In ks the regs say visible polished antler. That can be interpreted different ways. I would think that if it is reasonable that the antlers were not visible at the time the shot was taken you would be within the law to use your antlerless tag-we had this discussion one time w/ a game warden & convienced him that my buddy who was a first time deer hunter had not broken the law when he shot a 3" spike buck @ 100yds. Seemed reasonable to me at the time.
