there is a great writeup on GTA by TKerrigan for porting a Bulldog and i'm trying to find a stock one right now to use to make a video.

new .357 bulldog ammo test
- Thread starter TheLakeRat
- Start date
Once you get the sides of the gun you can see very clearly where you can add material and where you can't. There are supports inside the plastic that touch the actual gun and you cannot put material in those areas.
The biggest sound deadening think to do besides the LDC is a depinger of some sort, or a regulator. But the sound deadening material does help.
I personally would not recommend a novice drill the port with a hand drill. A drill press or mill where the receiver and barrel can be squared up is best. But without drilling that transfer port it's not going to hit that 200 ft/lbs of energy. Or rather I don't think you will.
There is definitely an advantage to adjusting the hammer spring to tune your rifle but that's with just about every PCP on the market. To do that correctly you need to have a chronometer. The purpose of adjusting it is not only more power but to adjust the power for the bullet your using and try get the correct bell curve of you aren't running a regulator.
I will let you folks know when I've got things ready to sell. And brightboi, when i do you can send me your rifle and whatever ammo you want to use and I'll tune it for you.

Lake Rat,
Yeah... I'm a bit hesitant to start drilling away at it.
I'll see where I can add the sound dampening material and will play with the hammer spring, valve spring, etc... to see what I can get. I do have a chronograph.
When you get the LDC's completed (and whatever else) I'll take you up on at least the LDC and would be very pleased to have you tune my Bulldog up...
Just let me know.

Yes, I got a 3d printed prototype done this weekend and just have to change a few small things and then print out another to make sure it all fits and installs correctly. I did fire my prototype with no baffle strikes so thats a great start.
As soon as i get that done then i can start printing out usable models to sell.

Lake Rat,
Just checking in to see where you're at on the LDC.
What do you think you'll price them at?

Things are looking good. Started a you tube site under pitbull airguns
This is stock
This is with the short version.

I read your adjustments to your gun, I think you have a LDC on her not sure, But its evident that you have got the power up and the sound and the ping down,
Is it back yard friendly yet? LOL. when you say Now i’m running a longer tube at 4500psi with a regulator, are you talking about the barrel, ?

I believe he is referring to the air tube, he changed out the stock bulldog air tube for the longer one found on the pioneer air bow if I'm not mistaking.

X27 is correct. I meant the air reservoir tube. And I do have a suppressor on it.
I will be selling those soon and then I will start selling the biggest reservoirs and some other Bulldog parts soon.
As for backyard friendly? you tell me.
This is stock.
This is my latest design.

Lake Rat,
Looks like that is exactly what I need.
Do you have any kind of ETA and cost yet. Not that I'm chomping at the bit or anything... HA!
I NEED ONE!
Good job... Please let me know.

Al Hartford of Aero-magnum bullets does a great job with his bullets. The only thing I could previously get to shoot accurately out of my Bulldog were bullets I cast from an old 1950s Ideal .357 pistol mold that my neighbor gave me (sub inch groups at 50 yards). That let me know the potential of the Bulldog because the Noslers and JSBs weren't that accurate. I have since switched to Al''s Bullets for the convenience and hollow point when deer hunting.
Interesting posts on silencing a Bulldog. I have found when deer hunting even on smaller tracts of land that other deer hunters usually do not know when you have shot even a standard Bulldog. Don't know if it is the unusual sound signature of a Bulldog in that type of setting or what.
One further note on Aero-magnum bullets, Al is currently developing a .457 for the Texan. I'll post something as soon as it comes to fruition.
