He has a 150 frame and if he is a 5 x 5 that's where you start. I have 155 set of sheds on my work bench I am staring at and that is with an average 18 inch frame. That buck will score higher than these sheds. More main beam length on these is 21 inches, those look to be more like 23 or 24 - great wrap. These G2 and G3's are 9 inches. I also have a 165 inch set that is similar to both the kicker is the measurements between points or the girth. You have to figure if you just average 1/2 extra on 8 measurements is 3 to 4 inches. I think your buck will gross 163 and maybe net in the high, high 150's.
