I have a 673. It's no heavier then the average sporter. I much prefer it's 22 inch barrel length to the 600's 18.5 inch barrel. Much more muzzle blast on one that short. 20 or 22 is about optimum in a .350 in my opinion. I can live without the raised rib but given it's positive points it works for me. It really thumps black bears.
