So...if you shoot a deer that does not have a legal spread, you can just break off one side to make it legal? After all, the GW can't prove it was not broken when you shot it.
That is the ethical conundrum I would wrestle with. I would not want anyone to think I broke one side to make it legal, so I would pass.
No, in an AR county a legal buck must have at least one unbranched antler, or, both antlers branched and an inside spread of 13" or greater.
Unbranched antler = An antler having no more than one antler point.
Antler point = a projection that extends at least one inch from the edge of a main beam or another tine, the tip of a main beam is also a point.
If a buck has a single unbranched antler = legal.
An unbranched antler on one side and any number of points on the other side = legal.
There is no minimum width requirement for a buck with at least one unbranched antler.
No reason to break off an antler if one side is unbranched.
A buck with a single branched antler is not legal, because it does not meet any of the AR requirements for a legal buck and there is no way to measure inside spread with only one antler.
