Where to Shoot an Elk with a Bow: Shot Placement for Clean Kills

Elk are the largest big game animal most North American bowhunters will ever pursue. A mature bull stands five feet at the shoulder and weighs 600–900 lbs — yet his vital zone is smaller, proportionally, than a whitetail deer's. First-time elk hunters often misjudge where to aim because the animal's sheer size creates an illusion of a large target. Understanding elk shot placement before you ever set foot in the mountains is one of the most important things you can do to ensure a clean, ethical kill.

This guide covers elk vital zone anatomy, every major shot angle, what the table stakes are for each, and what you should do the moment the arrow flies.

Elk Vital Zone Anatomy

The primary kill zone on an elk is the cardiopulmonary cavity — the heart and both lungs. Combined, these organs fill an oval roughly 18 inches wide by 14 inches tall in a mature bull. That sounds large until you realize the bull's body is four feet deep from spine to brisket, and the lungs are tucked higher and further forward than most hunters expect.

Heart

The heart sits at the very bottom of the chest cavity, just above and behind the elbow. On a broadside elk, the heart is roughly one-third of the way up from the bottom of the chest. An arrow that strikes the heart produces a very fast kill — usually 50–100 yards of travel — but the heart is a small, low target. Threading an arrow between the legs and into the heart requires a near-perfect broadside angle. Most hunters aim slightly higher, targeting the lung cluster, and accept a heart shot as a bonus if the arrow drops a bit low.

Lungs

The lungs are the primary target for bowhunters. Both lungs together span the widest, most forgiving target in the chest. An arrow through both lungs collapses them simultaneously, causing rapid blood loss and usually a death within 100–200 yards. The lungs start roughly one-third up the body and extend to about two-thirds up — but they are positioned forward, behind the shoulder blade. The aiming point on a broadside elk is directly behind the crease of the front leg, one-third to halfway up the body. Do not aim at the center of the body mass — you will hit liver or gut.

Liver

The liver lies immediately behind the lungs, below the spine. A liver-shot elk will die, but it may take 6–12 hours and can travel long distances. Liver hits happen when hunters aim too far back. The liver shot is not a shot to aim for — it's a consequence of aiming behind the ideal window. If you suspect a liver hit, back out immediately and wait a minimum of 8 hours before tracking.

The High Shoulder: Skip It on Elk with a Bow

Some hunters advocate for the high shoulder shot to anchor deer in their tracks by striking the spine or shoulder blade. On elk, this approach is high-risk with a bow. The shoulder blade on a bull elk is thick, dense bone — 3/4 inch or more. Even heavy arrows from fast bows frequently fail to achieve full penetration on a high shoulder shot, resulting in a wounded elk that travels miles. Save the high shoulder for rifle hunters. With a bow, aim for the soft tissue of the lung window.

Shot Placement by Angle

The angle at which the elk is standing determines where you aim and whether you should shoot at all. Here is how to read each scenario.

Shot Angle	Aim Point	Pros	Cons / Notes
Broadside	Behind front leg crease, one-third up from bottom of chest	Largest target, both lungs accessible, best blood trail	Wait for the near-side leg to step forward before releasing
Quartering-away	Aim to exit through the off-side shoulder — drive the arrow through	Excellent penetration path, both lungs in the arrow's path	Aim further back than you think; visualize the exit point first
Quartering-to	Only take if angle is slight; aim for the near-side armpit/front leg	Can work on shallow angles	Near-side shoulder blocks access at steeper angles — wait for better
Straight-on (head-on)	Do not shoot	None	No ethical bow shot; shoulder blades block both lungs
Straight away	Do not shoot	None	No ethical bow shot; no path to vitals

Broadside — The Ideal Shot

A perfectly broadside elk is every bowhunter's goal. The lung window is fully exposed, there is no bone blocking the arrow's path, and both lungs are directly in line. Wait for the near-side front leg to step forward — this opens the armpit and removes the tricep muscle from the path. Aim directly behind the front leg, one-third to halfway up the body. If you split the difference between the leg crease and the middle of the body vertically, you'll be on the lungs.

Common mistake: aiming at the center of the elk's body, which places the arrow in the liver. The lungs are in the front half of the body. When in doubt, aim a little forward, not back.

Quartering-Away — The Second Best Shot

A quartering-away elk presents an excellent shot opportunity, often better than broadside because it puts both lungs in the arrow's path across a longer distance, maximizing damage. The key is to visualize where you want the arrow to exit — ideally through the off-side shoulder or lung — and then aim accordingly on the near side, further back than it feels natural. On a 45-degree quartering-away angle, you should be aiming at the back edge of the ribcage or even the flank. The arrow will angle forward through the body cavity and exit through the opposite lung.

The mistake hunters make on quartering-away shots is aiming too far forward, hitting only one lung or missing the chest cavity entirely into the guts. Commit to the exit point first, then find the entry point on the near side.

Quartering-To — Proceed with Caution

A quartering-to elk can be shot ethically, but only on a slight angle. On a shallow quartering-to presentation — say 20–30 degrees off broadside — the near-side shoulder is still mostly clear and you can thread an arrow through the armpit into the chest cavity. On steeper angles, the near-side shoulder blade fully blocks both lungs. If you can't draw a clear mental line from your arrow's entry point to the far-side lung, don't shoot. Wait. Elk frequently shift position within seconds.

Head-On and Straight Away — Never

There is no ethical bow shot on an elk facing directly toward you or directly away from you. Head-on, both shoulder blades form a wall in front of the chest. Straight away, the pelvis and spine block the body cavity. Pass on these angles every time.

Why Arrow Choice Matters on Elk

Elk are not just big — they're dense. A bull's hide is thick, his ribs are stout, and the muscle mass around the shoulder is substantial. Arrow selection has a direct impact on penetration and the margin for error on off-angle shots.

Use a Heavy Arrow

A minimum of 450 grains total arrow weight is the standard starting point for elk. Many experienced elk hunters shoot 500–600 grain setups. A heavier arrow carries more momentum — it keeps moving through resistance when a lighter speed arrow would deflect or stop short. This matters on quartering shots where the arrow must travel through multiple muscle groups and possibly clip a rib.

Momentum (mass × velocity) is the number that governs penetration on large game, not kinetic energy alone. Two arrows with the same kinetic energy but different weights will not penetrate equally — the heavier, slower arrow will almost always penetrate better on large game.

Use Fixed-Blade Broadheads

For elk, fixed-blade broadheads are the near-universal recommendation among serious bowhunters. They maintain their edge and cutting diameter through bone and dense tissue where mechanical broadheads can fail to deploy or break. A two-blade or three-blade fixed broadhead in the 100–125 grain range paired with a heavy arrow is the standard elk setup for a reason. See our full comparison of fixed-blade vs. mechanical broadheads for more detail on when each makes sense.

Higher FOC Helps

Front of center balance — the percentage of your arrow's total weight that is forward of center — affects both flight stability and penetration. Higher FOC (15–20%) promotes nose-forward penetration on tough game. A heavier broadhead and lighter fletching push FOC forward. This is one of the reasons many elk hunters run 100–125 grain broadheads on already-heavy arrows.

After the Shot: What to Do

The moment the arrow flies, your job shifts from hunter to tracker. How you handle the next few hours determines whether you recover your elk.

Watch the Animal

Keep your eyes on the elk after the shot for as long as possible. Watch which direction it runs, note any landmarks it passes (a distinctive tree, a rocky outcrop, a saddle), and observe its behavior. An elk that runs hard with its head down and stops quickly is a good sign — likely a double lung hit. An elk that hunches up, kicks out, or walks off slowly may be gut or liver shot. An elk that acts unaffected and walks away may be a marginal hit or a miss.

Listen

After the elk moves out of sight, sit still and listen. A lung-shot elk in timber often crashes within 100–200 yards — you may hear it fall. A gut-shot elk will travel much further and you won't hear it stop. Silence after a few minutes of crashing timber is generally good news.

Wait Before Tracking

Patience after the shot is one of the hardest disciplines in elk hunting. The instinct is to go immediately, but pressuring a wounded elk can push it miles further than it would have traveled on its own.

• Double lung hit: Wait 30–60 minutes before tracking. These elk rarely go far.
• Single lung or heart hit: Wait 1–2 hours.
• Liver hit: Wait a minimum of 8 hours. Back completely out of the area.
• Gut hit: Wait 8–12 hours. The elk will bed down and stiffen. Pressure will push it out of its bed and it may run indefinitely.
• Unsure: Back out and wait at least 4 hours, then reassess based on the blood trail.

Mark and Start the Blood Trail

Mark your exact position at the shot and mark where you last saw the elk. Find the arrow if possible — the color, smell, and amount of blood or tissue on the arrow tells you a great deal about what you hit. Bright red frothy blood indicates lung. Dark red blood indicates liver. Green or brown material with foul odor indicates gut. Start the blood trail from the point of impact, moving slowly and marking each blood spot as you go.
