Russ, I shot 1000+ yards in Quebec across a lake from shore to shore. Wind doping is much easier because at any distance you'll always have ripples to look at. As far as my drop it wasn't any different. I had a first round hit at 983 yards on a 14" wide rock sticking 12" out of the water before I moved further out.
I'm curious if anyone has any theoretical knowledge on shooting over water.
Kevin, I'm not sure there is much theory behind it as gravity still pulls over water
although I could be wrong.
