Given that we have endless discussion of what caliber is the best handgun for Alaska and what caliber has enough power/penetration for bears I did a little googling and came up with some comparable info. One of the problems is that finding a standard medium and comparing data from the same medium is needed to have any meaningful data. Comparing ballistic gel,milk jugs and phone books doesn't work. Notice that there is some rifle ammo mixed in in the first page as a reference. I think most will find some results as you would expect and some results that will shock you. For those that don't know the man behind theses tests is John Linebaugh who makes custom revolvers. He has designed some of the rounds listed also.
The second link is a persons test with a 10mm since many people argue about the round. I think it shows some amazing penetration and reinforces for me that it has some serious potential. By the way I did not post the actual page here since it is copyrighted.
Let the wars begin
