Why do people say that close bolt is more accurate

Perfect example of stupidity in motion.

'course this was after Dasbalddog editted out much of his demencia.

Autocockers are basically modified pump guns so what about pump guns?

Don't you love when people just sit there and argue you with you about something they obviously know nothing about. Then you're just supposed to believe them like it's gospel. Give me a break. Throw a 18" barrel on there and it'll go even farther.

Miscue is on the money here, this is 99% bleed over from real world weapon specs, where for single shot applications, closed bolt systems are more accurate.

Most open bolt firing mechanisms have enough weight when the bolt is thrown forward to move the muzzle of the barrel slightly, which translates into the bullet not hitting the target you were aiming at but hitting where the barrel was currently pointed at the time the round was fired.

When these guns are fired at full auto, it does not matter if they fire from open or closed bolt, as the affected recoil and reciprical action of the bolt will negate any said advantages of one system over the other.

Considering the paintball we are shooting is an imperfect sphere, is not spin stablized, is extremely light, and is fired at relatively low velocities, it will be greately affected by the surrounding air and environmental conditions, such to the point that it completely negates any said advantages of closed vs. open bolt systems, even in a single shot test. Add to this the fact that most people don't normally fire single shot in the first place with semi auto markers, and the argument then becomes completely moot.

Legend has it that, firing 100 balls at high bps will result in tighter shot patterns than slow bps (assuming that the reg keeps up). Reason being, the vacuum created by ball in front sucks in the ball behind it. Kinda like drafting in Nascar.

I have no data to back this up however... so it may not be the case.

Perfect spheres, as well as imperfect spheres, are inaccurate because the shape itself is not very aerodynamic. TK has high speed video that shows PBs zigzagging in the air, regardless of how round it is. Heavier paintballs, like Hellfire, supposedly fare better... but I'm waiting for some test results that verify this and show how much better they are.

This is how I remember it. Way back before the automag there were basically two different types of semi auto paintball guns. There were the closed bolts (one by Glenn Palmer and one by Bud Orr) and open bolt blow back guns. The blow back guns had the bolt attached to the hammer. When you fired the gun the hammer shoved the bolt forward driving the paintball into the barrel and then cracking open a valve to fire the gun. Considering the consistency (or lack thereof) of paintballs the force required to shove the paintball into the barrel would be different. Since the hammer was attached to the bolt the force with which the hammer struck the valve would also be different, causing inconsistent velocities. Also, the moving parts were heavier, causing more precoil/recoil (ie, the gun moved more). At least, that was the prevailing theory at the time.

mmmm, Hellfire with LVL 10... mmmm

I love it, I bought a case of Hellfire, and the guy looked at my RT like "what??" not a single break when I had that LVL 10 in my old RT.

This is a high quality photo of an Autococker. It has a transparent body, the red blobs are really bunches of WGP knomes, or cocker knomes, they are implanted into every autococker body, they hide in the sightrail and hop onto the bolt and ball to guide it. The green sphere... is a paintball.

Proof that closed bolt guns are more accurate and shoot farther.

ROFLMAO
i'm sold
guess it's time to drop the rt and pick up something with a closed bolt and gnomes

[No sKiLLz]

If you get a matrix, you're gnomes know kung fu, can jump over buildings, and dodge bullets.

[PsychoBaller]

There is no such thing as accuracy... for the MATRIX has you.... and there really isnt any paintball there to begin with..

for the same reason cockers shoot further than mags. It's just the way it is.

Wrong! Markers set to the same velocity shoot the same distance. (except for Flatlines)

It also doesn't matter which is more accurate because either way i'll bunker you at point blank with 10 year old house paint. *Laughing*

This is why: It is a known fact that closed bolt firearms are more accurate. This is because they have tighter tolerances.

However, people have misapplied firearm principles to paintball... and thus the myth that closed bolt markers are more accurate and such.

I agree. I believe the myth came out at a time before general access to the internet by lay-people and the involvement of people like Tom directly with the masses. Back in those days if you made a claim and could back it up with half-assed reasoning most people would buy it. Due to the fact that a paintball *gun* looks a lot like a real one people among other things believed:

1. Longer barrels shoot further/ more accurately

2. Rifling put spin on the ball and makes it more accurate.

3. Closed bolt (think bolt action sniper rifle) is more accurate then open bolt (think SMG or a semi auto M16)

To tell you truth many of these silly myths are still floating around today - like a classic I still hear frequently in cocker forums, "well we all know that open/closed bolt doesn't make a difference - but cockers shoot flatter." Or another, more modern classic, "low pressure is more accurate."
