For someone who wants to put together a 1 load, 1 bullet for every thing from deer to elk out of the 30-06. I generally see the 180 partition as highly recommended for elk out of the 30-06. It seems the tsx gets recommended in the 165-168 due to it's mono construction.

How does the 165 partition stack up to the 180? Is the 180 made "tougher" with a thicker partition, or is the only difference the weight, thus it can afford to shed more?

In deer sized animals I'm guessing the 165 might be a better fit, but does anyone have experience with the 165 partition on elk?

As an aside, what real-life range differences (velocity and drop) have those who've worked up 165 and 180 partition loads found?

Thanks,
