So much emphasis lately had been directed towards arrow speed. It seems to me that most archers are searching out the absolute fastest bows on the market and want bows that are even faster…and manufacturers are developing
bows to fill the demand.
But how fast of a bow does one really need? And what are you giving up in a bow that shoots upwards of 330 feet per second (fps) or more?
Brace height (distance from back of riser to string) is the primary determining factor in bow speed. In general, the shorter the brace height, the faster the bow is. But, the faster the bow, the less forgiving it is.
Because the arrow leaves the bow at such a high rate of speed on bows with short brace heights, any flaw in your form or any twitch or mishap during
your release is going to be severely magnified when it comes to your accuracy. You will still have accuracy problems with long brace height bows too but the errors will not be as severe.
And how much arrow speed do you really need anyway? Let’s compare arrows traveling at 330 fps and those traveling at 280 fps. We’ll use a middle of
the road distance...30 yards (or 90 feet).
It would take the 330 fps arrow about .273 seconds to travel 90 feet (just a bit more than ¼ of a second).
It would take the 280 fps arrow about .321 seconds to travel 90 feet (just under 1/3 of a second). That’s a difference of .048 seconds (less than 1/20 of a second)!
Now, every deer reacts at different speeds based on different circumstances. But for arguments sake, we’ll say that a deer can react to the sound of your bow in about .100 seconds (1/10 of a second). The average human reacts in about .23 seconds (a little less than ¼ of a second).
All of these numbers mean just one thing…the difference in arrow speed between the 330 fps arrow and my 280 fps arrow is negligible when it comes
to the deer reacting to the sound of the bow at 30 yards. In other words, I don’t have to aim any differently that the archer using the 330 fps bow. At closer distances, the differences become even less.
To be fair though, you do gain one advantage when shooting a faster bow….since the trajectory is somewhat flatter on faster bows, you are able
to shoot through slightly smaller openings.
So what’s it gonna be? Are you going to go for all that speed and hope that you don’t flinch during your release and not gain all that much when it
comes to overcoming the deer jumping the string? Or, are you going to shoot a bow with moderate speed and gain a whole bunch of forgiveness?
As for me and mine…I’ll take bow forgiveness over arrow speed any day.
