I was wondering, is the important factor in bullet stability distance or time? If a given projectile is rotating a bullet in a certain twist barrel, does the twist have to be the same irrelevant of speed, or will speeding up the bullet allow you to open up the twist rate?

Comparing 300 blackout to 300 winmag, if shooting the same projectile would the same twist need to be used, or would the greater speed of the 300 winmag allow a slower twist to get the same revolutions per second to stabilise the same, or would you require the same revolutions per metre?

Hope the question is a bit clearer than mud, but let me know if I’ve confused you. Sadly it’s not related to any upcoming purchases, just curiosity
