A gun for bear hunting
To this day, I have mostly used my dad's old bolt action Mosin Nagant from the 2nd WW but its not reliable nor efficient, and it jams a lot! I'd need a replacement, but Finland's gun policy is strict. Which is the most efficient gun I can get? Keep in mind that they don't sell them at every shop so I should get a good one and keep it for a long time.
Which caliber is good for shooting bears?
