[QUOTE="RockyMtnMT, post: 2386934, member: 7999"] The 285g .338 cal Hammer Hunter calculates at 1.5 sg in a 9" twist at standard atmosphere. We have found that adding altitude to the Miller formula with copper bullets does not work. I think all the calculators are flawed. Then comes dynamic stability for which there is no calculator. The longer for caliber the bullet gets the more trouble there is with dynamic stability. [/QUOTE]
