Just that hammer forging and button rifling is not an either or proposition. Most barrels are hammer forged and button rifled including most of the highest end custom barrels currently in production. The idea that the button rifling technique is inferior, is way out there my friend! Here are some of the inferior button endrifled manufacturers. MRC, Broughton, Lilja, Hart, Shilen, Douglas, Schneider, Pac-Nor. Hey wait a minute arent they the names you always hear associated with winning long range championships?
