ATRS 50 Brake

Rman said:
Dude, you're hopeless. High school was obviously a lot longer ago for me, than it was for you. I have never mentioned a ATRS brake once in my "conversations" with you. I don't own one, and probably never will (sorry Rick). If you actually read anything I wrote, and responded to some of my questions, you may have learned something. You obviously don't want that to happen. I have provided you with many facts that you have not bothered to confirm. Fact: there are several world records held by clam/gill brakes, including the one(s) mentioned above. Fact: Shooting a 360 degree ported brake prone sucks. Fact: Gasses exit the barrel before the bullet does. Fact: There is information all over the internet about what type of brake is more effective than another type. Fact: You are too lazy to look for this information and find out for yourself. And last but not least: Fact: You do not have a clue about what you are talking about, and that you think you can build a brake is the biggest joke to come along in a while, since you don't even understand how they work. It is bad enough that I am wasting my time with you. Not a total waste, as there is an entertainment factor to it, but that you think someone else should do your research for you is beyond laughable.

gasses exit the barrel before the bullet does??? I can admit that i did think that the gases were behind the bullet and that the bullet would exit the barrel before the gases do???

I could have been wrong but i though that when the powder ignites it forces the bullet out of the case neck through the throat and into the rifling and creates a seal between the bullet and the barrel. Keeping the pressurized gasses that are trying to escape through the easiest path (down the barrel and out the muzzle) behind the bullet so that the expanding gasses behind the bullet would propel the bullet down the barrel and then once the bullet is clear of the muzzle the gasses can escape.

If the gasses exit the barrel before the bullet does then the gasses would be in front of the bullet. If the gasses are in front of the bullet what is behind the bullet to force it out the barrel??

I though this is why the a 50BMG bullet is actually 0.51" not 0.50" so that the bullet would seal tightly into the rifling keeping the gasses behind the bullet not in front of them.

Once my 360 degree ported brake is finished i can send you a picture if you would like

Can anyone explain to me "FACT THE GASSES EXIT THE BARREL BEFORE THE BULLET DOES"
I would be glad to hear a civilized explanation and i would like to know what makes the bullet accelerate if the expanding gasses exit the barrel first and there for are in front and not behind the bullet??

thanks

Clearly you aren't capable of thinking in terms of anything but absolutes. Gases bleed past the imperfect barrel-bullet seal, and a small portion exits prior to the bullet. The rest exit afterwards, and have little or nothing to do with the bullet's accuracy. The pre-exit gases are like a VERY strong wind next to your bullet and need to be dispersed as evenly as possible - this happens with a gill brake and a radial brake, and the key here isn't design but rather symmetry. The post-exit gases are why muzzle brakes tame recoil; directed properly, they can pull the rifle forward and reduce muzzle jump.

In addition to the bleed-by gases, there is also a column of air in the barrel ahead of the bullet. This gets pushed out as well - so, even if the barrel-bullet seal is flawless, there's still this rapidly-compressed gas to deal with. By nature, this gas is in front of the projectile.

So, not only are you incorrect about gases not exiting in front of the projectile, you're actually wrong about it on TWO counts.

Look at this video - just prior to the projectile exiting the barrel, you can see a compression ring and gas venting from in front of the projectile. I hope this makes things a little clearer.

Yes, it's a tank projectile - but the principle here is the same, and the ultra-high-speed video is flawless.

Now, go apologize to Rman. Oh, wait - you can't because you've been banned in the time it took me to write this.

Oh happy day!

I see proverbial Darwinism has struck again. :rolleyes:

Over the years I've had a few hundred employees and have never fired a single one.

However quite a few do fire themselves. ;)
