There is a huge difference between free range and high fenced deer. Milo Hansen's deer is nothing compared to some of those freak you find on game farms...
Milo "run over the neighbor's fences" Hanson? LOL!
Yeah, that was a big deer. I think his hunting style deserved more coverage, though.
There are freaks out in the wild to, not just behind the fences. About all I would hold the fenced farmers up for, is as an example of what the potential is for larger/funkier/'better' growth potential, if all the stars happened to align and the right combination of genetics, nutrition, and luck, came together. Not counting those that are busily injecting their livestock with whatever they think will make it bigger than the competition's.
I'd be mostly interested in finding out whether the antlers on that buck in the first post were as a result of genetics, and infection during the antler growth stages, or an injury. I lucked in to a mulie buck that was a classic 4x4 except with the addition of a bookmatched pair of drop tines under the main beams, and he had been seen the year before with a similar set of antlers, so he seemed to be genetic. I also shot a very screwed up white tail with a set of antlers that would fit nicely in to a shoe box, the one looked a lot like an antelope horn, the other was a twisted runt of an antler, the supposition of a couple guys was that he had been injured at some point, as supposedly a spinal injury can play hob with antler development too.
Like I said earlier, I'd happily shoot that buck over a similar sized typical. Just for it being a bit different. But the guy that came up with the "Biggest" line, needs to get out more, and see what is actually out there.
