Optimum bullet performance, cast or jacketed, is impossible if the gun’s guiding surfaces aren’t capable of holding and starting the bullet in perfect balance. Rough internal finishes, oversized throats and/or bores, rapid changes in twist rate, and constricted or lumpy bore diameters cause inferior accuracy and excessive fowling. These constrictions and diameter changes are almost always present where revolver barrels thread into the frame and on all guns at any point along the barrel that was machined, stamped, welded or contoured [on the exterior surface]. To this end, Veral has created two unique types of slugs for controlling the lapping process and measuring the exact diameter of your particular rifle or handgun.
