Saxon Pope in his book shot an Ishi arrow that he said shot the best of all the arrows tested for distance. He said it weighed right around an ounce. The best yardage he got from a bunch of different aboriginal bows that he shot was 287 yds. out of an 80 lb. bow. Other shorter plains sinew backed bows shot the arrow between 90, and 150 yds. Ishi made a 45lb. sinew backed yew bow that at 45 lbs. shot that arrow at 202 yds. Not as good as you flight guys are shooting arrows now, but impressive for his time comparatively. A one ounce arrow is 437.5 grains. Made from bamboo it would have been tapered at the nock end. Fun book to read.
