I have about 12 or 13 turrets and never had something like this occur?? There is a little spring loaded roller bearing in the inside of the main press where the turrets pop in, does that roll and can you push it in and out??. Put some oil on it. Without the rod or any dies the turret should just turn easily by hand.

Other than that I can not understand it without seeing it. Sound like the turret is out of spec. But they sent you other ones so something is very odd. As you said call them while you are at the press. Be sure to ask for a Technician (in the shop area)
