Bowhunting: How to Find Your Bow's Maximum Effective Range

Bowhunting: How to Find Your Bow's Maximum Effective Range - 4


▶ All bowhunters have an effective range, or more appropriately put, a maximum shooting distance that lies within their comfort zone. For some, it’s 30 yards; for others, 60 yards. Compound bows have an effective range too—the distance at which the bow is capable of lethally delivering an arrow.

A bow’s effective range is determined by two factors: arrow speed and the kinetic energy at impact. The laws of physics dictate that as an arrow travels downrange, its trajectory decays as gravity and aerodynamic drag affect its flight. Every compound delivers arrows at a defined speed at certain target distances.

So if you can determine how a bow performs at different distances, you can make an educated decision on how far you can effectively shoot at game. To define your bow’s effective range, we’ll use the sight pins. When we’re done, you’ll know the specific range of distances at which each pin is capable of delivering a lethal shot. A Simple Calculation

▶ The kill zone on a whitetail standing broadside is roughly an 8-inch circle. An arrow placed anywhere in that zone will result in a deadly shot. An arrow delivered outside that strike zone will be non-lethal.

Mark the 8-inch kill zone on your target. Shoot at the kill zone from 20 yards with your 20-yard pin. Your first arrow should hit dead-center in the 8-inch zone, since your pin is sighted in for 20 yards. Now move forward 1 yard and shoot again. Keep moving 1 yard closer to the target with each shot. At a certain distance, you’ll notice your arrow hits above the kill zone. At this distance, you have exceeded your 20-yard pin’s ability to deliver a lethal arrow. Write down that distance.

Now repeat, starting at 20 yards and moving back 1 yard with each successive shot. At some point your arrow will drop out of the kill zone. Write this distance down. Now you have a range of yardages at which your 20-yard pin is capable of delivering an arrow. Repeat this process for each pin.

I agree with the other posts in that this title is misleading. Yes Kinetic energy is important to kill game but this article has to do with the relationship of pin setting, distance and knowing where your arrow will hit.

That too, is very important!

Couple years ago I missed a beautiful buck that came TOO close. About 8 yards and because it was so close my arrow hit too high for a quick kill and too low for the spine. It got away. After that I practiced just what is described in this aricle. I haven't had a buck get that close again but if it does I won't make the same mistake again.

Eastons website has a guide to the suggested K.E. for various sized game
GAME GUIDE
KINETIC ENERGY
HUNTING USAGE
25 ft. lbs.Small Game
25-41 ft. lbs.Medium Game (Deer, Antelope)
42-65 ft. lbs.Large Game (Elk, Black Bear, Boar)
65 ft. lbs.Big Game (Cape Buffalo, Grizzly)

Stickemarchery has the calculators to do the math

sorry OL wouldnt let me post links, hope this helps

This is seems more of a guide to finding where to hold pins for various ranges, not for effective range. you mentioned K.E., just because you can hit at 60 yards doesn't mean you arrows still has enough K.E. you penetrate and make a clean kill. still a good tip though.

The title of this article of somewhat confusing, it should read "How to find your BOW'S maximum effective range", since that's what the article is actually about. Other than that, this seems like a good tip.
