[QUOTE="Mram10us, post: 1793718, member: 111667"] Everything is math. Call me crazy, but I don’t see it as difficult. Years of experience shouldn’t be needed to make some trigonometry equations and find a simple value. Another easy way is drill a piece of ... well anything with a hole that’s .260ish. Stick it over the bullet like a comparator and find your value that way. We’ve already established for every .002” of bore different, the fb measurement changed .0038”. if you don’t want the extra work, call JGS or whoever cause they’ll most likely have a reamer spec for that bullet [/QUOTE]
