I recently bought and started using my first Redding Full Length Bushing die. My loaded round neck diameter is running between 0.3355 to 0.336" and I bought the 0.334" bushing. The force required to seat a bullet is more than I am used to. Is too much neck tension problematic for accuracy? I do not have the expander ball installed because I thought with the bushing it would not be necessary and could negatively impact neck concentricity. Should I put the expander ball back in place or should I try a 0.335" bushing or not worry about it? Thanks, Rufous.
