Hunting Rock Chucks & Marmots

Hunting Rock Chucks & Marmots
Marmots live in rugged country and are very wary–they’ll keep your hunting skills sharp.

The best squirrel hunting you’ll find in much of the West is pursuing yellow-bellied marmots. We’ve got limited opportunities to hunt fox squirrels and red squirrels just aren’t very large. Marmots are among the largest critters in the squirrel family and are found across the country, especially in the northern latitudes and high elevations. They make their homes in rock piles and eat grass.

Yup, I’m talking about rock chucks.


In the East, you’ll know them as woodchucks or groundhogs, like Puxatony Phil of Groundhog Day. Suburban recreationists consider them an adorable high altitude wildlife sighting. But around the West, farmers consider them a crop-eating pest, while shooters consider them live-target practice.

Calling them rock chucks makes it easy to dismiss them as vermin, which makes it easy to shoot them as pests. But, if you’ll give them a chance, you’ll find that they are good table fare and a terrific way to keep your hunting skills sharp.

When to Hunt

You’ll find marmots active during daylight hours, though on hot days they’ll retreat to their burrows at midday. They come out just before sunrise and are gone at sundown. But don’t feel like you need to get up early. You can take a long lunch or leave work an hour early and have a good hunt.


Marmots like to live in rocky cliffs and rock piles near grassy fields. They hibernate as much as nine months of the year, depending on elevation and weather. They may emerge as early as February, or as late as June. In southwest Idaho, we start seeing them mid-March near farms and feedlots.

Hunting Rock Chucks & Marmots
A nest of grass and straw like this will let you know Marmots are in the area, but they often build completely underground, too.

They eat like maniacs for a few months before going back into their dens to sleep through the hottest summer months and then through the winter.

Marmots are predictable. They live in groups of six to twenty and generally hang out in the same area. There’s usually a lookout who perches on a rock in the full sun and keeps an eye out while everyone else is feeding. You’ll often see them sprawled on a rock in the sun.

Look for scat like this on top of rocks. It’s often piled up quite a bit in spots where Marmots layout in the sun. Gun for scale.

They have sharp vision, and if you’re within 300 yards they have probably noticed you. They’ll disappear from their perch but get another look at you from another spot a few feet away. Look for their little triangle-shaped heads sticking up from the outline of another rock.

Their sharp vision is why folks love to use them as long range targets.

Long Range Shooting

Their coloring blends well with rocks, but look for their bodies splayed out on a large prominent boulder. You’ll need binoculars and spotting scopes for extra range. Heat shimmer off the rocks can make spotting difficult, so the early hours are a little easier for long range shooting.

Marmots range from the size of a chihuahua to the size of a terrier. Remember to pick a spot on the critter to make a precise shot. They are remarkably resilient, so proper shot placement is key. Go for the lungs or head with a .223 to ensure a quick kill. Use .17 HMR to make headshots for a real challenge.

Of course, more powerful rounds will send them flying or exploding like pumpkins, but doesn’t leave much left to eat. It takes a lot of skill to shoot small rock chucks from a distance with a large caliber rifle, but hunting marmots with a .22 will hone your hunting skills in many ways.

Hunting Marmots

Marmots like open country and utilize their lookouts well. In busy areas, they’ll disappear when they see cars drive by, and they’ll run away if you get within 300 yards. When you hear their high sharp chirp you know you’ve been spotted and they’re running for cover.

Still, if you use good hunting techniques, you can get within 50 yards and kill them with a .22 long rifle. Since you’ll find lots of animals in one place and get many opportunities to kill them, they are a terrific hunt for first-time hunters and youth.

CZ’s new 457 rimfire series are bolt action guns and are excellent for hunting marmots. This is the 457 Scout.


A .22 rifle is a terrific tool for hunting marmots. Ruger’s ubiquitous 10/22 is a good choice for fast followup shots, but making killer shots with a bolt-action gun, like CZ’s new 457 Rimfire Scout is very satisfying, too. Open sights are fine since most of your shots will be within fifty yards, but I prefer a light scope.

I just got Winchester’s new Wildcat .22 and fitted it with a Vanguard 1-4x scope. A 1x optic makes it easier to make shots on the move while zooming to 4x makes it easier to place killer shots from afar. Though it’s fairly short, the Wildcat’s heavy barrel is very accurate and consistent. A sling will make it easier to use binos as you walk.

Hunting Rock Chucks & Marmots
A .22 rifle, like Winchester’s new Wildcat semi-auto, is the perfect tool for hunting marmots.

You’ll want 8x or 10x binoculars. Keep them around your neck and plan to use them continuously. Use a range finder to help you stalk within range. It’ll also hone your estimation skills for big game seasons.


Marmots are often hunted and they associate vehicles with danger. Drive into your spot at normal speed and hide your vehicle behind a hill.

Be sneaky as you walk from behind mounds and rocks. Use your binoculars before exposing your whole body from behind cover. Don’t walk as you spot because they’ll see you. Look around carefully, then proceed.

Be Ready

You’ll spot marmots from a few hundred yards and you can plan a stalk, but also be ready for a jump shot. Unlike cottontails, they won’t stop and look back once they flush. You’ll get opportunities for a shot on the run, but remember to take aim and go for the lungs.


Once you spot a marmot, use cover to stalk within range. Wear camo — like big game, they don’t see red colors well, but they see forms and movement very well. Camouflage will help break up your human shape.

Hunting Rock Chucks & Marmots
Marmots aren’t the only critters in the rocks. Make sure you don’t kneel down in an ant pile and watch for snakes before you put your hands down on the ground.

Use your rangefinder. If the critter is 156 yards away, you can range other rocks to find one you can use as cover to get a shot. A rock that is 120 yards from you will get you 36 yards away for a shot. Make sure that you can stay behind other rocks all the way there. You’ll find yourself on your knees occasionally. Watch out for ant hills.

Be wary of other marmots nearby. While you’re creeping up on one of them, another you didn’t see will spot you and sound the alarm.


Once you’re in range, sneak your barrel out from behind cover. Take careful aim. Pick a specific tuft of fur, and go for the head or lungs. Aim for the eye, or just behind or in front of the armpit.

Treat it like a grizzly bear: if it’s still moving, shoot again. I have often made a good shot and then walked over to find a blood trail disappearing into a burrow. Marmots are resilient so take another shot whenever possible.

Hunting Rock Chucks & Marmots
Use your binoculars to find marmots hanging out on top of rocks or foraging in groups at the edge of fields.

I’ve had good luck with hollowpoint bullets, like Winchester’s recently re-released Wildcat copper bullets. I think the higher velocity CCI’s would be a great idea, too. Sub-sonic bullets are not a good choice.

Once you shoot, the other marmots nearby will run into their burrows. But, if you sit still for another 5-10 minutes, they will probably pop their heads back out and give you another opportunity for a kill.

Meat Care

Marmot meat is red and delicious. It eats the same alfalfa and clover as the cows in the field at the bottom of the cliff. Get the carcass gutted and the meat cooling quickly. The hides are incredibly tough, so bring a sharp knife and don’t be surprised if you need to sharpen it while working. I’m having a hide tanned right now, and I’ll let you know how it turns out.

Be Safe. Small game mammals may have ticks or fleas that carry bubonic plague, Rocky Mountain spotted fever or tularemia. Wear gloves when cleaning and cook the meat thoroughly. Pay attention to the liver, if it is discolored or mushy or swollen, I’d discard the meat.

Hunting Rock Chucks & Marmots
You can render the fat and make a useful cooking oil. It’ll harden in the fridge and then you scoop it out like coconut oil.

Marmots are just large squirrels with dark meat. You’ll find early season animals packed full of grass, while later in the season they are packed full of fat. Try your favorite rabbit or squirrel recipe, but be sure to marinate for a long time because the meat can be tough. The texture is a lot like a pork roast, and you can even render the fat from late-season animals. Try this tasty Spice Braised Squirrel recipe to prepare meat for pulled sandwiches or enchiladas.

Have Fun, Hunt Year-round

Small game hunting offers a year-round opportunity to keep your hunting skills sharp, spend time outdoors, and introduce new hunters to the traditions and fun of hunting. When rabbit and bird seasons have closed for the summer, you can still hunt marmots. Many folks shoot rock chucks from afar and they think I’m joking when I say they’re a fun hunt and tasty dinner. But if you get out there and try it, you’ll find marmots are a wary prey and make a delicious pot roast.

So, dust off that .22 and go hunt one of the biggest squirrels in the country.

    I would never suggest using a 22 for hunting rock chucks, seen way too many gut shot to suffer before death. don’t get me wrong I like hunting them and I like helping farmers but more horsepower in your weapon makes for instant kills. and even upper body and head shots with a 22 doesn’t always guarantee and dead rock chuck

    I have killed thousands of chucks over the past 35+ years. One memerable day I was shooting by my sell, much more fun with a good buddy, but this day I remember shooting 100 chucks. Twenty were shot with a 204 Ruger, the remaining 80 were shot with a 17 WSM. The ammo I used for the 204 was some reloads with 40 gr V max, 20 gr V max with the 17 WSM. Ranges with the rimfire were mostly 50-100 yards, but I did get several around 125-150. I can’t recollect my exact shot count, but I didn’t use 2 boxes of WSM ammo. About 5 years or so ago I started using a 17 Rem. Fireball. This has become one of my favorites. Super mild recoil, so you can see your hits and misses. I use a 20 gr. V max around 3600fps or a bit more. My first shot with this rifle that I shot at a chuck, it was 410 yard away, sitting on top of a rock shortly after sunrise. I organized my rifle on the bipod and sandbag, took careful aim, and decided to hold just above the chucks neck, and kaboom, down rolled the chuck off the rock. You don’t get the violent airtime as with bigger calibers, but you get to see where you hit. You can make most any caliber work, but the buigger the bullet, generally the more the expense. When you shoot 4-800 critters in a couple weeks, it easier on the wallet with the smaller projectiles. Have fun, be careful and shoot straight.

    I’m just getting into southern Idaho chuck hunting. Ive heard the standard “theyre everywhere” but need specific locales, towns, etc to start. Any suggested public lands statewide? Thanks.

    I know this is a shooters thread, but I’d like to know if anyone hear uses small terriers to take marmots?

    I’ve hunted eastern “ground hogs” and western “rock chucks” all my life and like the man said, they are wary but much more so are the chucks of the west, it is a great challenge to take a chuck at long range and I’ve hunted them with about everything from a 22 pistol to a 50 caliber Sharps and it is great fun and a relaxing way to spend time with some buddies on a camping trip.

    I live in CA. can I use Sierra >25 gr. hollowpoint boat tails for hunting? Thanks. RG

      25 grains would be light for rock chucks. I use 40 grains and they often walk away. I’d try a heavier bullet, or smaller game. 25 grains might be appropriate for tree squirrels.
