RE: Advice on Browning Bar - Please
Goodguy, I own a BAR in .270 and I have never had it jam. It is also very accurate with a Nikon Monarch scope and a BOSS on it. I love the fact that it is light on recoil and I get a quick follow-up shot if needed. On moose this might be something to consider as I understand they can take a shot or two or three before giving up the ghost. Good luck whichever you decide.
P.S. I am a lefty also, and I got turned on to the BAR because of the relative scarcity of southpaw bolt actions. My cousin who has been a hunter for 40 years uses one for the same reason.
