I've used the .338 quite a bit, using various bullets from 200 to 275 grains. My experience is that the 225 Partition doesn't significantly deeper than the 210 Partition--and the 200 Ballistic Tip penetrates almost as much as the 210.
Have said this before, but the longer I've used the .338 (since the late 80's) the more I've come to the conclusion that 200-210 grain bullets are most effective for most game. They shoot flatter, kick less and kill quicker than heavier bullets.
The bigger bullets might be better choices for really big game that weighs well over 1000 pounds. Then again, maybe not. I've taken both Alaskan moose and African eland with the .338 with heavier bullets, and could have killed either with a 210 Partition just as easily.
