3,600 yard shot

That's just crazy. At that distance you have to start factoring in the curvature of the earth. David

Don't really need to worry about the curvature of the earth so much as the rotation of the earth (coriolis effect):

Noobish question 2: if anyone can shoot sub-MOA at 100 yards, could they also be capable (assuming they knew the formulas or had someone tell them where to point at) of making that shot?

I'll disagree with Markm on this. It takes a bit more that someone telling you where to point the dangerous end to make hits at those distances. If it were that easy everyone would be doing it.

I think Mark was saying the rifle might be able to do it. Obviously small mistakes in hold and trigger break which don't factor heavily at 100 or 200 yards begin to vary results more dramatically at 800 yards and beyond.

WOW just WOW! Thanks for sharing that. Amazing

Look at 1:12

The cant on that Picatinny rail is extreme. I bet you can't even zero that rifle short of 500+ yards.

Am I nuts or is it higher in the rear?!? Shouldn't it be the other way around?

Nope.
To get longer/higher trajectory the barrel needs to point upward.

Thanks for the corrections. I knew it was something like that. It is quite amazing and way beyond my basis of knowledge. David

Not just that, you have to factor in how far the earth moves in the 7 seconds of flight time.

Probably have to account for the tides/gravitational pull of the sun and moon if you shoot much further....

I recall there being a extensive thread over on the centering around a custom build that was supposed to sub moa out to 5k. Supposedly there was some .mil interest in it but the site went FUBAR and idk what happened to it.

Saw the video the other day. If he indeed walked that in with three shots, that's impressive.
