What weight is considered a heavy arrow

<< < (5/5)

Don W:
I am not close to caught up on the reading, but the links are appreciated and I'll definitely be going through them all. It may not be until winter sets in, and maybe even longer, it all looks pretty in-depth.

BowEd:
Correct Tommy D about FOC for penetration.
Carbide arrows are easy to get balanced FOC 6" from the tip.With wooden full length tapered dogwoods maybe 9 to 10 inches balance from the tip.Which puts them in the high teens maybe low 20's percentage wise FOC.Flying clean and true quickly from the bow.A real bone busting shaft IMO.

Here is a summary by Ashby (with real world numbers) of the relationship between mass and velocity - for one of his bows.

Also, some examples of how when you use “momentum” as the measure of an arrow’s lethality (over Kinetic energy - as is the norm in many circles), you can better understand how a bow and arrow can be just as lethal as a firearm.
