.177 FX sideshot magazine

I received a new mag last week and I’m having issues with the pellets either jamming up or cocking sideways between shots . Anyone else having this problem . I have the FX version and not the original version . The .22 cal mag doesn’t have this issue they cycle fine . 

It looks like there is too much clearance between the wheel and housing . I’m going to try a wrap or two of tape on the inside of the housing to take up some of the slack .
