Ok so you picked a bullet that opens decently wide, with a relatively low SD, and shot a large animal in the neck, which is some of the densest tissue in the body. Right.
Yes, and as I said, at 282 yards I fully anticipated the 150g/.308” AB would exit on a neck shot. Impact velocity and energy calculate out to about 2542fps and 2152fpe. That is considerably more than a .30-30/150g can muster at the muzzle.
A bullet’s starting SD is much overrated in my book – once bullets expand a difference in mass of 10-15g makes remarkably little difference. For example, here are the SD values for four bullets expanded to 0.5”: .080 = 140g .086 = 150g .091 = 160g .094 = 165g
I’ve driven 7mm/140g NF ham-to–sternum on buck mulie. That bullet passed through a grass-filled gut, which isn’t exactly fluff. It took me 20 years of shooting elk to recover a 7mm/160g GS and that one had destroyed both shoulder joints of a 5x5 bull before coming to rest peeking out of the bone on the far side. I have recovered a couple of .308”/165g NF from elk but they also encountered heavy bone before coming to a stop under the hide on the off side. As to MRX/TTSX, I have yet to recover one in any weight and my hunting buddy has never recovered a TB. My hunting buddy has also taken both a 5x5 bull and a cow with neck shots using a 160g GS. The one on the bull took out a section of spine and both exited.
I guess I was just expecting too much out of the 150g AB.
