Not the greatest picture but that's around 300". It has nice tails but the 4 is a little short as well as the 3.
This one you can hopefully see the length of the 4. Also pretty good spread and beam length. Grossed at 323 and netted 318.
Can't find the picture now of one that was 275". But look at the length of the 4's. Also how far back the beams come into the shoulder. But keep in mind it's several measurements and the difference of 20" can really only be a few inches everywhere.
My dad's 2009 bull went 273 gross. My archery bull from last week goes right around 300, maybe an inch or two below. I tried to find similar pictures of each for comparison.
My bull was a few inches wider, had much longer thirds, and quite a bit more mass that you can't as easily see in pictures. Also my bull had a bigger head and body which makes the antlers on mine look slightly smaller than they are compared to my dad's bull.
