[QUOTE="shortgrass, post: 378529, member: 24284"] A pic is worth a thousand words, here's Shilens' web with a good pic. [URL="http://www.shilen.com/ratchetRifle.html"]www.shilen.com/ratchetRifle.html[/URL] Button rifling is a manufacturing method. the button is either pushed or pull thru a reamed and polished hole to form the lands and grooves. "Cut" rifling is another manufacturing method where each groove is cut, individually, with a cutter. Broached rifling is another manufacturing method that uses a cutter called a broach which is pushed or pull thu the reamed and polished bore and cuts all the grooves at the same time. Hammer forging is another method, mostly used in Europe (someone correct me if I'am wrong) and it involves the barrel being hot forged around a mandral that has reverse rifling on it. the mandral is removed from the inside of the barrel and it leaves the rifling 'imprint' in the bore. Conventional rifling and canted or ratchet rifling, I think, could be best described as engineering principals. Check the link as my explanation is, no doubt, clear as mud!:D [/QUOTE]
