I think I would go nuts keeping track of all the screws, springs and pins. Guess that is why we have guys like you to modify our Bulldogs. I have always been great at taking things apart. Putting them back together...... Good work. Thanks for the vid.
bluewater454 I understand that completely. After you've done it a dozen times it's no big deal. I hint for the beginner tinkerer is lots of pictures. Sometimes the mind can't remember all of the small parts but having a picture to reference it makes a big difference when putting it all back together.
my 357 is a dream. I bought a 457 commander and hung it on my wall. I like to look up and nod, knowing that that .457 perfect slug I cast.. is protectiing my home.

Great teardown video, could please identify each tool size used to remove screws! You did in the beginning then You started adding additional tools that were unaccounted for regarding size I.e that big daddy Allen wrench set. Also I purchased a Mega moderator and the barrel spacers will you do a video on proper install and recommended spacing?
Stupid question. Just put my first mag in the bulldog... pulled the cocking lever back and kept pressure on trigger essentially "decocking" it with a full mag in...now what?? Can the pellet be fired?? Or if I cock it again to fire will it double load?
If you cock it again it will double load. Best option is to open bolt and remove mag then close bolt and fire. Other option is to hold the rotating section of the mag while you cock it and keep it from rotating. Then close the bolt on that open cylinder.
Matt I’m curious as if there is a much lighter popit spring? I agree there should be one in place to help close the popit for the purpose of getting air into the rifle but if it has a fairly heavy spring it will assist in closing quicker when a shot has been fired
Hi matt so im stuck my buddy was shooting my gun double cocked it and loged a round in the barrel and then somehow he made it so I cant cock it anymore the sear still works just not when the gun is assembled
lol 3rd time i watched this one, but first time i liked it.! this is AWESOME. cause i can tear it down send you parts you dip them, i pay you, yousend me back parts. R ins and repeat!
Since this guy takes this apart he might as well do a full video on how to disassemble and put together. With video that far away, he is only showing like half the work.
Any changes to this procedure on the newer Bulldogs? I bought mine about a month ago and just got in some of your barrel supports. I'll probably put a little chamfer on the barrel transfer port while I'm in there, but not looking for big power increases yet. Bought the o rings for inside the breach end too, may or may not put them in right now. Eventually I'll probably put on the extended air tube and maybe the regulator, still thinking about those options.
I have a umerex gauntlet and one mod is to drill a small hole into the end of the shroud close to the receiver to give the air somewhere to go, could something like this help the bulldog
Great knowledge and mechanical skills you have…I am having a slow degassing leak on my Benjamin Bulldog after tightening back the depressurizing set screw. I just release air this one time wish I never did the depressurization. Do you have any advice on how to fix it?
turning clockwise will screw the adjuster in for more tension on the spring and normally gives more power. turning counter clockwise will decrease spring tension and normally gives less power.
"redneck blood" of a expert machinist, who make a good air rifle into one of the best. Is the same as it being annointed and blessed. By a saint.. As if a saint were a mechanist.
I started to watch this as I want to take mine on an aircraft, and they require that the pressure tube is not just empty, but removed. Is it possible to remove that tube without dismantling the entire weapon? I live in Panama, Central America and want to fly into the USA with it. And thank you for the time and effort you put into this. Very informative.
Hello, I have one or possibly two pellets jammed in my bulldog. The magazine is also stuck. I tried to tap it out with the plastic cleaner rod but, no luck. If not for the magazine being stuck, it would probably be easy to tap it out. I thought about carefully hacksawing the magazine in half, being careful not to saw anything but the magazine, and then prying the mag out? Any suggestions are appreciated.
You’re awesome dude thank you for the informative video. I’ve noticed my bulldog is losing air from 3000 PSI down to about 2200 psi in the amount of time of about a week without completely tearing it down what do you think would be the most common cause for the leak and an easy fix I tore down to get the barrel off and get out a jammed round But I didn’t feel comfortable taking apart the entire trigger assembly. I only took out the two Allen keys that lock in the barrel so I could get it out with a steel rod
I ordered one from Amazon Feb 7 2021 and then waited for the compressor to arrive today. I tried to add air, after 4 minutes the gauge did not move. I could here air coming out the front end area. I tried to get Amazon return for a replacement and found out that it was 7 days to late!! So now I have a gun I have never aired up and never shot but need to have rebuilt?! Thank you for the video!
Make sure that the gun is cocked before you try to fill it. With no air in the tank and not cocked the hammer pushes against the valve and let's it leak down the barrel.
I've been thinking about drilling my transfer ports. But I'm hesitant to do it myself. Do you offer a service? If so, can I mail you my reciever? Does my barrel have to go with it? Would max fpe be about 275, if kept unregulated?
Yes i can do it for you and yes i would have to have the barrel so that i can open up the port in the barrel to match. Every gun seems to be a little different but with the right ammo i don't think hitting 275 FPE would be to hard at all. If you wanted to really work on the valve you should be able to hit 300FPE. Or if you really want to get crazy then move over to Helium and you will have a 500 FPE gun.
Can that adjuster plug that you pointed be used to make some small power then changes to the gun? Or is it just for how easy or hard it is to cock the gun?
Just wanted to checkin and see if you are going to continue on with the whole series as planned. Would really like to see how to properly polish the trigger etc. before you move on IF POSSIBLE... Also got a quick question> Is it nessasary to degass the bulldog before cleaning the barrel OR could i just make sure guns not loaded, bolt open, and on safe to clean it with a rod and bore tip???...... Thanks in Advance... ~Jones~ [11/01/17] #PitbullAirguns #TheBenjaminBulldog #HPAirguns #KyAirGunners #ItsNotAFirearm
Really wish someone made a aluminum stock for these guns. I hate plastic. Part of the reason I sold my 3D printers…. It was a fun hobby for a second… I’m Just not big on plastic.
So Bulldog does not have any o rings around transfer port and just a tube is all?? Might removing the transfer port potentially leak the rifle?? if not, could you drill mine, too? thanks.
That is correct, the bulldog has no O-ring around the port. But removing the tube is not going to make any difference as the port did not affect the sealing either, it just floats around in there. Its just the pressure of the setscrew pushing the two machined surfaces together that creates a "seal" There is no seal around the pin on the valve either so that is also a potential leak. But we are working with such tight tolerances that i have not noticed any air loss in those areas.
I love the video. What disturbs me is the fact that the factory would send out a air gun that would be lose in any way. It makes me want to tear my gun down. Sad.
FPS is the wrong way to look at it. We normally rate the guns at FPE or Foot Pounds of Energy. The guns are rated at 200 FPE from the factory but are actually in the 175 FPE range. We can get to 300FPE very easily and have built guns that have gone over 600FPE.
Ok so I took mine mostly down to install depinger, put it all back together and now it won't cock.... any idea right off the bat what I could have done incorrectly? Thought I was being rather meticulous putting it back together but I'm not super familiar with these.
@@whatsmolly5741 I ended up taking mine to my local gun smith and it took him awhile to figure it out. Good luck! Maybe contacting Benjamin would be an option?
@@adamdobie455 this video actually saved me, the little poll the trigger is attached to, when he's reinstalling it he compresses the spring and I saw there was more thread visible than I have. Basically the trigger wobbled around while I put in the depinger and the poll was too short to hold the trigger closed. I just twisted it like 3 times and the trigger is close enough to the safety to hold shut. Kinda nuts that a literal millimeter is in the way of the gun firing when cooked.
Hey mat great job on the bulldog an all the info ,, have u ever thought about making parts an modding other guns?? It would probably really make ur business grow,, especially having a 3d printer you could make all kinds of stuff for different air gun like shot trays,pistol grips , fore grips even like some kind of stock brace that go,s under Texan tank ,, I would definitely buy one of them,,
Kevin, I've thought about it but i'm having so much fun with the Bulldog and am so busy with it i don't think i would have the time. I still have several new ideas for projects for the Bulldog that i need to work on too.
Lawrence, Unfortunately i haven't found any Air venturi rounds that work well. Try the Aeromagnum or High Arc Hunter bullets, Or just use the JSB pellet.
I think you are talking about the transfer port. You would have to remove the tube and then drill out the barrel and valve and you would get more power because it lets more air go through.
I really admire your skill! I really want to learn all about my new airgun. But, I need to take "baby steps". This is "meat" and I'm still on "milk". WoW! How do I ever remember where all those screws go back!? FYI... the demonic background noises are really distracting! I know you can't help that tho. number 9....number 9....number 9....number 9....number 9....number 9.... Thanks for the informative vid! ;-)
Sorry about the noises, that's just the 3d printers running. They make money so they can sound possesed if they want to. My advice is to video yourself taking your gun apart or takes lots and lots of pictures. But never be afraid to push your limits. Never stop learning!
Question for you : Here in France, there is a person who claims that for around 500 euros he can get the Bulldog shooting in the neighbourhood of 515 Joules (380 ft/pd) with an 82 grain bullit traveling at over 1100 ft/sec. What he doing sounds very similar to what you are doing. Does his claim seem reasonable? I'm looking for serious answers, folks. Cheers.
Hitting that power level is possible but not easy to do. And i would say impossible with an 82 grain pellet. You would have to single load some very heavy slugs to hit that level of energy. So i would say his claims are false unless he had a typo and meant 282gr .
Unfortunately the common barrel leak isn’t covered here. 28 shots and it’s worthless. There is no repair shop anywhere around me. What a waste. I’ll never by a crossman product again.

No problem.
I just got my bengiman bulldog and my dumb self lodged 4 .357 bullets into the chamber. How do I get those out. Please help!!!
Stupid question. Just put my first mag in the bulldog... pulled the cocking lever back and kept pressure on trigger essentially "decocking" it with a full mag in...now what?? Can the pellet be fired?? Or if I cock it again to fire will it double load?
If you cock it again it will double load. Best option is to open bolt and remove mag then close bolt and fire.
Other option is to hold the rotating section of the mag while you cock it and keep it from rotating. Then close the bolt on that open cylinder.
@@pitbull_airguns thank you!

It would be useful to have a listing of the sizes of tools needed for this. Maybe just add the list to your comments.
Roger that Edward, I'll work on that

No same procedure, a chamfer or radius on the edges is a great thing to do.
Love the videos! My degassing screw managed to fall out, but I found it laying next to a ball barring. That barring wasn't part of the valve, right?
No the little bearing is part of it. The bearing seats against the tapered bottom of the hole and is the seal.
I have a umerex gauntlet and one mod is to drill a small hole into the end of the shroud close to the receiver to give the air somewhere to go, could something like this help the bulldog

Pull the set screw all the way out and clean out the hole and the tiny little ball bearing. I bet that will fix it.
@@pitbull_airguns thx so much for the info/replying 👍🏻

Do you turn the hammer spring counter clockwise, or clockwise on the Bulldog for more power?
turning clockwise will screw the adjuster in for more tension on the spring and normally gives more power. turning counter clockwise will decrease spring tension and normally gives less power.

Hey brotha how much more accurate is the bulldog with the 4 barrel supports?
Most people have reported a 1/4MOA or better
For some reason the air wont go into my new Benjamin bulldog. It's out of the box brand new just like the pump and it just wont fill
Your one way valve in the foster fitting is stuck. You will have to take it apart and clean and lube it or replace it.
hey there. what air venturi rounds work the best in stock bulldog?
Lawrence, Unfortunately i haven't found any Air venturi rounds that work well. Try the Aeromagnum or High Arc Hunter bullets, Or just use the JSB pellet.
I hear movement in my barrel when I shake, is that normal
Absolutely not
Hello friend, very good videos.
I need a video how to install step by step of the valve Huma-valve for the bulldog .357 ....
Thank you. marcello
I'm working on that! It will be up as soon as i can get it done!
hammer how many grams
Why does removing that black plastic tube increase power?
I think you are talking about the transfer port. You would have to remove the tube and then drill out the barrel and valve and you would get more power because it lets more air go through.
Thank you
Can you working my gun I get the bulldog buy some thing wrong with my gun can you fixx
I've noticed your sucribed to me under your lake rat channel I was wondering if you've tried my trigger mod yet
I've watched it but haven't tried it. Looks like some great ideas. I will be doing a trigger video also.
