Heck, now you've thrown a wrench in the terminal performance equation! Don't bullet mfg. engineer the skives in bullets for Right Hand Twist?
Ok, that was just a joke.
Actually, not a joke, at all. Look at some of the fluted, solid projectiles. When I first saw them I asked "What happens if you shoot it from a Colt?".
The Mfg. looked at me and said "Why would it matter"?
"Left hand twist", I said.
Everything matters. The key is in knowing when it matters enough to be a consideration.
