I'm a little surprised to see so much flak on the AB. I must say I've had nothing but good luck...
Animal #1: Muley buck 438 yds. 1st 200AB through the boilerroom. Rolled him over. He was still kicking and I was afraid he'd roll off a ledge, so I anchored him with a second shot. Both shots passed through and did so much damage I decided the 300WM was overkill on deer at that range.
Animal #2: Bull elk 638 yds. Total of 5 shots though him with 200AB out of a 300WM, 4 through the lungs/liver. I was firing fast as he did not react to the first couple shots and I was frantic he would bolt back over a ridge and complicate recovery. In truth the first shot would have been enough, all pass thru's with plenty of damage. A little less than the muley but it was 200+ yds further.
Animal #3: Whitetail buck 200 yds. NOT ME SHOOTING. Guy Texas Heart Shot him with my gun (I would have passed on that one but he went 160+ so this guy didn't), one 200AB up the tailpipe didn't stop until in the lungs. I was not there when they opened him, but the guy said he had never seen a deer so destroyed inside.
Animal #4: Whitetail buck 280 yds. DRT, plenty of damage, 200AB 300WM.
Animal #5: Antelope, 300yds. DRT, pass thru with plenty of collateral damage.
Animal #6: Muley buck, 550 yds. My buddy shot him first with a 180AB 300WM. Bullet hit in the crease but the buck hopped twice and stopped. Running would have complicated recovery so I hit him 2 seconds later with a 200AB from 300WM. Sharp quartering angle, so went through lungs and out the base of neck on far side. Anchored him. Both pass-thrus, damage enough to ruin the shoulder they hit.
I don't doubt anyone else's experience but I have not seen anything myself to make me switch.
