Tonight me and my brother went to check out reball for the first time. His brand new automag ule custom rt with ult trigger would not shoot reballs consistently. The gun would chuff and ball would roll out or would chuff and not fire. My tac one ule custom would do the same but then I had to stick my finger in feed neck and push the bolt back about an 1/8" to reset bolt, other wise it would just stop even attempting to fire. We had our guns down to about the 230~240fps range. Guns also fire paint great just not reballs. One thing I did try was swapping out my gold spring for red but the it would not shoot at all. If I have too I'll put a lvl 7 bolt set up in it for reball but don't really want to deal with all that. Any help would be appreciated, thanks.
