My .35 Whelen has the longer barrel, and it shoots nice. I load Nosler 250gr partitions, and I limit my shots to no more than 250 yards. My Dad used it to shoot a Moose a few years back, one shot at 40 yards. I would not be afraid to go after Grizzly with it. To be honest I don't carry it often, because I am always carrying my 30-06 Handi. Comes from having too many I guess.
