I wouldn't shoot him. Last time I shot a swollen neck 4pt I had a heck of a time getting it ate. I think it irresponsible to knock down a nice buck and do it a disservice by letting it freezer burn in the bottom of a deep freeze not getting ate then finally tossed out with the trash. I got it ate, but I heard some complaining. Did a lot of 50/50 burgers.
I'm working on changing that, I've got a cold smoker now and I'm fixing to build a curing chamber, so now I can ferment meat and make stuff so tasty even a swollen neck stinky old buck will get ate, until then I'll shoot them early, and younger, so they'll get ate properly.
