Low velocity Hiss problems any ideas?

[robbieisurfriend]

Alright guys i took my pump mag to the indoor reball pump open play today (200fps limit!!!!!) and i had some small problems with it. I was told that a mag wouldnt even seal up alter shooting at 200fps but most of the time it worked beautifully. It seemed to shoot fine over the chronograph but occasianally it wouldnt shoot at all. It would get a low shot, then a lower, then one would BARELY leave the barrel and finally it would hiss when the trigger was pulled ofr another 6 or 8 shots without actually firing then it went back to firing perfect for another 15 or 20 shots. If it didnt shoot so well i would just give up and say its not meant for it but it showed ALOT of potential. I am going to try to take everything down and relube it to see if that makes it go away but any suggestions would be great. I was using a verical 4oz in the asa and of course not shooting fast enough to get liquid in the gun. thanks

You shouldn't have any problems with shooting at 200fps. I've done that with my mag before. If it can't get to that low velocity, cut a piece off the bolt spring.

i am guessing my problem was the pumping and tilting the gun with a vertical co2 tank was freezing the valve up. I am not really sure how to fix this though.

im kind of missing why there is a 200 limit, reballs are suppoed to be used at normal velecioties and indoor fields usually only drop to 250.

can the balls even go very far at 200?

its not my rule and yes the field is literly small enough that at 200fps you can hit the other side of the field with just a slight angle. This tiny field and about 30people bunkering eachother made them lower velocity i presume.
