Metric vs Imperial

Because of shifts in naming gatherings, and the whims of the cartridge makers, shot widths can differ substantially from the width suggested by the name. Case in point, there is a departure of the same amount as 0.045 creeps (1.15 mm) between the most diminutive and most impressive of the some cartridges designated as ‘.38 bore’. Then again it might be noted that .38 crawls is more than 9 1/2 mm.
