people hunted bears long before you and I were here to make the decision what is adequate.What was once adequate might not be to some folks today.Fred Bear killed all the bears with a recurve,maybe not the proper weapon but it was doable.The eskimos they all have 375's naw.I am sold on the 308 have been since I saw em shoot at Camp Perry in the 60's.New stuff fine,old stuff fine with me.
Pope and Young did it all with self made long bows
