Thanks Tim, as for the shoulder bone, I think the bullets with exposed lead cores like the game king, Hornady sp, Speer, and even the Nosler bonded would suffer a lot of early expansion, possibly even failure to penetrate to the vitals. If I were to hunt where the deer are scarce or moving and I would be forced to either take an iffy shot or go home hungry, I'd go with the GMX or Barnes all-copper. I heard rumors that Hornady was going to offer their interbond in .223, I do not think they ever did.
To those that think this was a fool's errand, then explain to me why are these bullets even made? Tooling up a bullet press is enormously expensive. The dies alone cost a bunch. Then that machine is tasked to do that "specialty" bullet instead of a more popular bullet like a 165 .308. Kudos to Nosler, Hornady, Sierra, and Barnes for their excellent bullets!
I am jealous of those that have long seasons where they can hunt many days where they can observe deer in a natural, undisturbed setting. Not the case in good ol" Wisconsin. Our 9 day season results in a mentality of take your shot or go home, often at running deer. There's been attempts to change it to something else but those that hunt with sharp sticks resist anything that would take a bite out of their 3 months.
Even attempts by primitive black powder hunters to have an early season in late October have failed, the BP season starts the day AFTER the rifle nine day season! By that time the deer have gone nocturnal and it's full on winter!
