Had the same thing happen with a 300wm and a 215 Berger. Thru the shoulders, it got into a thick swamp immediately, right before dark, and found it the next morning, still barely alive.The only bear I’ve ever killed was through both shoulders with a 270 130 accubond at 260 yards, it broke both shoulders but was still alive the next morning. Definitely going to avoid that far forward from here on out.
Arrow thru the middle that looked like a gut shot, bear ran flat out and then collapsed only 80-100 yards away. Dead in maybe 6 seconds total...
Same results on another with 215 thru the middle( I actually learned something for once) except it didn't run at all, it just rolled downhill a bit. Stone dead.
