Default Uniformity leads to repeatability

Just to clarify - by "square neck" do you mean that the mouth of the cases are not perpendicular to the case body or that all edges of the mouth are not even/parallel with each other?

You want uniformity, which leads to consistent repeatability. I would recommend that you trim the case mouth so there is uniform contact with bullet as it exits case. If you aren't convinced that its worth the effort then load up 15 rounds (3 sets of 5 shots) without trimming and 15 shots with cases trimmed square to same length. Shoot them at range and Compare the results.
