Thanks for posting the terminal performance pics, they are much more important to a lot more guys than you think. I see no issues with them at all, we are hunting and fact of the mater is it killing an animal and blood and gutts are part of that, making an effective clean kill requires damaging internal organs and that damage is more important than trophy photos or holes in paper, it is where the rubber meet the road when we are talking bullets in a hunting situation!!!
The pics of the 375 hits are really interesting, I've been contemplating a 375 Cheytac in some form but it's hard to get some performance info. That blood shot is really not that horrible, looks like it mainly in the seams which is easily removed. I have pics of an elk that is blood shot about the same amount from a hit with a 140 Accubond which is considerable less bullet, though it's far more blood shot than I've gotten with my 338's with the bullets I've used so far.
