I don't have a 338 now as it became a 340 and that one finally went down the road too. But if using either one I'd jump right to the 210-gr TSX/TTSX and try make it work. These bullets work very well as fast as you can push them and as has often been said, you don't need the weight of the heterogenous bullets. And they are almost invariably accurate.

I probably took 8 or 9 bulls with the 210-gr TSX out of the 340 and out to 500 yards.
