I'm not a gunwriter but I do use the 120gr Nosler BT and 120gr Sierra Pro Hunter in my 7mm08 - both are very accurate but the Sierra is substantially cheaper down here at the bottom of the world.
I have used the Sierra's on Wallabies (quite possibly "overgunned"). They dropped on the spot and the damage was very significant. In the future I plan on using the Sierras for practice and general plinking and the BTs for game (deer, chamois and tahr).
