I have shot locally in the rain. I wear glasses, and what works for me is to use a non fogging solution for the lenses (something I started in my younger Hockey days, and has carried over to my JCG shooting) Also wearing a hat with a brim. I wear my USMC cover. If my dope holds, than the majority of my rapid fire groups are where I want them. Rain or shine though it seems I would always like those groups tighter!

Semper Fi, Rob
