Oklahoma Hunting Laws
Oklahoma sets no minimum caliber for deer rifles or handguns — any centerfire firing a bullet of at least 55 grains is legal, and suppressors are allowed on both public and private land. Deer shotguns must be centerfire firing a single slug; rimfire and fully automatic firearms are not legal deer weapons.

Air Gun
1 rule| Species | Rule | Citation | Verified |
|---|---|---|---|
| White-tailed / Mule Deer |
Oklahoma's air-powered 'arrow rifle' (airbow) must maintain at least 2000 psi with a visible gauge and requires a one-time Arrow Rifle Permit; this fires an arrow rather than a pellet, so the 2000 figure is pressure (psi) not muzzle energy — flagged for review of the correct unit/value_numeric mapping. Legal only during rifle seasons, not archery season.
