I'm a big time Hornady bullet fan. I use them ALMOST exclusively. As far as their factory ammo, I have heard very good reports on consistency from box to box. Their "American Whitetail" line of ammo is reasonably priced and the cartridges are loaded with the Interlock bullet which is an OUTSTANDING bullet. Never had one fail me yet on anything from Hogs to Moose! As far as your particular rifle goes, for what you are intending to hunt (up to and including Elk) I wouldn't go under the 165gr bullets myself. Sure you can drop an Elk with 150's. I've dropped them in their tracks with 139gr Interlocks from a 7mm.08 but why hamper the performance of the cartridge? Try out a box of the 165gr BTSP (boat tail spire point) http://www.hornady.com/store/30-06-S...d-165-gr-BTSP/
ANd then a box of 180gr American Whitetail loaded up with FBSP (flat base spire point) http://www.hornady.com/store/30-06-S...can-Whitetail/

See which ones give you the best accuracy from your rifle. If neither, then you are the unlucky owner of a picky rifle of which I have a few. They can be hair pullers. People ask me why I have had a crew cut for 60+ years. I tell them I am a precision rifle shooter..Ask any PRS and they will tell you the first thing you want to do is cut yer hair short so you don't pull it all out
