I have shot a lot of small game over the years with Cedar shafts . Shot and hit MANY a large Oak , Hickory ,Maple, Ash etc tree, with a miss. Don't ever remember breaking a shaft . Rocks are a different story . I HAVE broken a number of Cedar shafts on rocks with ground shots . POPLAR is a very good choice either to order them or make your own from Poplar dowels . I buy 3/8 dowels and Then taper the rear 14 inches to 11/32. And taper the forward end to 23/64s ( only about 4 inches ) I use numerous types of small game heads , Steel blunts, Judos, 357Mag cases ( weighted), HTMs, and some other commercial types . I try to limit my ground shots to HTMs or Judos Less likely to break a shaft .
