Thats sort of a generalized assumption. Me personally, I shoot TSX bullets exclusively in my handloads. I absolutely love them. But, thats not to knock the Partition, because its a fantastic bullet as well.

I think the one bullet that I have seen shoot well out of more guns than any other is the Sierra Game King. Its a great little bullet, but I personally would not use it out of a .270 on large game. The jacket is a little too thin, and with the speeds created by a .270, it might be prone to cratering a bit much.

Since you are shooting a .270, which is pretty fast, and will be using it on some plus sized animals, I would go with the TSX. Hard to find a tougher expandable bullet on the market. In that same class I'd put the Swift A-Frames (which is basically a bonded, solid base NP) and the Sciroccos (which is a tougher Accubond). All three are pricey compared to the other market offerings, but if there is one place to spend the extra money when it comes to hunting is on the bullets and/or the scope.
