standard and non-standard magazines is not cost effective and,
therefore, is discouraged. The element that greatly influence
the magazine classification (standard or non-standard) is the
headwall and its door. Since the headwall and door cost is a
small portion of the overall cost of the magazine, a greater
benefit is realized from the increased storage capacity in
standard magazines.
