I have 2 bolt rifles, shot aaalot with either, never let me down (1st Gen T3 Hunter + M.96 Commercial Husqvarna with a peep sight. They are my favs, for decades...
These 9.3 semis are nice - beauts, I would use for hunting Moose + never for Bear Defense: too many extra things to go wrong ... keep it simple - bolt 9.3 or pump 12 G. Coming from a Bear Photographer <------- blank goes up 1st, Rubber next, then all 12G slugs for bear protection. I have a good buddy who takes aaalot of Polar Bear pics, way more outdoors + animal pics than I - same load out with a 12 G. Pump 12" brl full stock.
But they sure look nice and shoot well ✔
