Are your bullets going into the dropper at all? I had a couple of problems with .224 bullets. first the bullets were getting hung up before going into the dropper, I had to reposition the spring slide and shorten it to make them drop in the dropper. second I had the bullets getting hung up in the dropper which was caused by the switch in the dropper. CED sent me a new style switch and it took care of the problem. Hope this helps.
