[QUOTE="Bruce Treloar, post: 1984113, member: 104002"] It's not rocket science so I'll keep it simple. All chambers vary re lead into the lands, slow powders usually shoot better well off the lands . Fast powders are usually better on or just off, however there are exceptions so start about 10-25 thou off then try by increasing the jump 10 thou at a time. I wouldn't think going more than 60 thou is necessary. You will be able to tell from the horizontal or vertical group which way to go in or out. One rifle I had used to shoot 1/4' 15 though off and after rebarreling it needed to be 55 thou off the lands to produce that sort of accuracy. [/QUOTE]
