Too high of a twist rate + too much velocity can cause the bullet to deform or even shatter after leaving the barrel due to centrifugal force. I would postulate if that does happen, it will significantly affect accuracy.

During the D.C. Sniper hubbub, Katie Couric did a sit-down with an ATF agent, on the TODAY Show. She was rolling a .223 round in her fingers, and said “ I understand these bullets are particularly deadly because they spin in flight. “

A 1:9 twist rate will stabilize the SS109/M885 62 grain bullet. A 1:7 rate is needed to stabilize the L110/M856 tracer (it's longer).

An 80 gr. Sierra HPBT Matchking requires a 1:8 twist rate. My groundhog gun is 1:8, barrel from Lilja.

That is a silly question. Of course it does! Or go ahead and try a 1 in 48 twist on a modern rifle and get back to me.

The rate has to be constant for the utmost accuracy.

Not sure this is true. Many benchrest guys use gain twist barrels with success.

Depends on the weight of the bullet. Heavier bullets need a faster twist to stabilize them.
