Re: Grouping satisfactory?
Excellent bullets shot from excellent barrels in excellent condition rarely have any nutating or base and tip spinning around their trajectory axis regardless of how long they are. And those that do typically dampen out in the first 100 yards anyway. And unless the barrel's crown is bad or the bullets are quite unbalanced to begin with, they will fly downrange with their long axis tangent to (parallel to) their trajectory all the way to the target.
Read Sierra Bullet's Rifle Reloading manuals for what's probably the best info on this I've seen.
