[QUOTE="RB II, post: 2755775, member: 124418"] For measuring the chamber, I typically use a spent casing and insert the chosen bullet into the case mouth, insert that into the rifle chamber, close the bolt, extract and measure with dial caliper. I typically do this several times to insure correctness. I only have hunting rifles, so EXACT measurements to determine jump for maximum accuracy isn't my point. Chamber pressure from a bullet jammed into the lands is, I like to load bullets that are more forgiving as far as jump is concerned. Thanks. [/QUOTE]
