Not sure when it is getting sticky but loosening the parts will work. This meaning the knobs on top and the caps on top of the injector tubes. If it is happeing when it is full then I have to go with it not being up to operating temp. You need to be smooth with your motions and try and not hesitate when filling and shooting. It will get much better as you use it more and more. If you still have problems pm me your # and I will go over it with you as you work with it. The unit is great but to make it affordable it is aluminium,not the best product as it will get sticky(gall) when it is bound. I have a set of injectors that have steel shafts and linear bearings. Real smooth but the price is real high. I still have the first ones ever built and they are still going strong. Kevin told me that at ICAST this year. Good Luck and be SMOOTH Frank
