[QUOTE="User4302021, post: 1635691, member: 105322"] It has been a while since I really dug into the specifics, I'm not all that good with this stuff anyway. I'm smart enough to learn what I need to learn, but lazy enough that I boil it down to what I can take away and forget the rest fairly quickly. It was a conversation with Jim Boatwright about his latest papers that provided the nugget that spin drift, for any given bullet, was a predictable percentage of drop. That percentage, while potentially different for every bullet / rifle combo, fell most commonly between the 1% to 2% range. Jim's paper was exploring the effects of hyper-stabilization of solid projectiles in the 20 turns per caliber range. However, in doing so it used data from extensive gov't 6DOF testing of bullets in the 28 to 32 twist per caliber range. This is the range of twist where most cup and core lead bullets are spun.
