6.5mm Bullet Connectors Don't Fit

[Supreme Reign]

I bought the CC 6.5mm Bullet Connectors to a make a lead from my 1515 2200kv to my ESC with 4mm inputs. The males cannot enter the females no matter how hard I push. The male connectors on the motor cannot fit into the female connectors either. Pinching the motor's connectors didn't help, either. I'm 255LBS so I'm no scrawny dude. All the male connectors are too big for the female connectors. I have lots of CC motors and ESC's with 4mm bullet connectors, and I've never encountered this problem. Is this normal with CC 6.5mm hardware??
