[QUOTE="BryanLitz, post: 345784, member: 7848"] There are lots of 'generalities' to make about the two types of rifling methods, but few hard facts. Here are some generalizations. In general: 1) You're more likely to get an accurate twist rate with cut riflings than button riflings. 2) Button riflings are easier on bullet jackets (less likely to produce bullet failure) than cut riflings. This may be changing with the advent of contoured (5R) cut riflings. 3) I think cut riflings are less likely to induce stress into the barrel steel. I'm not an expert on this so please correct me if any of my generalizations are inaccurate. -Bryan [/QUOTE]
