Dan...That's a good point. Does PA have it state-wide? I guess I haven't done much research on it.
Pennsylvania does use antler restrictions state-wide. In some areas that offer more food (more farming areas) and theoretically have better genetics (although I don't see the evidence), the restriction is 4 points to a side, so a 4x3 seven-point or a 4x2 six-point would be legal. In big-woods areas, it is 3 points to a side, so a 3x2 five-point would be legal. In the 3-point area lots of people believe many bucks lack brow tines, but I would not make that claim.
The results have been positive. While I haven't checked lately, memory recalls that we went from the harvest including about 80% yearlings (as high as 90% or even 95% in some places) to the harvest including about 50% yearlings. That's still a high number of yearlings, and it doesn't let some of those little basket 8-points and 3x2 bucks survive to age 2½. I'd like to see the state extend the 4-point rule across the state.
The difficulty with any kind of antler restrictions (whether it's point restrictions, width of main beams, or any other proposal) is in making a rule that actually works in the field for hunters across the age groups and experience levels, and is both enforceable and socially acceptable.
So, what we've done is positive, but certainly not above criticism.
I hope that answers your question, BH21.
