Test protocol includes three distinct, but overlapping, phases. Before a single shell or cartridge is loaded, each firearm is inspected, measured, weighed, cleaned if necessary, and in the case of the rifles, scoped up. This time-consuming process is what we use to build the data sheets provided to each tester, which list all the vital statistics about the firearm. We're so picky during this process that we even assign number grades to reflect the quality of the machining on the bore and rifling, for instance. Suffice it to say there's no nook or cranny on these rifles and shotguns, all of which are field-stripped and disassembled, that isn't inspected.
