TSX is the only barnes I have found to be worth the hype. They are not near as finnicky as the reg x bullet,shoot extremely well, don't foul as much and work as advertised in terms of game performance. While the Partition is still the bullet which all others are measured against the barnes has the ability to be loaded down in gr size without comprimise and still hawg highretention for pentetration purposes even when fired at faster MV's. IMHO the TSX has to be one of the best big game bullets (elk and up) available today. I've used the TSX for a couple years now and have been tickled by its performance on elk and moose. Though I still switch for deer sized game to the NBT's as it has proven to be a great bullet for this application over many years and harvested animals. While others have also worked I see no reason not to use the highly accurate and affordable BT's for my paper/deer sized use.
