Verifiying Spin Drift

[Depart123]

I know that Bryan Litz has done the calculations for predicting spin drift and incorporated it into his ballistics program. But I would like to know, if anyone has been able to prove the accuracy in real world shooting?

I seem to remember an article or excerpt that mentioned Bryan shooting identical guns and loads, one a right twist and the other a left twist, at distance and factoring out wind to find the actual spin drift. However, I haven't been able to find the reference.

Does anyone know where I can find this article or another reference where this has been tested in actual shooting?

I found the reference. It is detailed in Bryan's book "Modern Advancements in Long Range Shooting Vol.1" chapter 12.
