I don't know how much to make of it, but this is a link to a guys website that has done some pretty extensive penetration tests with different bullets in a variety of calibers. Most interesting to me was the result of comparing the 210gr. partition to the 200gr. BT in a .340 Weatherby. The partition retained about 20% more weight, but the BT penetrated over an inch farther!!! Here's a link to the site.
