The world of air rifles has evolved dramatically in recent years, and nowhere is that more evident than in the big bore air rifle category. Today’s large caliber pellet guns in .30, .357, .45, and even .50 caliber deliver genuine hunting power that can ethically take deer, wild boar, and other medium-to-large game—all without the ear-splitting report or expensive ammunition of traditional firearms.
Whether you’re looking for a .45 air rifle for deer hunting, a quiet option for predator control on your property, or simply want to explore the impressive capabilities of modern PCP technology, this comprehensive guide covers everything you need to know about big bore air rifles in 2026. We’ll break down the best models across different calibers and price points, explain the legal landscape for air rifle hunting, and help you understand the energy requirements for taking various game animals humanely.
What Makes an Air Rifle “Big Bore”?
In the airgun community, “big bore” generally refers to any air rifle with a caliber of .30 or larger. This distinguishes them from standard air rifles in .177, .22, and .25 caliber, which are primarily designed for target shooting, plinking, and small pest control.
The jump from .25 caliber to .30 caliber and beyond represents a fundamental shift in capability. While a powerful .25 caliber air rifle might generate 50-60 foot-pounds of energy (FPE), big bore air rifles routinely produce 100-500+ FPE—putting them firmly in the territory of traditional firearms for hunting applications.
Common Big Bore Calibers
-
.30 Caliber (7.62mm): The entry point into big bore territory. Rifles in this caliber typically produce 60-120 FPE, suitable for coyotes, raccoons, and similar-sized game. For a detailed look at the top options in this caliber, see our guide to the best .30 caliber pellet guns.
-
.357 Caliber (9mm): A popular middle ground offering 100-200 FPE. Excellent for javelina, feral hogs, and deer at moderate ranges.
-
.45 Caliber (11.43mm): The most popular caliber for deer-sized game. Quality .45 air rifles produce 200-500 FPE, making them genuine big game tools.
-
.50 Caliber (12.7mm): The largest commonly available caliber, capable of 500+ FPE. Designed for the largest game legally huntable with air rifles.

Energy Requirements for Different Game Animals
Understanding foot-pound energy requirements is crucial for ethical hunting with any big bore air rifle. Shooting game with insufficient power leads to wounded animals and poor outcomes for everyone involved. Here’s what experienced air rifle hunters recommend as minimum energy levels at point of impact:
Minimum Energy Guidelines by Game Type
| Game Animal | Minimum FPE | Recommended Caliber |
|---|---|---|
| Squirrels, Rabbits | 12-25 FPE | .22-.25 |
| Raccoons, Opossums | 40-60 FPE | .25-.30 |
| Coyotes, Foxes | 60-100 FPE | .30-.357 |
| Javelina, Small Feral Hogs | 100-150 FPE | .357-.45 |
| Whitetail Deer | 150-250 FPE | .45-.50 |
| Large Feral Hogs | 200-350 FPE | .45-.50 |
Important: These are minimum recommendations for ethical kills with proper shot placement. Always verify energy at your intended shooting distance, as air rifle projectiles lose energy more rapidly than firearm bullets. A rifle producing 200 FPE at the muzzle might only deliver 120 FPE at 75 yards.
Slugs vs. Pellets: What to Shoot in Big Bore Air Rifles
One of the biggest decisions facing large caliber pellet gun owners is whether to shoot traditional pellets or modern airgun slugs. Both have their place, and understanding the differences will help you make the right choice for your application.
Diabolo Pellets
Traditional diabolo pellets feature a waisted shape with a hollow skirt that expands upon firing to seal the barrel. Even in big bore calibers, pellets offer several advantages:
-
Superior short-range accuracy: The high drag coefficient that limits range actually improves stability under 50 yards
-
Lower cost: Generally less expensive than quality slugs
-
Safer backstops: Pellets shed energy quickly, reducing ricochet danger
-
Better expansion: Hollow point pellets expand reliably at big bore velocities
Best For: Shooting under 50 yards, pest control, situations requiring energy dissipation
Airgun Slugs
Slugs look similar to firearm bullets and are designed for optimal long-range performance in airguns. They’ve become increasingly popular in big bore rifles:
-
Superior long-range ballistics: Higher ballistic coefficient retains energy and resists wind deflection
-
Greater penetration: Solid construction and retained energy punch through tissue more effectively
-
Flatter trajectory: Less drop at extended ranges for easier holdover
-
Better terminal performance on large game: Deep penetration reaches vital organs
Best For: Hunting beyond 50 yards, large game animals, situations requiring deep penetration
The Practical Recommendation
For most big bore air rifle hunting applications, slugs have become the preferred choice. The extra range and penetration capability outweigh the modest accuracy advantage pellets offer at close range. Many hunters keep both on hand—pellets for backyard pest control and slugs for serious hunting.
Air Rifle Hunting Regulations by State
Regulations for hunting with air rifles vary dramatically across the United States. While some states fully embrace air rifle hunting for big game, others restrict or prohibit it entirely. Here’s the current landscape for hunting deer and similar game with air rifles:
States Allowing Deer Hunting with Air Rifles
The following states explicitly permit deer hunting with air rifles meeting minimum caliber and/or energy requirements (always verify current regulations before hunting):
-
Texas: .30 caliber minimum, 150gr minimum, 800 fps or 215 FPE; PCP only (TPWD)
-
Missouri: Minimum .40 caliber, 215-grain minimum bullet weight
-
Alabama: .30 caliber or larger
-
Arizona: No restrictions on air rifles for small game; check big game rules
-
Arkansas: .40 caliber minimum for deer
-
Florida: Air guns legal for deer on private land
-
Georgia: .30 caliber or larger
-
Indiana: .357 minimum caliber, certain seasons
-
Michigan: .35 caliber or larger, PCP only (MI DNR)
-
North Carolina: Check current regulations for specific requirements
-
Oklahoma: .30 caliber minimum
-
Virginia: .45 caliber or larger, 200 FPE minimum at muzzle
States with Restrictions or Prohibition
Many states either prohibit air rifle hunting for deer or have no specific provisions allowing it. When state regulations don’t specifically permit air rifles, they’re generally considered illegal for big game hunting. States like California, New York, and many northeastern states have restrictive regulations regarding air rifle hunting.
IMPORTANT: Hunting regulations change frequently. Always consult your state’s current fish and game regulations before hunting with any air rifle. This information is provided as a general guide only and should not be considered legal advice.
Essential Accessories for Big Bore Air Rifle Hunting
Your .45 air rifle or other big bore represents just part of the investment needed for successful hunting. Here are the accessories that serious big bore hunters consider essential:
High-Pressure Air Source
Big bore air rifles consume significant amounts of air. You’ll need a reliable way to fill your rifle:
-
Hand Pump (~$50-150): Cheapest option but labor-intensive. Not practical for high-pressure rifles over 3,000 PSI
-
Scuba Tank (~$200-300 used, plus fills): Good middle ground; typically provides 15-25 fills per tank
-
Portable Compressor (~$300-600): Best convenience for shooters who practice regularly
-
Shoebox Compressor (~$400-700): Affordable, reliable option for most big bore owners
Quality Optics
Big bore hunting typically occurs at ranges where precise shot placement matters. A quality scope rated for air rifles (which handle double-recoil differently than firearms) is essential. Budget $150-400 for a scope appropriate for your rifle’s capability.
Projectiles
Stock up on quality ammunition before hunting season. Big bore slugs and pellets cost significantly more than standard calibers, so budget accordingly. Expect to pay $20-50 per 100 rounds for quality hunting projectiles in .45 caliber.
