So, what's the windage based on 7920 FPS

What's the hold off in a 10 MPH cross wind?

I'm thinking hold center might work.

Do you think the tips melt on these?

Even if the tip is aggregate diamond nanorod.

According to some sources, the velocity is only as low as it is because much higher and it simply wouldn't reach the target.

I bet someone here can estimate the lag time.

Better yet, what is the wind velocity at 20,000 feet?

One of these and a groundhog on a rock, good times.

ROTFLMAO at that mental image. Aim low, rock and rat both explode into vapor.

The caption reads that the projectile is emerging from the breach; seems like someone crossed a few wires.

I don't know about this particular one, but in some railguns, the armature is destroyed (by the incredible current) and turned into plasma within the barrel, and would appear as a cloud of flame from the barrel.

My projectiles typically emerge from the muzzle.
Reporter likely doesn't know the difference.
