Proof that an autococker shoots further?

The thing is they CAN'T accelerate outside of the barrel. The pressure behind the ball equalizes within an inch of leaving the barrel if it is an unported barrel (which most barrels are not). Since there is no longer any pressure behind the ball (especially at the distance that the gun is checked at the chrono), there is nothing accelerating it, so the only force acting on it is the resistance of the air, which is the same.

well i'm gonna go to sleep, it's 12:07 PM here on the west coast and I can barely keep my eyes open. I'll get back on tommorrow and argue some more. good night...

I've got an idea!

Let this guy win!

Then everyone with cockers will either have to switch to a new Tournament legal marker, or chrono in lower than everyone else to stay in range after the magical acceleration!

Hey, thats a great idea. Since cockers have more range, then its not fair for everyone else, so now they have to chrono in at 15 fps lower than everyone else. I can live with this.

Someone correct me if I'm wrong (it's late, I can't think this through as thoroughly as I should), but doesn't the ball's velocity increase throughout the length of the unported section of the barrel? I'm under the impression that the rate of accelation may change, but that it remains positive up until the ball hits porting or the open air.

Ok...for starters, reduced deceleration DOES NOT count as acceleration...extremely poor way of putting it...if you'll stop saying that the ball accelerates after it leaves the barrel maybe I'll stop making fun of you...

I hope you're joking about the left over air...

Stop and think about how these guns fire...

Autococker:

Hammer goes forward, poppet valve goes pop, releases air into the chamber/bolt and closes, air expands, cuasing ball to go forward.

All in all pretty efficient, and I assume in the cases you are reffering to low pressure is being used, which means that the point at which the air has expanded as much as it can and still provide thrust arrives quickly.


Automag:

400 psi dumped through the bolt behind the ball. Higher initial pressure means that the air has a lot of expanding to do. Meaning that more volume will likely be filled before the expansion of the air ceases to provide thrust. The efficiency of a mag also tends to be lower, indicating wasted gas.

So what we have with the mag is a gun that releases air at a higher initial pressure, and wastes more gas. Which means that if you stop and think about it, if any gun is likely to be spitting out enough gas, at a high enough pressure to provide ANY kind of force on the ball anywhere near the end of a barrel, let allone just out side the barrel that gun would be a mag.

My point is that your argument doesn't even make sense when "bench racing" the guns...all you have to do is stop and think about it to see that an LP cocker of all guns wouldn't be able to accelerate a ball after its gone too far down the barrel.

Mags spit out alot of gas, and at high pressures, meaning that they, of all guns are more likely to accelerate a ball towards the end of a barrel.

To which you will probably make another stupid reply improperly using the word ejaculate...I don't know why I'm even bothering....


**After reading this I realize it could be taken the wrong way...my point is that strongboy's theory is total bunk, doesn't work and is especially stupid on cockers. I didn't mean to make it sound like his hype would apply to the way a mag shoots.

Yep, the rate of acceleration decreases as the pressure behind it drops, and the force behind the ball decreases, but the acceleration is always positive as long as there is more pressure behind the ball then there is in front of it. Once the ball reaches either a ported section or the end of the barrel, the pressure behind the ball equalizes, and the ball then declerates.

Ok, past 3 in the morning, if anyone thinks the gun makes a difference, i don't care anymore, you can be stupid all you want.

my bad. but the point still stands. a ball, once it leaves the barrel, MAY still accelerate some. I'm saying for a fraction of a second the autococker might still be accelertating while the automag would have already begun decelerating.

WRONG!!!!!!!!

The correct thing to say is "for a fraction of a second the automag might still be accelertating while the autococker would have already begun decelerating."

WOWZERS!!!! SEE WHEN I SPIN IT AROUND THE STATEMENT IS EQUALLY LOGICAL (zero logic) but it says a different thing? YONKERS!

I like how a few pages back he says that the flatline barrel's backspin on paintballs causes them to decelerate slower during horizontal flight, and this is why it provides more distance. :)

Learn some physics, buddy. It's called the Magnus Effect, and involves high and low pressure areas around the paintball that provide lift, but not enough to counteract the force of gravity.

If you shot two paintballs, one out of a flatline and one out of a normal barrel, same speed, at 50 feet both would have the same horizontal velocity, but the flatline ball would be higher from the ground.

Try it in a vacuum and the flatline would make no difference in the flight path of a paintball.

OK, I'm closing this, because I can see the flames closing in on us.
