The Benjamin Bulldog .457 gives you even more of what you loved from the popular Bulldog series so you can take bigger game than you could before. You get speeds up to 760 fps and power up to 450 fpe with this upgraded version because it uses .457 slugs or pellets, meaning you'll have over twice the power of the smaller caliber version.

The added power of this air rifle comes from the longer air cylinder it uses, but you'll still get up to three shots at lethal power, and the overall length of the gun is still very maneuverable at 36.38", which is less than half an inch longer than the .357. You'll also appreciate the accuracy of this rifle, because it uses a precision rifled barrel.

The Benjamin Bulldog .457 gives you quieter shots in spite of the fact that it's so powerful because it uses a baffle-less SoundTrap system, and there's an M18 threaded muzzle adapter that lets you add a moderator for shots so quiet your quarry won't know where you are.

The features hunters know and love from the .357 version are here in the .457 too, like the reversible sidelever that makes it left hand friendly, plus the extended 26" Picatinny scope rail that makes it a breeze for you to add large scopes or other sighting accessories. Plus, you get front and rear sling studs, a ridged rubber recoil pad, and a textured pistol grip, which all make this gun comfortable and easy to use and carry.

This is one dog that definitely hunts, so if you're ready to step up to a bigger bore version of an already great gun with more power to take down more game, get the Benjamin Bulldog .457 from Airgun Depot now.

What is this thing gonna do with a HUMA regulator in it? Just saying

I had the original.357 Bulldog I put in a HUMA Regulator in it. I would set it at 2100psi and I was still getting 7 shots at 886 fps.with 110 gn.NSAs.

I didn't extend the fill tube, but it's a heck of lot better than the massive power curve, that was unexpected from what ever weight projectiles you were putting in it.

By BenjaminNovember 23, 2022

Compact,feels perfect on the pull up trigger pull is great,Been shooting 350 grain and 400 grain very accurate blew apart a concrete block,this is not your grand daddy's pellet gun although haven't shot a deer yet with it very confident with a good shot it will down most anything your shooting at

350 grains benjamin ammo doesn't fit in magazine bit overall not many negatives

Happy with my purchase :)

SAFETY with ALL big-bore rifles...

The size and weight get's a little weighty if you're not used to it yet. The ease of use, firepower and it look's V-E-R-Y futuristic... I love it! Plan on complimenting it with it's big brother, .50 cal real soon.

The refilling valve protector. The locking lip is easily broken and the small latch WILL fall into the filling chamber and be trapped in the well which you can't get out. The weapon has to be sent out for repairs. Just got one last we and while trying to remove for refilling, it broke off. Haven't even had it for a week. Now trying to get it repaired already.

Got this in a 45 ah had to build the scope up so it was usual for me but it was a very well-made gun it shoots well and I would recommend it to anyone

Powerful good at 75 yards

Not a thing

By AaronUSADecember 28, 2021

This rifle takes getting used to. For an air rifle, it's a bit heavy... it felt awkward to use, at first... but, now that I've put several rounds downrange, I like her!

Very accurate! I was able to dope the scope for 25 yds, and these are the results...

The rubber recoil pad sucks! It falls off way too easily!

By TonyUSADecember 21, 2021

I have owned the Bulldog for 4 years. I purchased a silencer from a group in Fl. The silencer has deceased the sound level by 75%. Recommended when in area with neighbors. Regarding the review by Kerop.,This page is about rating air guns not your minimal ability to grade another person grammar and writing ability. FYI, your paragraph was not grammatically correct in many aspects. For starters this is called a , (coma)

lately large caliber pellets jamming, few pellets appeared out of round

Was just shopping. Looks good.

By CraigUSAOctober 4, 2021

Update, finally got to go shoot this amazing gun. Didn't want to shoot it in the backyard like the smaller calibers I own. So went to my friends farm with my wife and her new Savage 22. Yikes this gun is no JOKE! See attached photos. 3 1/8 inches into a 6×6 pressure treated hard Chunk of wood. All I can say is it's AWESOME, GET ONE and be very sure of your backstop. Love it, love it, love it! Green arrow shows direction of travel. Target at 50 yard's. Can't wait to go again!

I like just about everything but see cons.

Not real keen on the plastic safety.

Can Airgun Depot add a Huma regulator and a Donny FL suppressor with adapter upon request and order of the upgrades?

asked Francisco from

Airgun Depot does not sell Huma regulators or have a custom shop.

Adam from USA

What type of Huma regulator can the 257 caliber take, and roughly the price to order.

asked Francisco from

The 3,000 psi cylinder fill equates to 206.7 Bar pressure. Is there an add on tank that is more than the 440cc and can be filled to a higher pressure?

asked Francisco from

What is the active rifling length of the barrel that the pellet travels, minus any forward baffles or such for the 257 caliber?

asked Francisco from

How many rounds on a full tank

asked Jeff from USA

3 good shots in .457.

Adam from USA

can a guy put a donny fl on this?

asked Paul from USA

Will the new airbolt work in the Benjamin bulldog

asked Carlton from USA

Can you buy a suppressor for this weapon, and where can I purchase one?

asked Larry from USA

What is the max. fill pressure?

asked terry from USA

How is moderate fitted

asked Tom from USA

If you order from Donnyfl you have to buy the adapter that replaces the end cap and the moderator screws right onto the threaded adapter. Very easy. I have the Emperor moderator and it does a good job.

Ronald from USA

do the bull pup shoots arrow bolts

asked jim from USA

do the bull dog pup shoot arrow bolts

asked jim from USA


Richard from USA

Does this come with any means of filling the tank? Or is that a separate purchase?

asked Dan from USA

NO PUMP(not easy), Bottle(expensive) or compresure ($200+to thousands) pick 1

Richard from USA

Who covers the 5 year warranty on this? Also is there a list of what ammo can be shot through this?

asked Bryant from USA

Helo Can it be disassembled ? Can I load with an air compressor or manualy ?

asked Vítor

It can be disassembled. You can use an air compressor as long as it has a 3000 psi output.

Ronald from USA

Which gun is louder... the bulldog or the condor ss?

asked Steve

Definitely the bull dog!


will bulldog357 might loud but other like air force and taxen much louder

Billy from USA

They are both rated with 4 medium-high. About about as loud as punching your leg


bulldog is way louder..

OneEyedJack Great Falls MT.

This gun is much louder than the Condor SS which is a shrouded gun. This gun is as loud as the AirForce Texan (which is unshrouded) in my opinion.


what do you think of this rifle for power and accuracy and what is the best clean kill to date

asked hamish

150 lb hog at 50 yrds. Nosler went through lungs above shoulder and was bullet seen bouncing off water in lake behind hog. Hog dropped in 30 feet.

Tony from USA

will have seen video of hunting with bulldog 357 and kills are clean and fast so this make good survival gun and practices gun maybe home defends I am every impress on this air gun I would like own one but I will save one up too just that

Billy from USA

As far as I know it is 900fps with a 145 grain 357. Pellet And the latest recorded trophy was a white-tale deer in south Carolina


I have tried lots of pellets and pure lead cast bullets . For pellets the H&N Grizzly 82 gr. hollow points are good for small game , target shooting ,I use them for sighting in new sights ,scopes and red dots . The sizing of the pellet is a bit smaller than .357 there .35 caliber .What makes them shoot able is the rear is concave , I've done some tuning and tinkering with one of my Bulldogs so the extra oomph opens up the rear of the pellet and expands the lead against the inner barrel sealing it enough for 900 plus psi ! close to 145 fpe .My favorite's for my own pure lead cast bullets are .358 Lee 125 gr round flat top 869 fps / 220 fps ,and my self defense round is the Lee 2 cavity ,358 diameter 158 round flat tip ( 163 gr ) with pure lead at close to 800 fps for 231 fpe my best kill to date was dead center shot through both sides of my outdoor grille !lol clean hole going in close to a quarter coming out.

Timothy from USA

35lb coyote at 35 yards


Hammish if u look at YouTube there is a guy with a wildabeast
