The muzzle brake works way better than I thought

Tested it with and without the brake, same ammo, same setup -Biiiiiig difference

Just for the muzzle brake?
I think I joined for the gun before....
How do I even join? What do I have to do? Because I made something else also 😄
GunnitRust@reddit
Yes muzzle brake

You give me worrisome thoughts. A couple mo the ago a buddy of mine sent me an 8” or so cutoff section of a Lothar-Walter 50BMG barrel. Both ends are threaded, no chamber yet, outside is full thickness to do with as I please. Figured it had no use. Now? Dangerous thoughts abound. Ha!
sanfte8@reddit (OP)
Go ahead, do it!
Outrageous-Till8252@reddit
Middle piece with threaded ends. I really should go out and truly measure the length so I know what I have https://x.com/notaguntuber/status/1903184915534852602

I wish I had a rest piece like that... buying the barrel from Lothar Walther was the second most expensive thing about that build (most expensive was the Colt 1911)
Well, I had a rest piece but it wasn't big enough for a chamber (probably would have been enough but I wanted it to be extra safe)
Luckily I already had a chamber reamer because these are damn expensive also

Odd question, can I get the specs on that testing rig? Like weight and dimensions?
sanfte8@reddit (OP)
I can take some measurements later... wanna calculate the recoil?
afleticwork@reddit
I wanna built my own for testing, have you chronographed this gun?
sanfte8@reddit (OP)
I tried to but the chronograph was probably to close and didn't anything... to go away further I first want to add some sights, so I can properly aim it through the chrono
afleticwork@reddit
Fair enough, have fun bud this gun is damn cool i want one lol

If you angle the baffles on the brake would it generate negative recoil as in pull the gun forward ?
sanfte8@reddit (OP)
In theory yes but it would never pull the gun as much forward as its pushing it back... like it would never equal out the bullet and explosion going forward completely...
Also I have a .308 rifle with backwards baffles in the muzzle brake and its not only unpleasant to shoot for the shooter next to you but also for yourself. It's like an explosion to your face with every shot and you can see my hair flying back in the muzzle blast...

Your hair getting blown around would make for a fun fake "Because You’re Worth It L’Oréal Paris" add

You could create a giant gas tube connected to a blast chamber to reroute the blast behind you like a recoilless rifle.

An exhaust on a rifle 🤘😂
phloppy_phellatio@reddit
For every action there is an equal and opposite reaction. That means the energy of the projectile (1/2 times mass m times velocity squared) is also getting applied to the firearm in terms of recoil.
The projectile is not the only thing getting expelled though, hot gasses are also getting expelled and increase the recoil so that it is even more energy. Muzzle devices redirect, disrupt or slow those gasses to reduce recoil generated.
It is impossible to redirect enough energy in gas rearwards to equal the energy of the projectile and non-redirected gasses.
Another way to think of it. Fire a blank without a muzzle device. The amount of recoil you feel from that is essentially the maximum amount of recoil mitigation you can generate with a 100% efficient muzzle device.

Great video. What caliber is it?
sanfte8@reddit (OP)
50bmg
K9turrent@reddit
I love that you actually did some measurements and quantified your results!
The only difference between science and messing around is if your write shit down
sanfte8@reddit (OP)
"Yeah, Science bitch!" 😆
Green__lightning@reddit
Why the sliding setup, rather than a ballistic pendulum?
sanfte8@reddit (OP)
Easier for me to build I guess... didn't even think about a pendulum to be honest
Green__lightning@reddit
The ballistic pendulum is a longstanding way to measure the energy of projectiles and the recoil of guns, as this was how they figured out the energy of projectiles before more modern methods. It's easy to know the mass of the pendulum, and how far up it swings, and you can calculate the energy from this.
AyeBraine@reddit
Will it allow measuring the upwards flip? I thought this setup was supposed to simulate a bit of that, with the slightly compressing (?) arm and freely pivoting "shoulder".
Green__lightning@reddit
No, just the linear impulse, you could calculate the flip from that, but that's more about ergonomics and kinematics.
AltGunAccount@reddit
Gotta hand fire it again. For science.
I won’t claim to know much about firing a 50 BMG pistol but based on your last vid maybe drop one foot back and lean into it a bit harder.
Consider wearing boxing/lifting gloves, something with a heavy wrist strap to help keep it straight.
I have faith you can get this monstrosity made into something actually useable by humans.
Doing God’s work OP.
