You're talking about momentum. This always starts a heated debate on here.


The problem with just stating a lighter faster arrow compared to a heavier slower arrow is that it's all bow dependant and no numbers are presented with your statement. Meaning, how light what were the arrow used and what equipment were they shot out of?

Since traditonal bows are not very fast the traditional bows needheavy arrows to have enough momentum to push through, or into, game. That goes for people who shoot very light compound bow draw weights too.

Modern compounds can launch a light arrow at high speeds so that the arrow uses it's velocity instead of weight to push through game.

A lot of modern bows can shoot a heavier arrow at high speeds. Therefore, where do you draw the line and say that the "ligher, faster" arrow is acceptable? At some point in the equation you can have a lighter arrow that will have more momentum than a heavier arrow. I shoot a 420 gr arrow that some people would call light and others heavy. It goes along at 290 fps which is pretty fast. That meansmy 420 gr arrow has as much initial momentum as a 700 gr arrow at 174 fps.

I know a guy who shot a Kodiak Brown bear at 35 yds with a 370 gr arrow out of an Allegiance at 70 lb. To me that's enough proof that it does not matter what arrow you shoot as long as you shoot accurately.
