I have an understanding of the extreme time and energy that is required to regulate a double. I just had a weird thought the other night and wondered what if. I figured someone on here might know the answer.

What happens when a double using rifling of the same twist rate in both barrels is built, but with opposing directions of twist? Would that have any bearing on the bullets placement in the real world. (I'm sure under perfect circumstances they would fall into the same hole irregardless of the turn of twist, but I've also found that this world is far from perfect, and usually gives vastly different results than perfect "predictions".)

It is a rather stupid question, I guess, but for some reason I am being eaten by the what if factor. Maybe it is from too much coffee and nicotine, but hopefully someone more intelligent than me has an answer and can ease the nagging from a pretty much useless question.
