No, am not boasting at all thanks

Just got a question. I get the heavier bullet being spun like crazy will be flatter at long range (beyond 1km). But is there a cost shooting such a fast twist? Is spin drift noticeably worse than 1/9 for example?

If the bullet is perfectly round, faster is better. But if you have a very slight unbalanced bullet, the faster twist will make it more unstable compared to a slower twist rate if that makes sense?
And if it's too fast, the bullet will come apart mid air and never get to the target...
