In reply to: griffin-owner 's message, "ball chopping" on 17:08:38 05/18/03 Sun

There are two different types of breaks: BREAK and CHOP. A break occurs mostly inside the barrel. Usually this is identified when you get paint soup draining out the end of the barrel. A chop occurs when the bolt slices a ball. Usually this is identified by paint flying up inside your powerfeed and elbow.

BREAK

- Velocity too high. Check it at a chronograph (and nowhere but a calibrated chronograph).
- Bolt face rough.
- Old (older than two months) paint.
- Bad (swollen, dimpled, cheap, damp) paint.
- Shooting large (field) paint in a medium or small barrel.
- Scratches or dried paint inside your barrel.

CHOP

- Ball detente out of adjustment. Either only 90% of the ball is in the breech prior to firing, or one and 10% of the next ball are there. Either way the bolt is slicing one of them.
- Bolt face rough.
- Powerfeed not turned correctly/enough. Powerfeed not smooth.
- Shooting faster than your hopper can feed.
- Inside of elbow not smooth, slowing down the feed rate into the gun.

See if any of these help.

Are you using a motorized hopper? Usually a good hopper will keep a ball in the chamber at all times (assuming you're not firing upside down or sideways).
