Note of caution, at a recent BDS range day it was cracking flags weather and I kept my sunglasses on by mistake when shooting.
Group was 3 clicks right called by

I adjusted my scope then realised I had my sunglasses on, took them off, Group was 3 clicks left so our scope back to where it was!!

We were both in Africa last week and, although I wore a baseball cap or a wide brimmed Tilley hat at times I wore sunglasses but removed them to shoot
