[QUOTE="jmden, post: 576907, member: 1742"] One thing Kirby will recommend for these hi-perf chamberings is a barrel with land width that comprises in the 19-22% bearing surface range or thereabouts. There is concern of the too wide of lands causing jacket/core separation. He's experimentally tested this with certain bullets that had the issue in he-perf chamberings and the fix was narrower lands. Have recently had this discussion with him. His list of barrel makers he prefers to work with is shortening as well. [/QUOTE]
