View Full Version : Ibo Speed grnark 01-16-2008, 08:12 PM Everything I read about IBO speed says the standard is based on a 70# draw weight, 30 inch draw length, and a 350 grain arrow. Does 350 grains refer to the total weight of arrow and field point together or is the 350 grains just the arrow weight and the IBO standard assumes some weight for the field point?? bullfiddle 01-16-2008, 08:18 PM Everything I read about IBO speed says the standard is based on a 70# draw weight, 30 inch draw length, and a 350 grain arrow.
