Like everything else in life, there are trade-offs.
Nosler doesn't list a 200g Semi-Spitzer but they do list a 200g Spitzer, so I used it for calculations.
Using 7500ft altitude and zeroed for MPBR (Maximum point Blank Range) for a 6" diameter target:
500 yards
Bullet, Zero/MPBR, Drop, Velocity/Energy
168g TTSX = 242/286, 036.3", 2109fps/1660fpe
180g Partition = 236/278, -38.4", 2055fps/1688fpe
200g Partition = 227/268. -43.6", 1975fps/1731fpe
I don't see any bad choices there but I would lean towards the TTSX, and in fact have used that in my .30-06s.
With the advent of the175g Barnes LRX BT, though, I might lean toward it. Assuming a MV of 2750fps:
500 Yards
175g LRX BT = 239/282, -38.8", 2114fps/1737fpe
This would give you a tad more energy than the 200g, a tad more velocity than the 168g and a trajectory only 2" different than the 168g.
I've never recovered a Barnes X, MRX or TTSX. One 180g MRX traveled lengthwise through mule deer and exited at about 350-400 yards and another at 400 yards put a cow elk down very quickly after passing through on a broadside. I would expect the LRX BT to perform the same.
