For me, this bead is way too large for the V. I prefer a wide V.
Regardless, the bead is still way too large for that V, or the V is way too small. I do prefer the flattened V, with the bead sitting in the bottom of the valley, as it does on my 14 bore rifle.

The manner in which my rifles with beads are sighted, the bullet or ball impact is ALWAYS in the centre of the bead.

Bear in mind, I do not have any rifles sighted as in the picture. Wrong size V and bead.

Yes - it appears to me, the aiming/point of impact is too high on that stag.

A high lung shot is supposed to bleed them out more quickly, but I do not agree with that premise. I much prefer a shot through both lungs and aorta above the heart, as I do like to eat a heart that is not damaged by the passage of a bullet or ball.
