Anytime AR comes up in a thread, you run the risk of a highjacking.

In PA, Where the 3 point AR won't work, we have 4 point AR. That's where I goofed up. I'm still wondering what percentage of 1.5 year old bucks have 3 points or less. In my area I believe it isin excess of80%, if my memory is correct. This fits in with my observations from the last 28 years of hunting. This would leave almost 20% of 1.5 year old bucks that carry 4 or more per side, i.e. your nice 1.5 year old 11 pointer.
Glad you found the BB. I know it's just consolation at this point. A good lesson nonetheless. It is interesting to see the path that a mortally wounded deer takes. Sometimes it is so simple that it embarasses the hunter, that he didn't think of it. I knew a guy that lost a deer that never even travelled out of sight of his stand. It went in a creekbed and bedded under a fallen log. We found it after it was too late.
