[QUOTE="Topshot, post: 612394, member: 13285"] 52-33=19 divide by 2 = 9.5" Seems a bit much for Spin drift even with Coriolis thrown in as well. But I just punched the numbers into "Shooter" for a .308 with 155gn bullet and they are similar for a Northern Hemisphere location when SD and CE are taken into account. [/QUOTE]
