Re: water

My theory is that any winds are more concistent versus winds over broken terrain therfore making shots in wind more predictable. Other than that, no adverse effects that I am aware of.

My answer to this is. The only reason is to make the 7 RM look good. There is no other reason.

Re: water

I've shot over a large lake before at around 800 yards, 600 yards of that was water and we were only a couple hundred vertical feet above the water and shooting at about a 30 degree angle uphill. The shots seem to repeatably be high too. I watched the vapor trail of the bullet look like it almost rose upwards when it went over the body of water. I'm not sure if it was due to the angle we were shooting or the moisture condensing directly above the body of water having an effect on the bullet. This was years ago before ACI's. Good question, I'm curious if anyone has any theoretical knowledge on shooting over water.

Re: water

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.

Kevin, I'm not sure there is much theory behind it as gravity still pulls over water although I could be wrong.

Re: water

I'm curious as to what time of year you guys were shooting over water.

The reason I ask is because in the spring it will take the water longer to warm than the surrounding land so in effect you would be shooting through a cooler mass of air that is directly over the water, exactly the opposite in the fall.

Now weather or not that would have any measurable effect on point of impact is beyond me, but since were talking theory I thought I'd pitch it out there.

Re: water

Colder air is a little more dense then warm air. This would slow the bullet caused by drag. Just a thought.
