It is a rule that is open to judgement calls. I have never seen a "hoofer"....
The bedded buck is one that is rife with potential arguments. Depending on which side you were shooting at, if the member of your group hit right above the hoof, he hit white....is that considered a hit in 'non body color'. I overheard a conversation up there with some saying it was non body color, and was thus a zero...of course, others disagreed.
Seems to me, to make things more simplified it should be either a 0 or a 5....if it is sticking in foam, hoof, paw, claw or foot...???????
