Traditional equipment in general has limitations...that's part of the challenge of getting closer to game. The different types of equipment within traditional bowhunting can further limit the effective range. Whether its longbow, recurve, selfbow...carbon, wood, aluminum, cane etc. arrows...single bevel, double bevel, two, three, four blade, steel or stone or glass heads...the choices are almost endless. The poundage of the bow you choose is yet another potential limitation. I think its best we all learn how to hunt better, shoot better and get as close as we can. Do our best to make an accurate shot and a quick clean kill. A seventy pound bow wont cover up poor marksmanship for very long. Shoot what you can handle whether its 40# or 100#. Accuracy trumps poundage. Personally I shoot bows in the 50 to 60 pound range best. Thats my choice and I understand the limitations involved. For those oops and unforseen circumstances the best thing is to learn how to follow up and track game.
