I read somewhere recently that per Berger, The VLDs tend to penetrate 2-3" then expand violently and is why they recommend ribshots, not heavy bone busting with these bullets.
...and sure enough, that was my experience last year when I shot a cow elk at 175 yds with 7mm 180 Berger VLD in the left (quartering towards)shoulder. The bullet hit the bone and separated, about a third of it traveled between the hide and ribcage down the left side. The main portion did it's job and punched through the bone,traveled through the vitals and with the wound channel stopping just inside the opposite shoulder. Although it stopped the elk and only went 20' or so, the bullet disintegrated into almost a fine powder. Looked like fine dust all throughout the wound channel, couldn't find any solid remnants of the bullet other than tiny shards of jacket material that were lodged between the hide/ribcage.
