Re: Sounds about right...
I'm with ya there. I have to have a shoulder "stock".

As far as open vs closed , 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.
I have friends too but...
You would have to eliminate the other factors to test for each catorgy.
For ball jump you would have to use the same air system, paint, barrel (check with dial indicator), and clamp down the guns so the precoil doesn't count. Changing up bolts would help too. Like I said... It would take some connections and money.
The paint would have to be two coloured and place in so you may see if there is any spin. It would have to be indoors and with a lot of paint.
Tom want to give it a try?
Why handguns are accurate...
The reason that handgun jump has little effect on handgun accuracy is simple: the bullet is traveling so fast that it leaves the barrel before the barrel jumps due to recoil.
As far as open bolt versus closed bolt, there is only ONE reason the cocker is a closed bolt gun: it is based off the Sniper pump gun. So, instead of being a semi-auto in the traditional sense, it is in fact a pneumatically pumping pump gun. Also, any movement caused by the mag bolt loading the ball into the chamber is negated by the barrel. As far as accuracy goes, (barring spin), the barrel is the great equalizer of paintguns. Once into the breech(sp?), then it's fair game as far as the paintball is concerned.
Well, I'm tired. Good night.
