Groundhog hunting is one of those pursuits that’s equal parts pest control and pure shooting fun. If you’ve ever sat on the edge of an alfalfa field with a good rifle and a spotting scope, waiting for a woodchuck to poke his head up, you know exactly what I mean. They’re small targets, they don’t sit still long, and the distances can stretch farther than you might expect. That’s why picking the right caliber for groundhog hunting matters.
Truth is, there isn’t just one perfect answer. The “best” caliber really depends on how far you’re shooting and what kind of terrain you’re hunting. But there are a few standouts that have proven themselves over the years.
.223 Rem: The Workhorse Caliber
Now we’re getting into what a lot of serious varmint hunters consider the sweet spot. The .223 Remington is incredibly versatile and just flat-out effective on groundhogs.
With a good rifle and quality ammo, 200- to 300-yard shots are very realistic. The cartridge shoots flat, hits hard enough for clean results, and keeps recoil light enough that you can stay in the scope and spot your shots.
It’s also one of the most common rifle cartridges in America, so finding rifles, ammo, and accessories is easy. If someone asked me to recommend one caliber for groundhog hunting, the .223 would be tough to beat. I’m not going to lie – it's my personal choice for groundhogs and other varmints.
Suppressor Suggestion: BANISH VRMT 223 TI
The BANISH VRMT 223 Ti is a great suppressor for predator and varmint hunting with popular cartridges in .224 caliber and smaller. It is made from titanium, has an industry-standard HUB mount, and a removable baffle stack for easy cleaning.
Let’s start with the classic. The .22 LR has probably accounted for more groundhogs than just about anything else out there. Farmers have been leaning a .22 behind the truck seat for generations, and for good reason.
Inside about 50 to 75 yards, a .22 LR is perfectly capable if you do your part. It’s cheap to shoot, easy on the ears, and extremely accurate in a good rifle. Around barns, fence lines, and smaller properties, it’s still a solid choice. The catch is distance. Once you start stretching things past 100 yards, the little rimfire runs out of steam pretty quickly.
Suppressor Suggestion: BANISH 22
Designed for rimfire rifles and pistols, .22 caliber and smaller. The BANISH 22 is as close to “Hollywood Quiet” as you can get without sound effects. It is great for groundhogs.
If you like rimfires but want more reach, the .17 HMR is a fantastic groundhog cartridge. This little round is fast, flat-shooting, and incredibly accurate. For shots in the 100–150 yard range, the .17 HMR really shines. The light, high-velocity bullets hit varmints hard and tend to deliver quick results when the shot placement is right.
It’s also one of the most fun cartridges to shoot because recoil is practically nonexistent. You can usually watch the hit right through the scope. Just keep an eye on the wind. Those tiny bullets can drift when the breeze picks up.
Suppressor Suggestion: FN Catch 22 Ti
Mounting to rimfire hosts is fast and repeatable with the direct-thread ½ in. x 28 mount. The user-serviceable blast baffle and baffle stack delivers an exceptionally quiet and smooth shooting experience on 22 LR, 22 MAG, 22 WMR and 17 HMR firearms.
Some groundhog setups involve wide-open farm country where the shots can really stretch out. That’s where the .22-250 Remington earns its reputation.
This cartridge is fast - really fast. The high velocity gives it a laser-flat trajectory, which makes longer shots much more forgiving. It also carries enough punch to anchor a woodchuck even when the distance starts creeping past 300 yards. The trade-off is more noise and a little more recoil, but if long-range varmint shooting is your thing, the .22-250 is hard to top.
Suppressor Suggestion: BANISH 30-V2
Since the .22-250 is so versatile, it makes sense that you can use the most versatile suppressor on the market - The BANISH 30-V2 - to suppress one. This HUB-mount, .30 caliber can works well with any caliber from .300 WBY down.
If you like your groundhog hunting with a little extra reach and a lot of authority, the 22 Creedmoor is hard to beat. This hot-rod .22 caliber round pushes sleek, high-BC bullets at blistering speeds, which means flatter trajectories and less wind drift when that whistle pig pops up way out in the hayfield. It hits harder than smaller .22s, too, giving you decisive results even at extended ranges.
For hunters who enjoy stretching things out and watching impacts through the scope, the 22 Creedmoor delivers laser-beam performance and plenty of varmints-don’t-argue knockdown power. It’s basically a long-range groundhog problem solver.
Suppressor Suggestion: BANISH VRMT 223 Ti
The BANISH VRMT 223 Ti is the first suppressor rated for the 22 Creedmoor. It is all titanium and can handle anything you can throw at it and more.
At the end of the day, the best caliber for groundhog hunting depends on the kind of hunting you’re doing.
The good news is that groundhog hunting doesn’t require anything fancy—just a good rifle, solid optics, and the patience to wait for that woodchuck to stand up and look around. And when he does, you’d better be ready.
