Ok to take this a step further, what about a buck who has a broken main beam before the brow so there is a small but thick spike and a fully branched other side? I think this counts as a spike right?
It is called an unbranched antlered deer. They removed the term spike from their terminology. It can be a 2 pt on one side and 1 point on other and be legal as an unbranched antlered buck. I guess if it broke off on one side but was still at least 1 inch or more remaining as a single point, it is legal as an unbranched. Kid shot one like that at our place last year.
I never thought about if one side was completely broken off. That would not be legal according to the regs. I wouldn't shoot one anyway.
