For whitetails, you can load it down with 200 gr FTX bullets. From my milk jug tests, they expand with good penetration up to around 2000 fps. That's 1,775 ft/lbs energy and a TKO rating of 25 which is the same TKO as a .300 Win Mag.
Another good choice at half the price for bullets than the 200 FTX is the 225 FTX. It is also optimized for 2000 fps, yielding 2,000 ft/lbs energy and a TKO of 29.
In CXP2 game like whitetails, they're perfect. Since it's taking forever to get my loads in the database, if you reload I can PM you some good recipes that deliver both the 200 and the 225 at 1900 fps at 100 yds with great accuracy. If you don't reload, the Hornady 250 FTX is currently the only choice for loaded ammo. At 100 yards, it's traveling around 1900 fps yielding 2,000 ft/lbs energy and a TKO of 30. Remington has been promising their version for quite some time.
I bought mine specifically for whitetails in thick wood and brush. Can't wait until November to see it in action.
