Barnes TSX's are great bullets. After I realized the STW was overkill for where I was hunting at the time, since my furthest shot was 250-275 yards. I bought a 7mm RemMag. For the 7RM, I shot the Federal P7RK ammo, with was factory loaded with a Barnes 160 TSX's that were XLC coated, back before I started reloading. They quit making them about a decade ago, but I still have a few boxes stashed in my safe.
The Barnes are excellent bullets, but they don't have a very high BC, and are not really a factor in the LR shooting game, because of that fact. If they would get with the times and produce a VLD style bullet that was solid copper, that would be one hell of a long range bullet.
If you want close and LR capabilities for your STW, the best I've found that doesn't tear up alot of meat, but knocks them dead in their tracks (literally had that happen this past year), was shooting my 7mm RemMag pushing Berger 168 VLD's around 3,000 fps. It is bad medicine for whitetails.
