I guess it depends on the terrain they're hunted in, which will dictate the usual range. I've never hunted black bear in Maine, but my guess would be that hunting will take place in timber. Where I've hunted them (Northern Idaho) a bear at 50 yards is one that you'll never see. The only rifle I've ever hunted black bear with is a .400/.360 Nitro Express double rifle. With either the old 300 grain Barnes Original Spitzer (the old Barnes copper jacketed lead core bullet) or the Hawk 300 grain .030 jacket round nose at 2000 fps, black bears don't run before they die, they drop to the shot and stay down. I've always gotten an exit. Assuming you'll be hunting in timber, a 300 grain Hawk at 2000 to 2100 fps will be all you'll need.
