so your going to hunt bear in maine and are wondering what the best bear round is. Since its maine you will be hunting black bear. I hunt a lot of black bear and have used a 30-06, 7mm rem mag, 12 gauge shotgun slug, 00 buck shot, and a compound bow and they have all done the job.

But my favorite caliber for bear has to be my ruger m77 in 7mm rem mag.
