little round that's big on performance.
