I need some help packing for my next bear hunt in Houlton, ME. I have a Marlin 1894 in .44mag and a surplus MKV in .303 Brit. I shoot both equally well and both are very reliable. I'm hunting from a treestand 13 feet up and about 50 yards away from my bait. My shooting lane is clear but the surrounding area is thick, heavy cover. I'm not concerned with weight as much as a one shot kil. Any ideas?
