Idaho’s short-range weapons regulations, set out in Idaho Administrative Code rule 13.01.08.407, allow six weapon types during any season the Fish and Game Commission designates as short-range only: shotguns firing slugs or #00 or larger buckshot, muzzleloaders, bows, crossbows, handguns firing straight-wall centerfire cartridges, and pre-charged pneumatic airguns.1Legal Information Institute. Idaho Admin Code r 13.01.08.407 – Special Weapon Seasons – Short-Range Weapons Each carries its own caliber, draw-weight, or ammunition rules, and several of those rules shift depending on the species you’re after.
The Six Legal Weapon Types
Anything outside these six categories is unlawful during a short-range season, no matter how short its effective range might be in practice.
- Shotguns. Any shotgun firing slugs or #00 (double-aught) or larger buckshot. The rule sets no restriction on bore type or gauge, and it excludes birdshot and smaller buckshot.
- Muzzleloaders. Any muzzle-loading firearm that meets the caliber minimum for your species. Ignition system is not restricted here, so modern inlines with 209 primers are fine.
- Bows. Any bow with a peak draw weight of at least 40 pounds up to or at 28 inches of draw.
- Crossbows. Any crossbow with a peak draw weight of at least 150 pounds.
- Handguns. Any handgun firing straight-wall centerfire cartridges not originally developed for rifles. Common qualifying rounds include.44 Magnum,.454 Casull, and.460 S&W. Bottleneck rounds like.30-30 or.223 do not qualify.1Legal Information Institute. Idaho Admin Code r 13.01.08.407 – Special Weapon Seasons – Short-Range Weapons
- Airguns. Any pre-charged pneumatic airgun that propels a projectile with unignited compressed air or gas. Airguns may not fire shot or arrows under this category.
A few silences in the rule are worth catching. There is no barrel-length cap for handguns and no gauge restriction for shotguns. The handgun requirement is done by cartridge design, not the firearm itself: the test is whether the round was designed as a handgun cartridge first, which is how lever-action rifles chambered in pistol calibers get excluded.
Caliber Minimums by Species
Getting the wrong caliber into the field is one of the easiest ways to pick up a citation, and both muzzleloaders and airguns split into two tiers depending on what you’re hunting.
Muzzleloaders
- .45 caliber or larger for deer, pronghorn, mountain lion, and gray wolf.
- .50 caliber or larger for elk, moose, bighorn sheep, mountain goat, and black bear.
These minimums apply specifically during short-range weapon seasons.1Legal Information Institute. Idaho Admin Code r 13.01.08.407 – Special Weapon Seasons – Short-Range Weapons
Airguns
- .35 caliber or larger for deer, pronghorn, mountain lion, and gray wolf.
- .45 caliber or larger for elk, moose, bighorn sheep, mountain goat, black bear, and grizzly bear.
The 2026 Big Game Seasons and Rules proclamation adds grizzly bear to the larger-caliber airgun tier.2Idaho Department of Fish and Game. Idaho Big Game 2026 Seasons and Rules
Short-Range Muzzleloader Rules Are Not the Same as Muzzleloader-Only Rules
This trips up hunters who move between Idaho’s two special weapon seasons. During a muzzleloader-only season, the firearm must use a flint, percussion cap, or musket cap, and any portion of the cap must be exposed when the weapon is cocked. That rules out most modern inlines with closed-breech 209 primer systems.
Short-range seasons are far more permissive. Any hammer type is allowed, including plunger or bolt-style inlines, and any ignition system is allowed, including closed-breech systems with 209 primers. If you own a modern inline that does not qualify for a muzzleloader-only hunt, it almost certainly qualifies for a short-range hunt as long as it meets the caliber minimum for your species.
Scopes and Electronic Devices
Idaho’s restrictions on weapon-mounted electronics apply during short-range hunts along with every other season. Battery-powered or tritium-lighted reticles inside a scope are allowed. Other electronic devices attached to or built into the firearm or scope are not, which takes rangefinding scopes, thermal optics, and ballistic-calculating scopes off the table.
Handheld electronics are a separate matter. A separate rangefinder or GPS unit is fine. On archery equipment during any season, electronic or tritium-powered devices attached to a bow, arrow, or bolt are unlawful, with lighted nocks as the one exception.
Where Short-Range Zones Apply
The Fish and Game Commission designates specific game management units, or portions of units, for short-range seasons through its annual proclamation. These zones tend to sit where residential development pushes up against huntable habitat, and limiting projectile range reduces the chance of a round reaching an occupied area. Boundaries change from year to year.
The 2026 Big Game Seasons and Rules booklet identifies each short-range zone by unit number and describes the boundaries using landmarks like highways, rivers, and ridgelines.2Idaho Department of Fish and Game. Idaho Big Game 2026 Seasons and Rules Some units are entirely short-range; others split along a road or geographic feature, with short-range rules on one side and different rules on the other. Idaho Fish and Game’s online Hunt Planner lets you search by species and weapon type to confirm whether a unit carries short-range restrictions and on which dates.
Penalties for Using the Wrong Weapon
Weapon violations are not among the specific infractions listed in Idaho Code 36-1401, so they default to misdemeanor status.3Idaho State Legislature. Idaho Code 36-1402 – Penalty – Infraction – Misdemeanor – Felony – Revocation of License – Disposition of Moneys A conviction can bring a fine of $25 to $1,000, up to six months in jail, or both.
If the violation also involves illegally taking an animal, the statute adds species-specific minimum fines on top of the base penalty:
- Bighorn sheep, mountain goat, or moose: $500 minimum per animal.
- Elk: $300 minimum per animal.
- Any other big game animal, including deer, pronghorn, black bear, and mountain lion: $200 minimum per animal.
Those minimums stack, so illegally taking an elk with a prohibited weapon during a short-range season starts at $300 before the court considers additional fines or jail time.3Idaho State Legislature. Idaho Code 36-1402 – Penalty – Infraction – Misdemeanor – Felony – Revocation of License – Disposition of Moneys The court can also revoke hunting, fishing, or trapping privileges for up to three years on any fish and game conviction, and an animal harvested with an unlawful weapon can be seized by the state.
