I have killed quite a few blacks, with all sorts of weapons. I have seen flip and roll around and then die, I have seen em flip over and crawl, and of course I have seen em just sprint off but not get very far. The shock wave that the 375 Ruger delivered was veddy impressive. No big bones hit, all lung and heart, and the brain never registered the flee thought at all, it was too cool. I cant wait to load some 300 grain Nosler Partitions/Accubonds up for this thing. This is the largest caliber rifle I have ever owned and I have always heard guys say that the 375 is the starting point for "stopping" calibers for dangerous game, all I can say is .......I'm impressed! Now if only I can draw a Kodiak brown bear tag to test this thing out on!...grin
