[QUOTE="Mikecr, post: 912919, member: 1521"] There is another affect of contouring barrels; bore dimension changes. With button rifled barrels, you need the lapping done -after contouring. This because bores grow with contouring them. Little to no affect to cut rifled barrels -once up to stable shooting temps. Hammer forged barrel bores actually shrink with contouring. This can work to provide choking toward the muzzle(taper bore), which can be beneficial. [/QUOTE]
