While most semi players may need more shots, the ones who try to aim (like most pumpers) make it happen.

Also, ALL mechanical pumps have weight transfer.

Most mechanical pumps have *one way* weight transfer. Pump markers with a pneumatic trigger don't(Cocker pumps).

What?

There are no pneumatics on my sniper...

The hammer still has to move no matter what. Therefore weight transfer...

With far fewer moving parts the pump won't have the vibration or kick. On a typical sear tripper the sear has to be released and the hammer strike a pin prior to the round receiving an air charge. This is weight transfer. After the pin is struck the hammer has to slam back and lock into the sear. The bolt itself will be moving at an extremely high rate of speed pushing the round causing even more of a disturbance. Depending on the pump you don't have any of that. Just a single charge release. No hammer running back and forth, no bolt movement. A pump is much more predictable than a semi.

ONLY with an MQ valve would you get these results you speak of

slower rate of fire=more time aiming. more time aiming = more consistancy with your shots. personally i think everyone should own and take time using a pump it teaches you how to make paint last especially if your using first strike rounds

I will have to say that i am on tempted's side with the fact that if i had five shots, i would use a pump(cocker or phantom design) instead of any other semi marker. But as much as i would like to think that closed bolt is more accurate( in the fact that there is less vibration), i know that this is not true because i know that when i shoot my Sheridan PGP that hammer comes forward, and i can feel the vibrations a lot.

I know that people say it's proven that closed bolt is not more accurate than open bolt, but I just don't understand how it's possible. We're talking about a ball sitting in a barrel at rest, nice and snug waiting for a solid blast of air (closed). Versus a ball being pushed forward and blasted with air.

The ball has to accelerate through the barrel regardless of the bolt operation. If the paint is properly matched to the barrel, there is no room for it to go squirrely before it leaves the barrel...well after the bolt has finished having any kind of contact with the ball...

basically, it is air that pushes the ball. It does not matter that much where the air starts.

no but the motion of the bolt pushing the ball forward before it is shot is the only difference. some movement vs no movement is obivous in terms of stability

it has to do with the number of moving parts in the gun and weight of the the total number of moving parts. semi auto will have more moving parts and the parts move not just once at the time of fireing like in a pump. plus the bolt and hammer don't move independantly from eachother like in a pump. there for a lil over twice the kick. which will effect accuracy. (granted some guns are lighter than others but were talking in a controlled environment here. the receivers being identicle weight just the internals being different)

I guess when you think about it, a marker's accuracy is determined purely by 3 things.

The consistency at which air is delivered to a ball
The consistency of the paintball's size & shape
The quality of the barrel

This is assuming that Closed & Open bolt, given they have these same consistencies and qualities, will deliver the exact same level of accuracy.

The moving hammer doesn't kick the gun, the motion is linear. This "kick" is from the expulsion if air.

But, even if accuracy is different (favoring either side), we are talking about less than an inch. Long distance shots will have greater influences such as fps consistency, ball geometry, and air factors.

Point is, no matter who wins the argument, it doesn't really matter.

Agreed with wowzerz!

The Biggest single thing that affects accuracy more than anything else is the meat sack pulling the trigger. Doesnt mater if the gun is the most consistant thing in the world if the shooter cant aim.
