Thread: BC and spin rate

I was listening to a Podcast today, Long Range Pursuit EP 127 Meet the new 7PRC.

If I understood them correctly, at one point they were saying the BC of a bullet changes if you spin it faster.

My interpretation was the same bullet has a higher BC if fired from a 1 in 9 twist vs a 1 in 12 twist.

Is this correct? I have never heard of this before, and can anyone link me to further reading or information on this?

Maybe this is common knowledge that I missed but then wouldn't ballistic calculators require the spin of your barrel?
