I called this buck a 190” buck and I base my opinion on the 168” buck I have on the wall that I look at daily. This buck has longer tines, forks and has eye guards that my buck lacks. Both bucks in my opinion are 28” wide, mine for sure and this one I believe is 28” wide.
Mass gives you little for score. Deep forks and 5 long tines is where true scores come from. Oh ya and those extra tines on nontypicals that make high scores easy.
