A big-bore hunting air rifle is a PCP that throws a heavy .35, .45, or .50 projectile, not a tin wadcutter. Most of the guns here need a tank or a compressor you already own, and the useful shot string gets short once the bore gets wide. A few listings are air shotguns, a .25 lever gun, or a pump .22. They do a real job, just not the same one.
What the caliber number changes
Velocity only means something next to the projectile the maker timed. Seneca’s Dragon Claw II is the clearest example: a 177 grain .50 round ball is quoted at 860 Feet/second, and a 336 grain flat-nose slug out of the same rifle is quoted at 340 feet/second. Same gun, very different hit. Read the ammo line that matches what you will actually shoot, and don’t treat the biggest fps on the page as the hunting load.
.35 and .357 are the light end of this list. .45, .457, and .50 are the heavy end. A .25 and a .22 showed up in the catalog too. They belong in the comparison so you can see what you are not buying.
How many shots a fill really buys
Fill pressure splits the PCPs. The Hammer is the 4500 psi gun, with a 24 cubic inch carbon fiber tank. The Senecas, the Bulldogs, and the Double Shot are 3000 psi guns. Shot counts fall off as the bore grows. The .35 Carnivore is the outlier Hatsan rates at up to 12 shots per fill. The .457 Bulldog is up to 3 effective shots, and the Double Shot is up to 5 good shots.
Don’t plan a long walk on a three-shot .50 unless you can refill. The Dragonfly is the only rifle here with no tank at all. You pump it, from 3 to 15 strokes, and it is a .22.
Rifle, bullpup, or air shotgun
A bullpup puts the action back by your shoulder so the gun can stay shorter. Benjamin quotes 36 inches overall on both Bulldogs. The Piledriver is also a bullpup, but the size line lists 46.5 inches, so it is not the compact one. Wood-stocked Senecas shoulder like a traditional rifle and carry a loudness mark of 5-High.
The Double Shot and the Wing Shot II are smoothbores with chokes. They throw shot, a round ball or bullet, or an air bolt, depending on how you set them up. If you want spin on a hunting slug, buy a rifle whose listing says the barrel is rifled.
Best Big-Bore Hunting Air Rifles
1. Umarex Hammer .50 Caliber PCP
Start here if you want a regulated .50 that Umarex bills as the most powerful production air rifle, built to dump energy in the target instead of carrying it through. Umarex quotes .50 pellets at up to 1130 fps from an ultralight 4500 psi, 24 cubic inch carbon fiber tank, and calls the rifle very quiet. You get two 2-shot linear mags, a straight-pull bolt with a 2-pound pull weight and 2 inches of travel, a mag lock-out that will not fire without a mag, a trigger-block safety, M-LOK slots, and a Picatinny rail for optics.
Umarex’s own line gives you 4 full power regulated shots plus 1 finishing shot, then puts 4 shots total in parentheses. Plan the hunt around the smaller number until you see what your tank actually does.
Best for: Regulated .50 with a very short shot string
Listed at $999.99 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy.
2. Seneca Dragon Claw II .50
If you want one wood-stocked .50 timed for round ball, heavy slugs, and air bolts, this is the Dragon Claw II. Seneca quotes .50 caliber 177 grain round balls up to 860 Feet/second, 336 grain flat nose slugs up to 340 feet/second, and Seneca Air Bolts up to 600 Feet/second. Dual air chambers hold 500 cc total, with a 3,000 psi max fill, a built-in gauge, and a male Foster fill fitting on the rifle.
It is a single-shot bolt with a longer cocking handle and a rifled barrel. Sights are a fixed front and a fully adjustable removable rear, plus an 11 mm rail that Seneca says is for compact scopes only. The hardwood Monte Carlo stock has a checkered forearm and grip and a raised right-hand cheekpiece. Seneca’s spec line puts overall length at 42.1 inches, weight at 8.5 pounds, trigger pull at 7.5 pounds, and loudness at 5-High, suggested use hunting.
Best for: .50 ball, slug, or air bolt from a wood stock
Listed at $799.99 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy.
3. Benjamin Bulldog .457 PCP Bullpup
Carry this when you want a .457 bullpup short enough for a blind and a 5-shot magazine you can load without fuss. Benjamin quotes a short 36-inch overall length, a 3000 psi reservoir with a gauge, up to 3 effective shots per fill, and velocities up to 760 fps. The air compressor is not included.
You also get a baffle-less sound-trap shroud, a rifled steel barrel, a muzzle adapter with M18 threads, and a 26-inch Picatinny rail. The stock is synthetic. Three shots is a stand rifle, not an all-day string, so keep the fill plan as close as the quarry.
Best for: Short .457 bullpup with a 5-shot mag
Listed at $963.49 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
4. Hatsan BT65 Big Bore Carnivore .35
Choose the Carnivore when .35 is enough gun and you want more shots per fill than the .50s on this list. Hatsan quotes lead at 760 fps and 105 FPE, and says velocity and energy move with pellet weight, shape, material, temperature, and elevation. The air cylinder is 255 cc, with up to 12 shots per fill, a quick-fill nozzle, and a discharge cap.
It is a side-lever repeater with QuietEnergy and an integrated moderator, plus the Quattro two-stage match trigger, which is fully adjustable. The rail takes Weaver or 11 mm mounts, and there are no open sights, so budget a scope with the rifle. Listed weight is 9.7 pounds.
Best for: .35 repeater with the most shots per fill
Listed at $493.99 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
5. Hatsan Piledriver Big Bore PCP .50
The Piledriver is the single-load .50 for a shooter who cares about the foot-pound number Hatsan prints. It is a bullpup with manual loading, a side lever, and a gas-piston hammer spring. The cheek rest locks and adjusts for elevation. The soft rubberized butt pad adjusts for elevation and fit angle. The long rail takes both 11 mm and Picatinny mounts.
Hatsan quotes a max velocity of 850 fps and muzzle energy of 800 ft/lbs. The size line lists 46.5 inches long and 10 pounds. That length is a full rifle even with the bullpup layout, so measure your blind before you assume it will tuck in like the Bulldogs.
Best for: Single-load .50 with an 800 ft/lbs quote
Listed at $999.95 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
6. Seneca Double Shot .50 Double Barrel
Two smooth .50 barrels, one ready behind the other: that is the Double Shot’s job. Seneca quotes .50 shotshells up to 1130 feet per second, .50 round balls up to 640 Feet/Second, and air bolts up to 425 Feet/Second. Shot capacity is 2. The 244 cc cylinder fills to 3000 psi and is rated up to 5 good shots per fill, with a male Foster fitting and an on-board gauge.
Chokes thread on and come off for air bolts or slugs. Seneca says the choke reduces the inner barrel diameter from .494 inch to .486 inch. The stock is ambidextrous hardwood, the two-stage trigger is not adjustable, and there is a rubber buttpad. You get a front bead and no rear sight, with an optional 11 mm rail if you want glass. Overall length is 43.5 inches, weight is 8.55 pounds, and loudness is 5-High.
Best for: Two-barrel .50 for shot, ball, or bolts
Listed at $956.60 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
7. Seneca Dragonfly Mk2 .22 Multi-Pump
Skip the air tank entirely and you are looking at the Dragonfly, a .22 you pump by hand. It is not a big-bore hunting rifle. Power is variable from 3 to 15 pumps, and the butterfly pump is meant to keep the effort the same each stroke. The synthetic stock is listed at 6.35 pounds, with a textured rubber buttpad.
Seneca quotes alloy pellets to 840 fps in .22. The same line also quotes 950 fps in .177, which this .22 listing does not shoot, so plan around the .22 figure. You get a 1/2 inch UNF threaded muzzle, an 11 mm rail, a fixed fiber-optic front sight, an adjustable rear sight, one magazine, and a single-shot tray.
Best for: Pump .22 when you do not want a PCP
Listed at $169.97 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy.
8. Air Venturi Wing Shot II .50
Hunt upland one outing and a larger animal the next, and the Wing Shot II is built for that switch. Don’t leave the choke screwed in if you are shooting lead bullets. Air Venturi says to unscrew it first. With .50 bullets they quote 760 fps and fpe exceeding 245, and they say that is enough for a javelina or coyote with a well-placed shot. No. 8 shot is quoted at 1130 feet per second and 360 foot pounds, with spreads of 12 inches at 20 yards. Air bolts are quoted up to 500 fps and 238 FPE. A separate line quotes .50 pellets up to 1150 Feet/Second.
The reservoir is a single 244 cc bottle with a gauge. The stock is ambidextrous hardwood, the barrel is a smoothbore, and you get a ventilated rib plus a bead and no rear sight. Listed weight is 7.4 pounds.
Best for: .50 that switches between shot and bullets
Listed at $803.27 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
9. Seneca Eagle Claw Carbine Lever Action
A lever gun in .25 is a different hunt than a .50. The Eagle Claw is that lighter repeater. The listing gives caliber 0.25, velocity 920.00 ft/sec, a 1-year limited warranty, and calls it a powerful lever-action repeater from Air Venturi.
Shot count, fill pressure, and weight are not on the captured sheet, so check those before you buy if they decide the rifle for you.
Best for: Lever-action .25 when .50 is more gun than you need
Listed at $797.09 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
10. Benjamin Bulldog BPBD3S .357
Left-handed or right, the .357 Bulldog keeps the short bullpup and flips the sidelever. Benjamin quotes a 36-inch overall length, a reversible sidelever bolt with a lever safety, a baffle-less sound trap, and a rifled steel barrel at up to 910 fps. The rail is 26 inches of Picatinny. The box includes a 5-shot magazine and a cleaning kit. Listed weight is 9.2 pounds.
Same short layout as the .457 Bulldog, smaller bore, and a higher velocity quote. Pick it when .357 is the hunting caliber you already shoot and you want the lever on your strong side.
Best for: Ambidextrous .357 bullpup with a 5-shot mag
Listed at $1,329.35 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
11. AirForce Texan SS Big Bore Air Rifle
A .357 PCP with a Spin-Loc tank and a velocity quote over the other .357 here is the Texan SS’s pitch. AirForce lists caliber 0.357, velocity 1060.00 ft/sec, weight 8.45 pounds, a one-year limited warranty, and the Spin-Loc tank.
The captured sheet stops there. No shot count, no fill pressure, and no length. If those three decide the buy, get them from AirForce before you order.
Best for: .357 PCP built around a Spin-Loc tank
Amazon currently shows this one out of stock — a temporary supply gap on a product that is still made, so it is worth checking back.
12. Hatsan Hercules Bully .45
Between the .35 Carnivore and the .50 Piledriver, the Hercules Bully is the .45 with a carbon-fiber bottle in the forearm. Hatsan quotes lead pellets at 850 fps and 290 FPE, with the usual note that results move with pellet, weather, and elevation. The bottle is 480 cc. QuietEnergy includes an integrated moderator, and the two-stage trigger adjusts for travel and load.
The combination rail is 21 inches and takes both 11 mm and Picatinny mounts. Sights are detachable, folding, and adjustable, with fiber optics, so you can hunt with them or pull them for a scope. It is a side-lever bullpup. Listed weight is 10.3 pounds, the heaviest figure on this list.
Best for: .45 bullpup with a 480 cc carbon-fiber bottle

Frequently Asked Questions
Do I need a compressor?
Every PCP here needs a high-pressure fill, either from a compressor or from a scuba-style tank and the right fittings. The Dragonfly is the exception. You pump that .22 by hand, anywhere from 3 to 15 pumps. The Bulldog .457 listing says the air compressor is not included, and the same is true of the others.
Is a .25 a big bore?
Not next to the rifles this guide is about. The Eagle Claw is 0.25 at 920.00 ft/sec. The big-bore guns here start at .35 and run through .50. Buy the Eagle Claw for a lever-action hunt in a smaller caliber, not because you wanted a .45 or a .50.
Which ones are air shotguns?
The Seneca Double Shot and the Air Venturi Wing Shot II. Both are smoothbores with removable chokes, a bead, and no rear sight. The Wing Shot II tells you to unscrew the choke before lead bullets. Leave it on for No. 8 shot, which Air Venturi quotes at 1130 feet per second with spreads of 12 inches at 20 yards.
How many shots should I expect per fill?
Read the line for that model. The .457 Bulldog quotes up to 3 effective shots, the Hammer’s line disagrees with itself around 4, the Double Shot quotes up to 5 good shots, and the .35 Carnivore quotes up to 12. A bigger bore spends the air faster. Bring a refill if the hunt is longer than one stand.
If you want the hardest .50 number on the page and you will live with a short string, compare the Hammer’s 1130 fps quote with the Piledriver’s 800 ft/lbs. They are not the same kind of spec, so match the one you can use. If you want more shots and a smaller bore, take the Carnivore in .35 or the .357 Bulldog. If the hunt is birds or squirrels in the brush and you still want a .50 bullet option, take the Wing Shot II or the Double Shot and set the choke for the load. If you do not own an air supply yet, the Dragonfly is the only rifle here that does not need one, and it is a .22 pump, not a big bore. Check fill pressure, shots per fill, and whether the barrel is rifled before you pay.
