Becuase of this, some balls only get halfway into the chamber and then BAM, the bolt splits the ball clean in half. i suggest getting a electric hopper such as and egg.

Once I installed my E-Bolt I did test after test using the gravity feed hopper to see it it could keep up with the 13 bps rate I could induce with my 98C. Paint tended to jam in the upper neck of the hopper stopping flow  every 20 to 30  shots causing me to have to shake the marker to get paint rolling again. But, in no case, while the hopper fed, did it feed slowly enough to cause a ball to be chopped by the bolt. Either the paint flowed or it did not. there was no "slow feed" that caught a ball only half way into the chamber.

I had three different brands of gravity feed hoppers and all worked as well. I saw no indication that it was possible to out-shoot the gravity feed at E-Grip or E-Bolt semi-auto rates of fire as high as 13 bps.
