I have some 170 gr Hornady SSTs but as I said, I have no experience yet with the 8 on elk.
At .323 and 170 grains I am sure even a poorly designed bullet would be OK on deer or Pronghorns, but elk are big and sometimes pretty tough, and they have big hard bones. I sectioned one of these bullets and the jacket looks pretty thin.

So I am specifically asking for advice on the 8MM Mauser on elk if any one has experience. Elk or any other game of 600 pounds or more.
I have read some posts saying such-and-such .323" bullet was made for the 8MM Magnum so it won't expand on game from the 8X57, but every one of them has been written from a standpoint of theory. So I am asking for real-world experience if any of you kind folks can tell me
