I had my first bear made into a rug, shot broadside at 20ish yards with a 30-06, remy 180g corlock. The bear only went about ten yards and fell over, the exit hole in the hide was almost imposible to find from the outside as was the intry wound. The thick hair hid the holes completly and there was almost no blood on the ground between where he was hit and where he died. I don'w know it the taxidermist fixed the holes or not but I can't find them on the rug and I have looked. My second bear was shot at 5 or 6 feet with a 45-70, 405 grain hard cast lead buf bore ammo, bullet hit under the chin and exited just above the tail. Ripped a good hole but the taxidermist totally fixed it, can't tell it was ever there. The only reason I took a frontal shot is cause the hounds had the bear bayed up in a hole in some rim rocks and the dogs were dead set on getting him out.
I have seen a few black bears killed and in my experince they don't leave much of a blood trail.
So your state has decided that it's safe to use a rifle for bear but not deer? Lame.
