BB, most of my guys show up with just about everything. Most common would be the 308, the 30-06, variations of the new mag 30 cals. the odd 45-70 and the occasional 12 ga with slugs. By far, the most damaging to a bear was the slug gun but any 30 cal worked just fine. The bottom line was always a good solid broadside hit that resulted in few bears travelling very far. The bears that travelled the farthest and are most often lost are those taken by archery hunters but weird as it is, many bears taken by archery don't travel as far as those hit by a rifle. You figger that one out[:-]
