What matters is what's on the label.
Well yes and no.... When you have say 40-50 boxes and from the front all look the same (say green) and stored in the same place... Not good.... It is handy to just glance at the color and know this box is .45 Colt... rather than start pulling boxes until you run into one that is labeled .45 Colt on top. Labeling is important for the load documentation, but color is helpful (for me) to pull the right box to begin with
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
