# FAQ & Trouble Shooting

## Common Questions

**Q: What wheels are recommended?**

A: The 4” WCP Solid Roller Wheels are the recommended wheel to use.

**Q: What size game objects does the shooter support?**

A: This GreyT Shooter was designed with a 9.5” game object in mind. Other sizes may be used, but the performance may vary as smaller or larger game objects were not taken into consideration.

## Common Issue

**Issue: Not shooting far enough.**

Possible Solutions:

1. The RPM may not be high enough. Try increasing the RPM to gain distance.
2. The compression on the game object is not enough. Try increasing the compression by moving the standoffs that support the plastic hood backing forward to the next set of holes.
3. If both of the previous suggestions do not work, then you may have to either gear the shooter faster, or add the top roller.
