Bell, I can tell you from my years of working on wild free range PA deer, you are right about the 5x5 having shorter g2s, for the most part. Obviously it's not the case every time, but the majority of the time I would have to say that a 4x4 has longer g2s than g3s while a 5x5 has shorter 2s than 3s. That is my observation on wild PA deer two years old or older. I do see yearling 4x4s that may have equal or shorter g2s than 3s, but I think that's just a product of being young, we have enough deer in this state, if only people could stop shooting beautiful 4x4 yearlings, give them a pass and shoot a doe instead, we would see some great two year olds. But that's a whole different topic there, lol. Say that on a hunting message board and your heads on the chopping block, too many guys still complaining spikes and 4 pointers aren't legal in our state, lol.
