With the velocity that the 7mm STW generates, you need to look toward controlled expansing bullets. Such as, Nosler Partition, Trophy Bonded bear claw, Swift A-Frame and the Barnes-X. I have had good results with the Partition and the Barnes in my 7mm Weatherby Mag. The STW will produce higher velocity. The Nosler Ballistic Tip is very accurate but the possibility of bullet failure is high if your game is up close. I have two acquintances that I see at the shooting range from time to time that own STW' s. Both of them have the best accuracy with the Nosler Partition. They both also choose the 160 gr as their all around load. By this I mean deer & elk.
