Thread: Projectile vs barrel length

I have found more twist is better than less.

Litz says more RPM = higher BC, & the velocity penalty is typically less than the usual ES.

Obviously in extreme situations too much twist is less than desirable, ie .224 40 grain @ 4500 fps in 1-8 or .375 350gr SMKs @ 3400 fps with 1-7 exit twist

I thought Litz said that too fast spin and you get large spin drift, but that the effect of spin drift disappears at longer distances i.e.gradually corrects itself over distance.
