Unless a bullet is manufactured non-symmetric, as in twisted fluting in a given direction, it matters not whether it's shot from a left or right twisted barrel.
If twist really matters on target impact & performance, & I really can't say either way, someone post up some test results in gelatin that shows the difference.
Absence of some controlled testing it's just hypothetical & what someone thinks the observed in tissue damage.

I agree with the first sentence in the quote, above. I was just pointing out an extreme example when I posted.
Sentence two, with respect to rate of twist (not direction) I've seen it. I don't have test results as they are all back at my old place of employment - I retired in 2012.
