Where's the barrel pointing at primer impact?

30 caliber bullet from a magnum drops 1.5 inches at 100 yards from horizontal bore axis.

Scope height above bore axis is 1.5 inches.

Stock drop at comb is .5 inch below bore axis.

Stock drop at heel is 1.5 inch below bore axis.

Rifle's zeroed to strike point of aim at 100 yards from the standing (offhand) position.

Where's the barrel pointing relative to the aiming point where the scope's reticule's on at primer impact from the firing pin?

If your bullet drops 1 inch at 100 yards then the barrel is pointed one inch above point of impact. If it drops 50 inches at 500 yards then your barrel is pointed 50 inches above point of impact.

"off hand" Anywhere from 4 to 8 inches from the aiming point for a decent shooter,
a lot worse than that for average shooters. I assume this is a trick question.

I'll interpret this to mean the barrel's pointed 1.5 inches above point of impact (or aiming point).

It's not a trick question. I'm just trying to find out where folks think the barrel's pointed relative to the target when the round starts firing.

Since point blank range on the round should be way out I would have to say the same.
If it has a 1.5 drop to the target and is still on it's way up it has to be pointing very close
to the drop above the target.

Here's something for readers to think about.

Handgun front sights' are higher above their bore axis than their rear sights; this is for square notch rear and post front sights.

Side by side double rifles' bore axes cross at 15 to 30 yards to center both barrels' groups at the point of aim at 50 to 60 yards. The greater calibers and harder kickers' barrel axis cross closer.

The recoil axis in the rifle stated is a few inches above where its stock rests against the shooter.
