They did it the same way other contemporary gunmakers of the time did it: return to the barrel shop, chock the barrels into whatever jig was used to align, center, bore and lap the individual choke cones and run of constriction to achieve pattern density, alignment, concentricity and distribution according to the customer's desired specifications. The Order Books are full of citations for guns returned with the notations, "open chokes", "make shoot straight", "pattern RB X%, LB Y%", "make shoot 6" high at 35 yards", and so forth an so on. No mystery or alchemy here (unlike things like case coloring and nitre bluing formulas); this was all mechanics and careful attention to detail.
