All these probably been mentioned in prior posts but #3,4,5, are probably the most sure fire way to tell the differance.

1) A lone deer is often a displaced BB.

2) If 3-4-5 deer walk out to feeding area,many times 1st one out will be the BB(their cocky and stupid).

3) The BB head will always be flatter than Doe. A biggy

4) Doe will have a dome shape noggin. A Biggy

5) Doe head is long and slender compared to short stubby lookin BB head. Another Biggy

Having said all that,everybody is gonna make a mistake once in a great while. I have thru the years.

I hunt a lease farm. We have all finally agreed we are going to make serious attempts at not shooting any BB's or spikes. We have couple guys that shoot 1st and ck head gear later. I keep tellin these clowns that a BB(or spike) is next yrs 6-8 point and the following yr 10-12. I think its finally sunk in.
