Maybe the problem is that you are trying to load flat base bullets instead of boattails. Boattails should slip right into the case mouth and pressed WITH FORCE into place. Flat base bullets require that the case mouth be slightly expanded so that they can slip in and then you still need to use force from you press to seat them to the proper depth. Make sure you are following the instructions on your dies EXACTLY. IE. If it says screw in 3 turns then do that.
