My Custom 98 is Chopping Balls

I have a Custom 98, with a Tippmann Flatline, Cyclone feeder and new rings. Why does the gun continue to break balls??
I use Marbalizer paintballs, good paint,so upgrading balls is not the answer. It has happened from day one just about.

The ball is chopped in the chamber not broken in the barrell. I have adjusted the velocity screw hundreds of times.

Does anyone have any suggestions???

I bought the cyclone feeder to hopefully correct the problem. It has not changed anything.

I followed the instructions to a T.
Again this problem existed before the FlatLine also. I guess I forgot to mention it.

Would something be catching in the chamber, spur, I do notice the power tube hitting & srapping the extention for the Flat Line. Maybe polishing the surface would help?

This is the exact same problem I am having, I see you are from Canada. I am from New York. So heres how it goes, in the summer my cyclone feed was amazing no complaints. Now suddenly the gun chops paint non-stop. Another simularity is that I too am using top class paintballs, Marbalizers. The barrel is new no scratches, the cyclone is installed just as described in the manual. The connection to the power tube is not stripped so everything installed fine. I came down with one conclucion. It is the temperature. Now that it is winter time the Co2 freezes up the chamber and the powertube. I noticed that the tube connection where the screw is freezes up and looks as though it had been snowed on. The ice inside the tube will cause blowback gas to fail to go through giving the cyclone not enough presure to spin the blades. The chopping paint comes from the front gas presure to shoot opposite direction into the bladed hopper and crushing the paintballs. My only alternative is to switch back to gravity feed until the cold weather is gone, which is summer time. Hypothesis not proven, but it is the only alternative and explination for the breaks.

what is a ball detent? Are you talking about the Ball latch, the thing that holds the paintball in place??

Some of the Flatline barrels have a relatively sharp edge at the transition from the receiver into the barrel. Two of my Flatlines (I had three at one time) had this sharp edge. I used a chamfering tool to break the sharp edge (smooth to a 45 degree bevel...ever so slightly)  and broken balls went away.

Bring it to a pro shop

Well, my ball detent or ball latch is in the right way. I do not ball when it is cold and even with multiple shots its understood that the barrel gets cold. It was doing this when the barrel was warm also.
No Pro Shops here either, just me.
I still broke balls even without the flatline, I had a Progressive barrel also, it didn't make a difference.

Does anyone know if the "parts" kit from Tippmann has all the parts I need to fix everything for guts inside (ie new power tube, rings, detent, ect.)Maybe an overhaul would be appropriate.

Does it chop during slow single firing?  When you let a ball go all the way in to the chamber and then take a single shot and wait for another ball to feed in completely and then take another shot does it still break paint?  If it breaks paint on these single shots then it's a problem IN then gun.  If it fires fine in this way then it's most likely a problem FEEDING paint in to the gun (feeder / breech / etc).

 

Take off the barrel completely.  Tip the gun back so the ball doesn't fall out.  Shoot the gun with no barrel.  Break or no break?
